stampla

Your photo archive, verifiable for decades.

Stampla stamps every photo and video with its own identity: when it was captured, and what it contains — a name derived purely from the file itself. Nothing to maintain, nothing to lose: the archive can prove its own integrity at any time.

What the name buys

Everything on one timeline

Sorting by name is sorting by capture time — across every camera, phone and scanner. IMG_0001 (2).jpg never happens again.

Verifiable

The name is reproducible from the file, so the whole archive can be re-checked at any time: corruption is told apart from legitimate edits, and duplicates identify themselves.

Groups stay whole

A RAW file, its sidecars and its edits form one group — everything shares the master’s name and is renamed together, atomically.

The desktop app

From memory card to verified archive

The desktop app covers the whole workflow: import cards, check the archive's health, fix names, undo anything. Every action is a preview first — nothing changes until you say so.

The Import view after copying a card: a green banner reads "Card fully accounted for — safe to format", above the list of copied files with their new names.
Import ends in a verdict, not a guess — every copy is re-hashed at its destination before the card is cleared for formatting.
The Verify view: findings grouped by meaning with plain-language explanations — a date disagreement shown with the old time in red and the corrected time in green.
Verify explains findings in plain language, worst first — and tells corruption apart from ordinary edits.
The Relocate view: two files planned to move, each shown as its current folder and the folder its name says it belongs in.
Names carry their own filing: Relocate puts files back where their name says they belong — and hands Lightroom-managed folders to Lightroom.
  • Safe by default — previews everywhere, one Apply, journaled changes with one-click Undo, and Resume for interrupted runs.
  • Built for real archives — live progress with a Stop button, tested against hundreds of thousands of files.
  • Nothing hidden — every action can show the exact terminal command it stands for.
  • Grows with the archive — file event shoots into their own folders, or change the naming scheme with a guided, verifiable migration.

First launch: macOS asks you to approve the app in System Settings → Privacy & Security — the build is not notarized yet.

Free and open source — also on PyPI for any platform, source on GitHub.

Lightroom Classic

Plays well with your catalog

The publish plugin mirrors your catalog into plain folders.

Shooting through Lightroom Classic? The publish plugin keeps a plain folder tree in step with your catalog — and the archive tools respect what Lightroom manages, handing renames to it instead of breaking its links.

Safety model

Nothing changes until you say so

Every tool is a dry run unless explicitly applied. Applies are validated as a whole before anything is touched, journaled before the first change, applied atomically per file group, resumable after an interruption and revertable afterwards — undo re-verifies content before deleting anything. A file whose capture time cannot be resolved is reported, never renamed. Nothing is ever overwritten.

For advanced users

The same engine, from the terminal

 stampla import /Volumes/CARD --apply
  DSC_0001.NEF    Photos/2026/2026-07/20260703_150727_9b677b64.nef
  DSC_0001.xmp    Photos/2026/2026-07/20260703_150727_9b677b64.xmp

card fully accounted for: 1 group imported and verified — safe to format

The engine is a dependency-free Python package — stampla on PyPI (Python 3.11+, ExifTool on PATH). --json and --json-stream make every command scriptable; the command guide has the details.
