What is video metadata?

Video metadata is the descriptive information stored alongside a media file. It can include the file name, format, size, duration, dimensions, and aspect ratio, which are all useful when you need to understand a clip without opening it in an editor.

Metadata tools are especially helpful for checking whether a file matches upload limits, screen aspect ratios, or platform requirements before you publish or transcode it.

Tool description

This tool reads basic metadata directly from an uploaded video file in the browser. It displays the file's technical details, shows a preview player, and lets you download the extracted information as JSON.

It is useful for quick inspection when you want to know what is inside a local video file without uploading it anywhere.

Features

  • Fast metadata lookup: Reads duration, dimensions, and size from the uploaded file
  • Preview player: Lets you confirm the video visually before you use it elsewhere
  • JSON export: Provides a downloadable metadata report for sharing or automation

How it works

The tool loads the file into the browser and waits for the video element to report its metadata. Once the browser exposes the loaded values, the tool formats them into a readable summary and a JSON export.

Limitations

  • It only reads information the browser can expose from the local file.
  • Corrupted or unsupported video files may not load correctly.
  • The tool does not transcode or repair media.
