Apple's own folder icon, in the colour you actually wanted.
and nothing gets uploaded.
The whole editor. One folder, one field, one row of colours.
Same tool, two folders. Pick a colour and the fill and depth controls appear — they stay out of the way until there is something to apply them to.
It starts from the real thing
The base is Apple's current Folder_512x512@2x.png, pulled off a Mac. Every colour and every word is layered over that — not a redrawn folder that looks almost right.
Nothing leaves the browser
The editor and the PNG export both run client-side. Artwork you drop in is never uploaded, because there is nowhere for it to be uploaded to.
The web is the short path
A colour and a word covers most days. Two-colour fills, etched and embroidered surfaces, app-icon extraction, and applying straight to a Finder folder live in the CLI.
From the terminal
The same renderer, plus the parts the web version does not have. It ships as @sz.ws/foldio, and the studio CLI routes anything it does not recognise to that scope — so the line below is the whole setup. Nothing is installed.
$ npx sz.ws foldio make WORK --tone ember --fill tint
- Writes work.png — an ember folder with WORK embossed across it.
$ npx sz.ws foldio make --app /Applications/Things.app --folder ~/Projects
- Takes the icon Finder actually shows for an app and applies it to a folder. Files inside are untouched — only the folder's icon metadata changes.
$ npx sz.ws foldio system-icon -o macos-folder.png
- Extracts this Mac's current system folder icon, for reference or as a starting point.
$ npx sz.ws foldio presets
- Prints everything you can pass: six colours, four fills (native, tint, duo, splash), four surfaces (none, emboss, etch, stitch).
