Processing happens locally in your browser. Your files and inputs are not uploaded to our servers.

What Video Metadata Viewer does
The HTML media element exposes dependable playback metadata such as duration and intrinsic dimensions. File size and MIME type come from the selected File object; codec and frame-rate details are shown only when the browser exposes them.
Examples
- Check a video’s duration before sharing it.
- Confirm whether a clip is portrait, landscape, or square.
- Inspect the MIME type reported by the local file picker.
Frequently asked questions
Is my input uploaded?
No. This tool processes its input locally in your browser. Normal page requests do not include the contents you enter or select.
Why are codec or frame rate missing?
Standard browser media APIs do not consistently expose codec and frame-rate metadata for local files. Missing values are labeled unavailable.
Will it work in every browser?
The tool uses modern browser APIs. Current Chromium, Firefox, and Safari releases provide the best support; the page displays a clear error when a required capability is unavailable.
