Rolling experimental improvements, opinionated features & workflows.
- Beautiful UI — Dark theme, clear hierarchy, reskins planned.
- Open as folder & convert many files — Use In Folder Convert and the File System Access API: pick a folder, choose formats, convert. Files are written directly into that folder — no download step. Optional: move originals into
_originals/after conversion. - Drag & drop — Drop files or folders onto the page. Ctrl+V (or Cmd+V) to paste from clipboard.
- Quick shortcuts — Press
1with a single file loaded to convert to the first suggested format instantly. Type to filter formats, Esc to clear. Suggested formats are sorted by category and your recently used choices. - Single-file workflow — Drag out the converted file from the browser into any folder (no download clutter). Or use Share (Web Share API) or Download. Optional auto-download for single-file conversions.
- Batch options — Convert multiple files without folder write access? Download N files or Download as ZIP (one archive).
- PWA — Install as an app from the browser for a native-like launcher (no offline support in this fork).
Yes. (The scroll/filter perf probably gives it away.)
One goal was to push the limits of prompting: you still need solid knowledge of web APIs, browser gotchas, and power-user shortcuts to get a decent frontend. Without that, this UI wouldn’t exist.
Mostly. A few ideas didn’t pan out (yet):
Copy to clipboard Nice in theory, but many file MIME types can’t be written to the async Clipboard API without errors, so clipboard paste isn’t reliable for arbitrary converted files. We use drag-out instead.
Chrome extension Still under consideration. A quick UI triggered from the extension could be handy, but you can already “install” the site as an app. Replacing file inputs on random sites with a custom converter UI doesn’t seem like a reliable workflow yet — need to understand real use cases better.
Electron app Under strong consideration. Using real FFmpeg in a desktop gives much better performance and also native explorer integration would be a big thing. Might happen in a few days if i dont forget of this repo.
Mobile native app Out of scope for now; could be revisited later.
