NFT Files: What Size and Format Should You Use?

We all know what a jpg file is. We have been downloading our favorite athletes’ or film stars’ pictures in this digital format file from the internet since the ’90s, most of the time for free.

How will you feel if you know a jpg file has been sold for 69.3 million dollars? Yes, it’s true. But this surge in the price of a jpg file has been possible because it was sold as an NFT file.

Being an NFT file adds an unexpected extra value to the digital files, attracting creators to create new NFTs. But there are some rules and restrictions regarding which format and size a creator can upload his NFT files in a marketplace. If you don’t know the conditions, your files can be rejected.

So, here we are with the complete guide on the size and formats of NFT files that will make your life easy as a creator of the NFT.

What does NFT File mean?

NFT file is no critical concept to understand. Any digital format file of images, audios, videos, 3D models, collectibles, and so on will be considered as the NFT files if the creator uploads them on the blockchain through marketplaces as NFTs, which means non-fungible tokens.

A non-fungible token or NFT is a unique, non-interchangeable artwork available on the blockchain and can own by only one person at a time. An NFT file, in simple words, is any digital format artwork that is minted as NFT on the blockchain.

The supported file format for an NFT file is jpg, jpeg, gif, mp4, JPG, PNG, GIF, FVG, MP4, WEBM, MP3, WAV, OGG, CLB, GLTF, and the format is determined based on whether it’s audio, video or image file.

NFT doesn’t have any limitation on the size of any file. But each marketplace has its own rules about file size. The maximum size of an NFT can vary from 10 MB to 3 GB according to the marketplaces they are minted.

Because they find it difficult to operate their platforms if there are different sizes of NFT files in different formats, marketplaces emphasize following a standard guideline about maintaining size and formats when creating and minting NFTs.

Problems of Minting a Large File

Minting a too large non-fungible token file will lead to some unwanted occurrences. The typical outcome is that the marketplace can reject your file at the time of minting. The file cannot be taken by the system and not uploaded. There is another option to take place. Maybe your file doesn’t get rejected, but you will find a corrupted copy of your file after uploading.

Again, the marketplace can allow you to upload large files. But you can lose patience and cancel the uploading of your NFTs as it takes a considerable time to upload for a large file. Fear of losing sellers due to slow upload is one reason marketplaces have been bound to the limit of the size of NFT files.

If you attempt to upload a larger size file than the supported size of the marketplace, it will result in problems during processing files.

Moreover, you can be harmed financially because of the gas fee when you decide to burn your non-fungible tokens. Financial loss can occur at the time of NFT minting, too, even if the minting fails as gas fees are high for larger files.

However, file size affects gas prices when files are minted and if the artwork’s metadata is stored on the blockchain. The gas fee doesn’t get higher for larger files at the transaction time.

NFT File Size Upload Limitations and Supported Formats

Uploading an NFT file of any size or format is impossible as each marketplace specifies its supported size and types. As requirements are different due to marketplaces, you should carefully read the rules and regulations on supported NFT size and types they provide on their official websites. It will save you from future problems while minting NFT on a marketplace.

We have collected information about the requirements regarding the size and formats of NFT files from different official NFT marketplace, which should be followed when minting NFTs. If you read this section of this article, you will know the accepted file size and types of all crucial NFT marketplaces.

OpenSea

Founded in 2017 by Alex Atallah and Devin Finzer, OpenSea is the oldest, largest, and most popular NFT marketplace nowadays. For the wide varieties of NFTs, it provides, OpeanSea is cherished among the creators, sellers, and buyers to find their desired NFTs.

OpenSea offers the opportunity to its users to upload files with a vast size like 100MB files. However, this platform advises keeping the file size under 50 MB to maintain the quality of the NFT and the website’s efficiency. OpenSea allows JPG, GIF, PNG, MP4, SVT, MP3, WebM, WAV, GLTF, GLB, and OGG as file types in their platform.

OpeanSea gives its users to mint relatively large size files compared to other marketplaces. It is another reason why OpeanSea is at the top of the list of the NFT marketplaces. It would help if you went through their instructions about file size and formats before minting NFTs on their platform.

Rarible

Rarible is one of the most famous NFT marketplaces founded in 2020 that are hugely used by both collectors and creators, similar to OpenSea. But as to the NFT file size, it allows creators or sellers to upload in their platform, Rarible is in no way comparable to OpenSea.

While OpenSea allows sellers to upload files of 100 MB, Raible allows only 10% of it. You guessed right. The maximum file size Rarible allows 10MB. In Raible, the accepted file types are WebP, PNG, MP4, GIF, MP3, JPEG, etc.

Rarible is a decentralized autonomous organization that allows its users to earn governance tokens called $RARI, which they can use to vote for the changes in this marketplace. This platform lets its users create several NFTs for a single image and sell them several times.

SuperRare

SuperRare is an Ethereum blockchain-based platform that claims to be an art gallery. Like Rarible, this platform has a token called $RARE for its users, allowing users to have a future vote on the platform. 

SuperRare asks its users to upload NFT files in PNG, JPEG, GIF, MP4, GLB format, and they determined 50MB as the maximum file size limit for the artworks uploaded on their websites.

Some suggestions are available on their website regarding uploading different files in SuperRare. They suggest its users use a thumbnail file while tokenizing an MP4 or GLB file that should not be up to 10MB in size, and the format should be in PNG, JPEG, or GIF. The thumbnail can be cropped and compressed to fit the SuperRare website, affecting its colors.

When uploading MP4 files, this platform advises using the H.264 or X.264 codec and not to use H.265, HVAC, MPEG-4, or WEBM.

SuperRare requests its users to double-check the NFT before tokenizing whether their uploaded NFT displays correctly in the browsers or not. Otherwise, burning and re-minting the token can be needed in the future because of faulty upload.

Foundation 

Foundation is an auction format marketplace that offers various NFTs to collectors. Founded in 2020, this platform runs each auction for 24 hours, following the reserve price was met or not.

Foundation allows you to upload NFT files from their website’s “Create an NFT” page. An NFT file can be 50MB maximum in size in Foundation. The file types are supported as images in this platform are JPG, GIF, SVG, and PNG. The supported video file format is MP4, and a 3D file is supported in GLFT or GLB format.

The ideal width is 3000px or less for still images, and 1080p or 4K resolution is considered best for video files. Foundation told that the NFT files would be compressed to exhibit on the website, and landscape or square size artworks seem perfect at the platform’s layout.

Mintable

Mintable is the best option to upload a huge NFT file.

Primarily, Mintable is known for its gasless minting. As gas fees can be one of the most expensive aspects of buying NFTs, offering gasless minting helped the mintable gain popularity in the NFT users community. Though, there are some limitations on what you can mint via gasless minting of NFTs.

The platform also allows normal minting and “printable minting,” allowing artists to mint an NFT collection on the marketplace and remove unsold artworks later.

What we told you before, as a Mintable user, you are free to upload NFT files in extended sizes. They allow its users to upload NFT files up to 3GB in size, including an overview file if they are privately downloadable. Any file types are accepted for privately downloadable file upload.

But while uploading preview images, the file size limit is 200MB, and any image file along with mp4 or GLB format video is supported for preview images. They suggest that the preview images file size should be more than 800px x 800px in dimension.

Mintable recommends uploading a GLB file or an MP4 file as one of the preview images to ensure anyone can reach your uploaded 3D image. You will still need to upload a basic image file as preview images, though.

KnownOrigin 

KnownOrigin offers the opportunity to the artists to create genuine and innovative digital collectibles and allows everyone to buy, sell, and collect different kinds of unique NFTs.

The supported size for the NFT files is 75MB maximum in the marketplace and 25MB maximum for the cover images of the NFTs. You can upload your NFT files in formats of PNGs, JPG, GIFS, SVG, WebP, WebM, Mp4, and GLB on this platform.

This Ethereum blockchain-based platform has been very exclusive about choosing the artists they want to work with on the marketplace since its launch in 2018. An artist can have to wait for months to reply with acceptance or rejection after filling up the application to work with them. An artist needs to pay a 15% commission on the first sale while using KnownOrigin but has the chance to gain 10% royalties on all secondary sales as well. 

Mintbase

Mintbase is a PoS blockchain-based NFT marketplace, while most of the marketplaces are Ethereum Blockchain-based. But the NFT files uploaded in the platform can be moved to the other marketplaces run on Ethereum blockchain by specific technology.

Mintbase allows its users to upload NFT files in JPGs, GIFS, and PNGs format for images up to 10MB large, and its supported video file formats are MP4, MP3, and OGG, which can be up to 16MB.

Mintbase is one marketplace that allows creators to mint very small-size files.

BinanceNFT

Founded in 2017 by Changpeng Zhao, this marketplace is considered a crypto powerhouse. Binance NFT Marketplace lets its users create NFTs like many other marketplaces and lets the users mint the non-fungible token quickly.

The NFT file-formats BinanceNFT accepts, according to their official website, are JPEG, PNG, and GIF for image, MP4, MPEG, and AVI for video, and WAV and MP3 for audio.

The maximum size of all NFT files should not be more than 50MB.

Only pre-approved creators can mint NFT following the accepted NFT file size and formats. However, BinanceNFT said they would widen the opportunity for every registered user to mint NFT files henceforward.

Bakeryswap

Bakeryswap is another significant NFT marketplace that introduced the MuskDoge NFT option to make its users’ experience of minting NFT easier and quicker.

This marketplace recommends mint images with not more than 10MB, with a 3:4 ratio. They ask to upload NFT files in .jpg .png or .gif format.

Minting the NFT file is possible from the “image upload window” of the Bakeryswap website by ticking the’+’ sign.

After uploading the file, you have to click on the mint option and wait for approval. Then your NFT will be listed on the blockchain. Remember, Bakeryswap is very strict about copying artworks. If your NFT file is not original, they will take it away from their marketplace.

Decentraland

Decentraland launched in February 2020 and is prominent as an open-source 3D virtual world platform. Supervised by a nonprofit Decentraland Foundation, this platform allows its users to buy virtual plots of land in the form of NFTs with the MANA cryptocurrency.

Decentraland allows its users to upload 15 MB files per parcel in size, including 3D models and audio tracks. But the size of the file, like node.js packages that won’t be uploaded on the platform, isn’t counted in the total size of the uploaded files.

The allowed number of the NFT files in Decentraland is 200 files per parcel. These are the complete numbers of the files that can be uploaded to the marketplace’s server, including 3D models and audio tracks. Not uploaded files like node.js packages are not included in the file amount.

Decentraland only accepts 3D models in glTF format, which stands for GL Transmission Format. This gITF is an open project by Khronos used for 3D scenes and models. A glTF file is a perfect web-compatible tool for 3D modeling and uses only .gltf or .glb as the file extension.

The Size of Some Famous NFT Files

You can have a rough idea of which size is ideal for an NFT file by going through the sizes of some famous NFTs. For instance, the eminent NFT based game Axie Infinity characters are measured as 512px by 384px. Released in March 2018, this game in .apk format is available on different platforms is around 48MB to 64MB for downloading.

CryptoPunks

One of the oldest NFT projects is CryptoPunks of Larva Labs, released in June 2017. The project consists of 10,000 unique characters, and only one person on the blockchain owns each character. Each character of the collection of Cryptopunks is 336px by 336px in size.

Everyday

Everyday: The First 5000 Days is a large NFT file comparable to common NFTs. Every file size of this collection is measured as 21,069px by 21,069px. This famous digital artwork collection was sold for 69 million dollars in March 2021.

Bored Ape Yacht Club

Created in April 2021, the Bored Ape Yacht Club gained huge popularity. The file sizes of these ERC-721s are 631px by 631px, but their drops on Mutant Apes and Kennel Club are 1262px square which is double the size of ERC-721s format.

Cool Cats

Cool Cats is an NFT collection of large size artworks. This collection of 9,999 blue cats launched in July 2021, and every piece of cats measures 1080px by 1080px.

Meebits is another successful NFT project. Larva Labs launched this project of 3D models in May 2021 after the claps they received by making CryptoPunks. The portraits of these 3D models measure 1024px by 1536px and can be transferred into plenty of games.

Where to Upload Your Large NFT Files?

The best idea for creators is to follow size restrictions regarding creating and minting NFTs on the marketplaces. It will make their experience hassle-free. But there can be plenty of reasons you cannot sacrifice the size of your NFT file, including the chance of reduction of its quality.

In such circumstances, you can go for other options that allow you to upload images, video, or other types of media files in addition to the NFTs while minting NFTs in substitute places by which large size NFT files storing and sharing can be possible.

Google Drive is an outstanding substitute place where you can store your additional high-quality, large-size NFTs and control over who can access them. This platform allows a maximum of 15GB of free storage, which is a fairly big amount. However, this storage includes your Gmail account and google photos.

Pinata is another great alternative file storage place for large NFT files. Pinata stands for an InterPlanetary File System that is similar file storage system to Google Drive. Using this system, you will be able to upload large files and control people’s access to the files.

You have to provide the external file storage service link to your token holer when they buy your NFTs. It will allow the buyers to get access and download all the additional media files you are offering with your primary digital artwork.

Unlike Google Drive, Pinata has no restriction over the storage, and it manages files openly. You can mint your NFT and upload your big files in Pinata. Pinata provides you with 1GB storage space free, which you can increase by giving some monthly fee.

While using Pinata, you upload, store, and manage files on IPFS. IPFS, which means The InterPlanetary File System is a protocol and peer-to-peer network. This decentralized storage system uses distributed, multiple network-based file systems and functions content-addressing to differentiate each file in a global namespace that makes storage management easy.

How to Decrease the Size of NFT Files

You must check the file size requirements of the marketplace where you want to mint your NFT files as a creator. As marketplaces have restrictions over minting too large NFT files, you should choose to go for the standard size that will be accepted almost in every marketplace.

For creating files with the proper size, you can compress your image, video, or audio file for free by using tools available on the internet. While minting NFTs on the marketplace, upload the compressed, decreased, and lower quality files and store the high-quality large size images on a file-sharing system.

Google Drive and Pinata are two well-known file-sharing systems where you can upload the actual size files and share the link with the buyers of your NFTs. Compress files only to mint because it can affect the quality of your artwork.

Wrapping Up

The non-fungible token is the future of fintech. Creative people are trying to take its benefits by entering NFT marketplaces, and you may be one of them.

As marketplaces decide the specific size and formats of NFT files to be minted on their platform, you have to be watchful about the NFT files’ size and formats for the successful minting of your digital assets. If you can’t follow their instructions, the marketplaces won’t allow you to use their platform.
