Fast, private, browser-based image curation — your photos never leave your device.
🌐 snapsortr.com · Works offline · No account required · Chrome / Edge
SnapSortr is a high-performance web tool for rapidly reviewing and sorting large collections of local images. Select a folder from your disk, browse through images at speed, and mark each one as Take, Drop, or Undecided — then export only the photos you want, with your original folder structure preserved.
Built for photographers, content teams, and anyone who has ever stared at thousands of raw shots and wished there was a faster way to cull them.
Your images never leave your device. Ever.
- SnapSortr uses the File System Access API to read files directly from your local disk.
- No images, filenames, or metadata are uploaded to any server.
- No analytics on your files. No cloud sync. No account.
- All session progress is saved locally in your browser's IndexedDB.
- Works fully offline after the initial page load.
- Select a folder — recursively scans all supported image formats instantly.
- Review images — single-image view or virtualized grid, whichever is faster for you.
- Mark decisions — Take ✓, Drop ✗, or leave Undecided. Changes auto-save as you go.
- Export — download a ZIP or copy files directly to a folder, preserving the original directory structure.
- Keyboard-first — sort through images without touching the mouse.
- Virtualized grid — thousands of thumbnails rendered without lag.
- Instant navigation — blob URLs are created on demand and revoked immediately after use; no memory bloat.
- Streaming scan — images appear progressively as the folder is scanned.
- Progress auto-saves to IndexedDB on every decision.
- Session history — resume any past session with one click, across browser restarts.
- Export progress JSON — download a full record of your decisions to back up or share.
- Import progress JSON — restore a previous session's decisions on any machine.
