How to use this tool
- Upload any video file.
- The browser's media element reports duration, dimensions, and MIME type.
- The tool also scans the first 512 KB for printable text tags in the file header (useful for MP4 © tags, encoder strings, GPS, etc.).
Limitations
Browser APIs expose duration, width, and height but not codec details or deep container metadata. For full codec/container analysis (bitrate, video/audio streams, codec names), use MediaInfo (desktop app) or ffprobe.
Why it's private
The video is loaded into browser memory only — it is never sent to a server. Only the first 512 KB is read for tag scanning.
