The Suite

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 Killer Feature

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.

HASH-VERIFIED DOCUMENT

Chain of Custody

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.

Questions from the field

When exactly does MetaWrite launch?

July 2026. The app is complete and in final review with the Mac App Store. Want a ping the moment it's live? Contact us and we'll notify you personally.

Does MetaWrite ever send my files anywhere?

No. MetaWrite runs 100% locally with zero telemetry — no accounts, no analytics, no crash reporting, no external APIs. For strict air-gapped environments, enable Absolute Zero Telemetry: the app cuts all network access entirely, deactivating even the Apple MapKit view in favor of a local air-gapped placeholder — so file coordinates and your IP address never reach external mapping servers.

Can it change metadata, or only delete it?

Both — and editing is the point. MetaWrite Pro lets you rewrite individual tags (capture dates, GPS coordinates, device identifiers, creator tools), synchronize filesystem timestamps with EXIF data, and save tag-sets as templates for repeatable workflows. Wiping everything is just one button among many.

What file types are supported?

Images (JPEG, PNG, TIFF, HEIC, and RAW formats), videos, PDFs, and Office documents. The inspector shows EXIF, IPTC, XMP, GPS, and manufacturer maker-note blocks.

Are edits destructive to my originals?

No. Edited and sanitized files export as copies with automatic collision-safe filenames (_1, _2…). Your originals — and their hash records — remain intact for your case file.

Will certificates hold up as documentation?

Certificates are formatted for professional use: source file details, export timestamps, and MD5 / SHA-1 / SHA-256 / SHA-512 signatures in a clean, printable PDF. Many teams attach them directly to case files and evidence logs. (As with any tool, admissibility rules vary by jurisdiction — consult your counsel.)

Mac only?

Yes — MetaWrite is a native macOS app, built for both Apple Silicon and Intel, distributed exclusively through the Mac App Store. Native means fast: batch jobs run in the background using Apple's frameworks.
