Media Bitrate Checker: Guide
- Intent
- Media bitrate checker online: inspect codec, bitrate, sample rate, channels, resolution, and streams locally in your browser (no uploads).
- What it does
- Uses FFmpeg logs to parse stream information (audio/video) and display a readable summary.
- Key features
- Stream list (audio/video), Overall bitrate, Large-file warning
- Privacy
- Your media stays on your device. This page downloads the FFmpeg WebAssembly engine; files are never uploaded.
- Best for
- Preflight checks before you send files to clients, editors, or ad platforms
- Diagnosing why a file is huge (codec/bitrate/fps/sample rate issues)
- Anyone searching 'bitrate checker online' who prefers local inspection (no upload)
- Why this tool
- Quick technical summary without running ffprobe in the terminal
- Local-first FFmpeg processing: files stay on your device
- Practical output: stream list + bitrate hints you can act on
How to use
- 1Drop a media file into the tool (audio or video).
- 2If prompted for large files, confirm you want to continue.
- 3Review overall bitrate, duration, and each stream's details.
- 4Use the info to choose export settings or diagnose large files.
Common mistakes
- Assuming the 'overall bitrate' is always present (some containers do not report it clearly).
- Trying to analyze huge files on low-memory devices (can crash the tab).
- FFmpeg engine download requires a modern browser; some environments may fail to load it.
Examples
Check MP3 properties
Drop: song.mp3
Read: codec, bitrate (kbps), sample rate (Hz), channels (stereo/mono)
Video stream check
Drop: clip.mp4
Read: resolution, fps, video bitrate, audio codec.
