Creativity deserves
an open door.
Puffles Studio is a free, no-code NFT collection generator that runs in your browser, with a free cloud build for heavy collections of up to 10,000. A collection starts with an idea. We believe the tools to bring it to life should be within everyone’s reach.
Less between you
and your next big idea.
Puffles Studio turns folders of artwork into unique NFT collections. It brings the collection-building workflow to the web, with the same careful control over layers, rarity, and rules.
The studio runs in your browser, and a free cloud build is there for heavy collections of up to 10,000. The studio asks for a quick sign-in with your email or a wallet, with no password and no fee; your artwork stays on your device unless you choose a cloud build. You bring your traits, make your choices, and download what you create.
Free to make.
No subscription, no export fee, no watermark. Every creator gets the same tools.
Yours to keep.
Your artwork stays on your device unless you choose a cloud build, which is deleted after a few days. You choose where the finished collection goes.
Room to play.
Explore combinations, change your mind, and start again. That’s part of making something good.
Made for the details.
Exact trait counts, compatibility rules, one-of-a-kind pieces, and metadata you can take with you.
What it makes.
And what it leaves to you.
The details are in How it works, the Learn guides and the Privacy policy.
Up to 20,000 NFTs.
From one folder of PNG, JPG or WebP images per trait type: up to 64 layers, 2,000 traits per layer and 10,000 images per import. Rarity by weight or exact count, never-together rules, and up to 2,000 1 of 1s.
Files ready to publish.
PNG or JPEG images at any width from 64 to 8,192 pixels, one OpenSea-style metadata file per NFT, _metadata.json, rarity.csv and OpenSea’s drop spreadsheet. One ZIP, laid out the same whether it was built on your device or in the cloud.
Every picture, checked.
Puffles counts how many different pictures your traits can make, not just lists of traits. It knows when a trait hides others, whether it fills the whole picture or covers part of another, like a mask over the eyes. After building, it compares every image and warns you if two came out the same.
No minting, no hosting.
It doesn’t mint, deploy contracts or host your files, and it writes metadata for Ethereum-style (EVM) chains only. Upload your images wherever you like, set their address in the studio, and mint with the service you choose.
