Contact

Feedback and file-type requests help us expand the database and improve detection.

Contact

If you have feedback, found a file type we should support, or want to report a bug, this is the place.

What to include

For the fastest help, tell us:

What you expected the tool to detect
What it showed instead (detected type + confidence)
The file extension (if any) and where the file came from
Device + browser (example: Android Chrome)

Privacy note

Please do not send personal or sensitive files. The main tool is designed to run locally in your browser without uploading. If you choose to contact us outside the tool, share only non-sensitive details (like the extension and the app that created the file).
