Inspect video or audio file (codec info)

See what is inside a video or audio file — codecs, dimensions, duration, audio tracks, color and metadata. Read on your device, never uploaded.

Inspect a video or audio file to see exactly what’s inside it, without uploading anything. Read the video codec, resolution, frame rate, duration, bitrate, audio tracks, color space and metadata tags — all on your device. Useful for diagnosing why a file won’t play on a certain device, checking the codec before converting, verifying audio track layout, or seeing what metadata a file carries. Everything runs in your browser, so the file stays private. Free, no account.

How it works

  1. Open a video or audio file from your device
  2. Read the codec, dimensions, duration and metadata
  3. Nothing is uploaded — the file stays on your device
