Wondering if a clip is 1080p, how long it is, or whether the sound is stereo? This page checks an audio or video file and shows a short summary.

How to inspect a file

  1. Upload an audio or video file up to 80 MB.
  2. Press Convert file.
  3. Read length, size, format, and stream details on the result page.

What you get

A readable list, not a wall of JSON. Typical rows:

  • Length
  • Size
  • Format (MP4, MOV, WebM, and so on)
  • Video (resolution, codec, frame rate)
  • Audio (codec, channels, sample rate)

Internal temp paths and encoder junk stay hidden.

When this is useful

  • Before you send a file to someone who asked for “1080p AAC”
  • When a player refuses a file and you want to know why
  • When you are not sure if a download is audio-only or has a picture
