Free Online Video Metadata Viewer
Inspect and extract detailed technical specifications, dimensions, durations, and formats of your video files securely. Runs entirely client-side — your video is never uploaded to any server.
How it works
- Drop a video file or browse — file is read via local object URL.
- Browser decodes header to extract resolution, aspect, duration, and audio presence.
- View specs in structured tables with mono-tabular values.
- Copy info as text (with polite aria-live) or export as JSON.
What you get
- General file info: name, size, MIME, last modified
- Video stream details: resolution, width/height, aspect ratio, orientation
- Playback specs: duration, duration seconds, audio presence, playability
- Copy and export actions with accessible feedback
