Video Bitrate Adjuster

What is Video Bitrate Adjuster?

Re-encode any video at a different bitrate to trade file size for visual quality. Lower the bitrate to shrink large recordings for sharing, or raise it to keep detail for archival. Powered by 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.
