Every share is a statement.
Most of it is involuntary.
Three quiet leaks hiding in an ordinary photo — and the moment you take control.
The photo you posted pins your home to within a few meters.
Serial numbers tie every shot back to the camera in your hand.
MetaWrite closes the case: rewrite the record, or erase it with proof.
One workbench.
Total metadata authority.
Images, videos, PDFs, and Office documents carry hundreds of invisible tags. MetaWrite gives you full read–write–wipe control over all of them.
Inspect
Deep Forensic Tag Inspection
Dissect the full internal metadata architecture — EXIF, IPTC, XMP, GPS, and manufacturer maker notes — in an interactive, searchable raw-tag viewer.
Rewrite
Granular Tag Editing
Don't just delete — change. Rewrite capture dates, GPS coordinates, camera serials, and creator tools field-by-field. Save tag-sets as reusable templates.
Scale
Batch Processing Powerhouse
Sanitize thousands of files simultaneously in the background, with automatic filename-collision safeguards protecting every original.
Prove
Chain-of-Custody Cryptography
Compute MD5, SHA-1, SHA-256, and SHA-512 signatures and export courtroom-ready PDF certificates documenting origins, timestamps, and hashes.
Integrate
Native macOS Extensions
Strip metadata on-the-fly inside other apps with the native Share Extension and Photos Editor Extension. No exporting, no round-trips.
Contain
Map Air-Gap Mode
Geotags plot on native Apple MapKit. Enable Absolute Zero Telemetry and the app cuts all network access — the live map is replaced with a local air-gapped view, so coordinates and your IP never reach external mapping servers.
The workbench, up close.
Straight from the Mac App Store listing: the tools that act on everything the inspector finds.
Other tools delete metadata.
MetaWrite rewrites it.
A stripped file raises questions. A controlled file answers them. MetaWrite is a true metadata editor — every tag is a field you own.
- Rewrite any tag, field-by-field. Capture dates, GPS coordinates, device signatures, creator tools — double-click and type.
- Synchronize file timestamps. Align filesystem dates with EXIF capture times — or set them to exactly what your workflow requires.
- Save tag-sets as templates. Build your standard redaction or attribution profile once, apply it to every case file after.
- Originals stay untouched. Edits export as verified copies with collision-safe filenames and full hash logs.
The Evidence Lab
See what your files are saying behind your back. Open a case sample — or drop one of your own photos. Analysis runs entirely in your browser: nothing is uploaded, ever. Just like the app.

MetaWrite runs entirely on your Mac. No accounts. No third-party tracking. No crash reporting. No external APIs. It works identically in a newsroom, a lab, or a SCIF.
Evidence that survives cross-examination.
Every operation can be sealed with a forensic PDF certificate: source file, export timestamps, and the complete set of cryptographic hash signatures — MD5, SHA-1, SHA-256, SHA-512.
- Courtroom-ready formatting — clean, printable, and unambiguous.
- Before/after documentation of exactly which tags changed and when.
- Batch logs covering entire directories in a single audit trail.
MetaWrite vs. the alternatives
Honest answer: it depends on your desk. Here is how the three roads compare.
| Capability | MetaWrite | ExifTool (CLI) | Online strippers |
|---|---|---|---|
| Interface | Native macOS app | Command line | Browser upload form |
| Files stay on your machine | Always — 100% local, zero telemetry | Yes — runs locally | No — files are uploaded to someone else's server |
| Rewrite individual tags | Field-by-field visual editor | Flags and syntax | Mostly strip-only |
| Hash records & certificates | MD5 → SHA-512 + courtroom-ready PDF certificate | Hashes via separate tooling | None |
| Batch, originals untouched | Collision-safe copies (_1, _2…) | Scriptable — you write the safeguards | Limited, with file-size caps |
| Built for | Investigators, journalists, legal teams | Engineers and pipelines | Casual one-off use |
ExifTool is superb open-source software — plenty of forensic pipelines run on it, and we salute it. MetaWrite is for the desks that need a native interface, sealed documentation, and a guarantee that nothing ever leaves the machine.
