How it works

What happens to your file.

The file signature is matched against known formats, the structure is parsed where the format allows, and everything found is returned as JSON. The file is not modified.

Questions

Common questions.

What if the extension is wrong?

The detected type comes from the file contents, not the name, so a mismatch is reported. The MIME Type Detector focuses specifically on that comparison.

Does this show EXIF from photos?

Basic image details appear here. For the full EXIF block including GPS, use the Image Metadata Viewer.

Is my file stored?

It is temporarily staged to produce the report. The processing workspace is removed after processing.
