When creating an NFT on OIX, you can upload files up to 50MB.
If your file is larger than 50MB, you have the option to link to content in the unlockable content field.
You can upload files of these formats:
|Type of NFT||Format|
|Image*||JPG, PNG, GIF|
*Images can be any dimension, but the preview will be 1080x1080, with the aspect ratio of the original.
