How do I inspect deep technical metadata and container structure of a media file?

Drop any image, audio, or video file into the Media File Inspector to parse binary headers, MIME type, file signature magic bytes, resolution, codecs, and stream properties.

Can I verify if a file extension matches its true MIME format?

Yes. The inspector checks binary magic bytes (e.g. `ÿØÿ` for JPEG, `PNG` for PNG, `ftyp` for MP4) to detect spoofed file extensions.

Can I inspect EXIF, IPTC, and XMP metadata tags?

Yes. Parses camera make, lens model, exposure settings, ISO, date, and GPS coordinates.

Can I copy technical inspection reports?

Yes. Copy structured JSON reports for forensics or QA documentation.

Are files uploaded during inspection?

No. Binary ArrayBuffers are parsed locally in browser memory.

What formats can be inspected?

Supports JPG, PNG, WebP, GIF, MP4, WebM, MP3, WAV, PDF, and ZIP files.
