Media Info Viewer

Drop in an audio or video file to read everything about it: container, codec, bitrate, duration, resolution, frame rate and every track inside, without opening a heavy media app.

A media info viewer reads the technical details of an audio or video file without opening a heavy editor. Drop in an MP4, MKV, MOV, MP3 or WAV and see the container, codec, bitrate, duration, resolution and frame rate for every track inside, so it works to check a video's codec or read audio file details. Knowing the exact codec explains why a clip plays on one device but not another. The file is inspected on your own device with nothing uploaded.

Frequently asked questions

Which audio and video formats are supported?
Most common containers and codecs, including MP4, MKV, MOV, AVI, WebM, MP3, WAV, FLAC and AAC. The tool reports whatever tracks the file contains.
Why does my video play on one device but not another?
Usually because of the codec. This viewer shows the exact video and audio codec, so you can confirm whether a device or player supports it before re-encoding.
Can it read very large video files?
Yes. It only reads the parts of the file that describe its structure, so even multi-gigabyte videos are inspected almost instantly without loading the whole thing.
