Understanding file information
Choosing safe settings
The inspector reports metadata such as file type, dimensions, duration, size and a SHA-256 fingerprint. A fingerprint is a repeatable identifier that helps compare two copies; it is not a password and does not reveal file contents.
Matching SHA-256 values strongly indicate identical bytes. Different values mean the files differ even when names and appearance match. Do not trust a filename extension alone as proof of format.
Troubleshoot methodically
Use the reported properties to diagnose unsupported uploads or select a source before conversion. Scan unfamiliar files with trusted security software before opening them.
A file may be valid but unsupported by one player. Test it with a current media player and inspect its video and audio codecs. Missing sound can indicate an unsupported audio stream; a black screen can indicate unsupported video hardware decoding. Converting to MP4 with H.264 video and AAC audio is the most widely compatible fallback.
Privacy and safe handling
Share only the fields needed. Never include passwords, private messages, precise location or unrelated personal files. Exact reproduction steps are often more useful than excessive telemetry.
A practical selection checklist
If a local file is rejected, confirm that the extension matches its actual type and try a smaller known-good sample. Refresh the page, then test another modern browser. If a public address fails, verify that the complete address opens without a private login, copied surrounding text or an expired temporary token.
