What is rExif?

rExif is the metadata editor for photos and videos on your Mac. Wrong dates, missing locations, cryptic file names: fix them on one photo or thousands at once, and every change shows up in orange as a preview before it’s written to your files. Nothing on disk changes until you click Save, and your photos never leave your Mac.

Key Features

  • The right dates, even in bulk: shift every date by an interval, for example when the camera clock was an hour behind, or correct it from one photo whose exact time you know
  • Dates from wherever they are: from the file name (IMG_20230514_123456, WhatsApp, screenshots, Pixel…), the folder name, or Google Takeout JSON files; dates in sequence, missing ones filled in from their neighbors, time zone changes
  • File dates aligned: file creation and modification dates matched to the capture date in one click
  • Location on the map: drag photos onto the map to set their location, or search for a place by name
  • Automatic location: from the photo closest in time, from a GPX track (Strava, Garmin…), or from Google Takeout; city, state, and country from the coordinates
  • Copies to share: export copies without location or personal data
  • Text and keywords: camera, lens, description, author, and copyright; templates with placeholders such as ”© {year} Jane Smith”, plus find and replace across every item; keywords and star ratings, also read by Lightroom
  • Batch rename: with a template, for example {date}_{nnn}
  • Work fast: a table with customizable columns, search, and quick selection (no date, no location, suspicious dates, by camera…); copy metadata from one photo and paste it onto others; export and import as CSV to fix it in a spreadsheet
  • Review before you save: every change can be undone, redone, or reverted; Quick Look with the space bar
  • Every format: JPEG, HEIC, PNG, and TIFF rewritten without recompressing the image; MOV, MP4, and M4V without re-encoding; RAW (CR2, NEF, ARW…) and AVI, MKV, MTS stay untouched, with metadata in an .xmp next to them, read by Lightroom, Bridge, and Premiere
  • Photos library: change the date and location right in Photos, or export the originals
  • Built for macOS: drag into the window or onto the Dock icon, “Open With…” in Finder, reopens your previous session
  • Light, dark, or automatic appearance: interface in English and Italian
  • No subscription: free, with no ads and no in-app purchases

Platforms

Available on macOS 15 Sequoia or later, for Macs with Apple silicon and Intel.

Privacy Policy

Updated: October 7, 2026

Data Collected
The app processes information you enter directly: the photos and videos you choose to add, the Photos library items you pick in the system picker, their metadata (dates, GPS location, camera, description, author, copyright, place, keywords, and rating), the files you use while editing (GPX tracks, Google Takeout JSON, CSV, .xmp), the files created at your request, the session, and the app's preferences (language, appearance, thumbnails, table columns). We do not collect sensitive data (health, payments, location, contacts, biometrics). No account or registration required.
Advertising & Tracking
No in-app advertising. No tracking or analytics — data is never sent to external servers for profiling.
Data Storage
All information stays on your device. Photos and videos are read and edited entirely on your Mac and are never uploaded to any server. The only network connections go to Apple services for the map, place search, and city names, and only when you use those features.
Third-Party Sharing
We do not sell or share data with third parties.
Your Rights
You can access, modify, and delete your data directly within the app.
