What this photo reveals

Where it was taken, the camera's serial number, the owner's name — and how to remove them.

PDF

Check a document before you send it

Black boxes that hide nothing, deleted text still inside, comments and who wrote them — in PDFs and Word files.

EML

Check an email before you trust it

See where replies go, whether sender checks passed, and which server sent it.

Film scans

Inspect a set frame by frame, then process local JPEG or TIFF copies in your browser.

See the synthetic frame-detection test

A simple illustration tests the detector; it is not a photograph.

For the curious: look inside a file

Look inside

Why a file won't open, and how it is built: every byte explained, with where its format defines it.

  • Bytes view — the structure beside the hex, every part with its spec reference
  • Find / — text or hex, and the part of the file it falls in
  • Compare — two files, or a file and its clean copy
  • JSON — the whole structure, with its explanations
  • Command line and CI — the same checks in a CLI and a GitHub Action
