Inspect video and audio metadata in three steps
Use this free media info viewer when you need reliable file details before editing, converting, archiving, or publishing a clip. It is designed for quick checks without installing desktop software.
- 1
Select a file
Choose a local video or audio file, or drag it into the inspection area.
- 2
Let the browser analyze it
MediaKit reads the container and tracks locally with MediaBunny and a Web Worker, so the page stays responsive.
- 3
Review or export
Review codecs, dimensions, bitrate, duration, tags, subtitles, and cover art, then export a JSON report.
Video + audio
Supported formats
Inspect common video containers, camera exports, streaming-friendly files, and popular audio formats. Support depends on the browser codecs available for the selected file.
Video containers
Read container and track information from common camera, editing, and streaming files.
Audio containers
Inspect music, voice, and extracted audio files, including tags and cover art when present.
What you can inspect
The report is organized around the parts of a media file that matter when you edit, convert, publish, or archive it.
Container details
Track & codec data
Tags & artwork
Private by design
Files are selected from your device and processed in your browser. The MediaBunny parser runs inside a Web Worker; MediaKit does not need to upload the file to read its metadata. When you export JSON, the report is saved directly to your device.
Common use cases
A quick metadata check can save time before the next step in your workflow.
- Check resolution and frame rate before editing
- Find the right codec for conversion or playback
- Verify audio channels, sample rate, and bitrate
- Audit tags, subtitles, and embedded cover art
Frequently asked questions
Are my files uploaded?
No. Metadata extraction happens locally in your browser. Your media stays on your device unless you choose to share it yourself.
Which formats can I inspect?
The viewer accepts MP4, M4V, MOV, WebM, MKV, TS, MTS, M2TS, MP3, WAV, FLAC, AAC, M4A, OGG, and Opus files. Very unusual or damaged files may not expose every field.
What information is shown?
Depending on the file, you can see the container, MIME type, duration, file size, video and audio tracks, codecs, dimensions, frame rate, bitrate, language, tags, subtitles, and cover art.
Can I inspect a large video?
Yes, files up to 2 GB are accepted. Large files can take longer to parse and need enough free memory in the browser, but the analysis runs off the main thread to keep the interface responsive.
Why is a field missing?
Some containers or codecs do not store every field. Damaged files, variable frame rates, and browser codec differences can also affect what is available, so an em dash means the source did not expose that value.
