Free browser-side tools

Inspect folders in your browser before changing anything on disk.

These tools run locally in your browser on folders you select. Nothing is uploaded or modified. When you want to delete duplicates, batch-rename files, or clean up clutter on your drive, use the desktop app.

Photo privacy utility

Check your photos for GPS, camera, and timestamp metadata before you share or archive them.

Scan local photos for common EXIF privacy leaks and download stripped copies client-side when the browser can safely re-export them.

EXIF warningsGPS flagsClient-side strip

What this tool does

  • Reads EXIF locally without uploading images.
  • Flags GPS coordinates and device fields you may want stripped before sharing.
  • Pairs with Dupe Zappa duplicate review and photo cleanup workflows.

Privacy check

Surface location, device, and timestamp leakage before you share.

The scan stays local. When the browser can safely re-export the image, you can download a metadata-stripped copy without touching the original.

Local metadata scan

Pick a photo folder and inspect the privacy footprint.

Your browser is using the directory-selection fallback. The scan remains local, but empty folders cannot be detected.
