Non-Fungible Tokens (NFTs) are unique digital items stored on the blockchain where ownership can be tracked and verified. NFTs may come in the form of JPGs, GIFS, audio files, or any other digital file type.

You are purchasing a token on the Cardano blockchain uniquely associated with a digital artwork, which proves the authenticity and provenance of the artwork.

A great many of the artists working with us make and sell their physical artworks. The Pixel Gallery does only sell NFTs, however we suggest checking the artist's portfolios for links to their external websites to look for listings of their physical artworks, or use the artist's contact information to send them a message.

Absolutely, go to our artists page or search by Artist Name for your desired artist.

With The Pixel Gallery, artists earn approximately NaN% on the sale of their artworks.

As an online gallery representing emerging artists, we support the intellectual property rights of artists. When an artist creates an artwork, whether it is physical or digital, the artist retains the copyright to their work even after the work is sold. This is the rule under copyright law and standard practice in the traditional art world. Unless a different agreement is made between artist and buyer at the time of sale, the owner of a piece of art has the right to sell and publicly display their artwork, but the artist, not the collector, holds the rights to reproduce for commercial purposes and make other commercial uses of the work. The collector may print out copies of their NFT for personal use.


The Pixel Gallery will not be asking our artists to relinquish their intellectual property rights to token holders. Just like in the world of physical art, the artists will retain full copyrights in their works. This is fully laid out in our Consumer Terms.


To protect the value and scarcity of listed artworks, the artists involved have agreed that they will not mint any other NFTs associated with the artworks each artist placed on The Pixel Gallery.

Cardano, as one of the more modern blockchains is significantly more energy efficient than many of the alternatives. This comes down to the fact that Cardano uses a method called proof of stake to validate transactions. By contrast, proof of work, which is used by most other cryptocurrencies including Bitcoin and Ethereum is more than 1,000 times less energy efficient.


We want this project to live on Cardano because it is the most popular blockchain for NFTs and is likely to have the most staying power and relevance in the long-term. That said, we also recognize the current environmental impact of the Cardano blockchain with regards to energy usage. To partially mitigate the impact of this project, The Pixel Gallery will seek to calculate CO2 emissions from our NFT minting and explore ways that it can reduce the carbon footprint associated with the project. Any offsets bought by The Pixel Gallery will not impact our artists’ earnings on the sale of their NFTs. We will continue to be a part of the evolving conversation around the environmental impact of NFTs, as we complete this project and work towards milestones on our roadmap.

  • The maximum allowed file size is 10 MB.
  • The ideal range of file sizes for most art styles is from 1 MB to 10 MB.
  • We have decided not to impose a minimum file size (see the question below for more details as to why)

A full list of the accepted file types is provided below:
  • jpeg
  • png
  • svg+xml
  • cis-cod
  • ief
  • pipeg
  • bmp
  • x-cmu-raster
  • x-cmx
  • x-icon
  • x-portable-anymap
  • x-portable-bitmap
  • x-portable-graymap
  • x-portable-pixmap
  • x-rgb
If you want to upload an image of a filetype that is not included in this list, let us know.

  • At first, in order to get some sales, we suggest pricing artworks in the low hundreds, which could mean anything from £100-£300. Once some artworks are selling, you should start raising prices as you feel is appropriate.
  • A second method to consider is to pick a percentage of the sale price of your original artworks (for example 80% or 50%), and apply that to the price of your artwork, for example a £1,000 artwork would become £800 or £500 in it's NFT form.

All artists using The Pixel Gallery are required to indicate that they agree to our document called the "Artist's Declaration" before being allowed to submit any artworks.


The Artist's Declaration is shown below:


Giclee prints and postcards would be allowed under the terms of our website, as would sales of all physical forms of the artwork. What we prohibit is for someone to sell an NFT of the same artwork on another website at the same time as, or after selling it on The Pixel Gallery.

Artworks are initially added to our platform as “listings” only, and we mint the NFTs as they are purchased. This means if the artwork hasn’t sold, there won’t be any NFTs of it in circulation. On that basis we’d be ok with you listing that artwork on another platform (provided the artwork is also unlisted from our site). Re-listing an artwork for sale as an NFT only becomes problematic when NFTs of it has already been sold.

We have decided not to impose a minimum file size for the following reasons:
  • Some artistic genres, such as procedural or generative art may naturally have low file sizes since the images are produced by computer code. This can be considered as part of the elegance or style of the artwork.
  • Low image file sizes can always be “upsampled” to create a larger image file size without improving the image quality. This means any file size limit would be meaningless in practice, since the file size of an image can be manipulated to be any arbitrarily large number and it would encourage misleadingly high file sized images to be added to the website
  • File size does not correspond to image quality: Jpeg compression algorithms are so good that often very high quality images can be compressed to low file sizes without a perceptible difference to the human eye. Adding a file size limit might mean that a jpeg with a high quality compression algorithm would not be allowed, while a much lower quality image that is a lossless image format (such as .bmp) would be allowed.
Of course, we still encourage arists to upload the highest possible quality images of the artwork available to them. We have been known to take images down from the website that we do not believe to be of suitable quality to sell. The file size and image quality should be appropriate to the type of artwork being listed, in particular photographs of physical artworks should be high quality.
