How it works
Input cleanup: Strips query strings and fragments from URLs, then reads the file name.
Extension detection: Uses the last dot or common compound endings like tar.gz.
MIME match: Looks up the extension in a curated, common MIME list.
Private: Everything runs locally in your browser with no uploads.
Common use cases
- Checking Content-Type headers for uploads
- Validating file extension policies
