Collection Generator

Bring your own traits. Build your own collection.

Upload a ZIP of your own image layers, choose the stacking order, set the rarity of every trait, and generate unique NFT artwork with matching metadata and a CSV — ready to download in one ZIP. Works for any NFT project. Everything runs in your browser: your files are never uploaded, and nothing is minted.

Files stay on your device — nothing is uploaded to a server. PNG, JPG/JPEG and WebP. Up to 512.0 MB.

• Each top-level folder is one layer. Its name becomes the layer name.
• Each image inside is one trait. Its file name becomes the trait name.
• Use any layer names and any number of layers. No folders inside layer folders.
• Use the same image size for every trait, with transparent backgrounds on upper layers.
