Video Bitrate Adjuster

What is Video Bitrate Adjuster?

Video Bitrate Adjuster lets you re-encode a video at a different bitrate to balance file size and visual quality. Lower the bitrate to shrink large recordings for sharing, or raise it to preserve detail for archival. Processing runs entirely in your browser using ffmpeg.wasm — your files never leave your device.

How to use

1. Upload your video file (MP4, WebM, MOV, or AVI up to 2 GB).
2. Choose a target bitrate in kbps or Mbps, or pick a preset (low, medium, high, original).
3. Click Re-encode, preview the result, then download the adjusted video.

Result

You recorded a 45-minute lecture at 8 Mbps (2.7 GB). Set the target to 2 Mbps — the file shrinks to ~675 MB while keeping the slides perfectly readable.
