About Screenshot Organizer
Screenshot folders get out of hand fast — hundreds of nearly-identical captures from product reviews, bug reports, design exploration, app testing. Screenshot Organizer turns that pile into a sortable, reviewable, exportable set without leaving your browser. Drop in any number of files, sort by date, name, file size or pixel dimensions, optionally group everything by capture day into folders, and export the whole tidy result as a ZIP. Exact duplicates (byte-identical files saved twice) are flagged automatically so you can spot redundant copies at a glance, and an optional batch-rename pass replaces unhelpful default names like Screenshot 2024-04-12 at 14.32.18.png with sequential pattern of your choice.

How it works
- 1
Drop your screenshots
Add up to 1000 images at once. The tool reads each file's dimensions and computes a SHA-256 to flag exact duplicates.
- 2
Sort & group
Sort by name, date, size or pixel area. Toggle 'Group by date' to bucket files into per-day subfolders in the export.
- 3
Rename & download
Optional batch rename pattern (e.g. screenshot-001.png). Export as a ZIP — files on your disk are never modified.

Frequently asked questions
Are my files uploaded to a server?
No. Every tool on SnapToolz runs entirely inside your browser using JavaScript and WebAssembly. Your file is read locally, processed in memory, and the result is offered as a download. Nothing is sent to a server — there isn't one to send to.
How are duplicates detected?
We compute the SHA-256 hash of each file's bytes — two files with identical bytes get the same hash and are flagged as duplicates. Different file sizes or different compression always produce different hashes, even if the images look identical to a human. For visually-similar (but not byte-identical) detection, use the Duplicate Image Finder.
Will the original files on my disk be renamed?
No. Files are read into the browser, repackaged into a ZIP under their new names if you enabled rename-on-export, and the ZIP downloads. Your originals on disk are untouched.
What's the limit?
1000 files per batch. Beyond that, browsers start running out of memory on lower-end phones. Process your screenshots in chunks if you have more.
Does it work offline?
Yes. SnapToolz is a Progressive Web App. After your first visit, the app is cached on your device and every tool keeps working without an internet connection.
Is SnapToolz free?
Yes — every tool is 100% free with no sign-up, no watermark, no hidden tier. The whole platform is open source and we have no plan to gate features.
