Why use this inspector?
Nothing Uploaded
Your file is read entirely in your browser. Unlike most online media-info tools, it's never sent to a server.
Video & Audio
Works for both: codec, resolution, frame rate and HDR for video; codec, bitrate, sample rate and channels for audio.
Powered by MediaInfo
Built on MediaInfo.js - the same engine behind the well-known desktop tool, running locally via WebAssembly.
Any Format
MP4, MKV, AVI, MOV, WebM, FLV, TS, plus MP3, FLAC, WAV, AAC and more - read metadata even from formats the browser can't play.

Media Inspector FAQ
Is my file uploaded?
No. The file is read entirely in your browser using MediaInfo.js (WebAssembly). It never leaves your device.
What information can it show?
Container/format, duration and overall bitrate; for video: codec, resolution, aspect ratio, frame rate, bit depth, color space and HDR; for audio: codec, bitrate, channels, sample rate and bit depth.
Does it work for audio files too?
Yes - MP3, FLAC, WAV, AAC and more. You'll see codec, bitrate, sample rate and channels.
Can it read formats my browser can't play?
Yes. Metadata is read from the container, so you can inspect MKV, AVI or HEVC files even if the browser can't play them. To actually play them, open the file in OnlinePlayer.
