About Video Compressor
Video Compressor using your browser's built-in canvas and recording APIs — no ffmpeg, no upload, no queue. Pick a maximum width and a bitrate (or leave it on Auto); the video is re-recorded through a canvas at the smaller size. The clip plays through once in real time while being re-recorded as a WebM (the video format browsers can create natively), so a 2-minute video takes about 2 minutes. Your footage never leaves your device.

Frequently asked questions
How do I video compressor?+
Drop the video, set the options, and press Process. Pick a maximum width and a bitrate (or leave it on Auto); the video is re-recorded through a canvas at the smaller size. Then download the WebM output — entirely in your browser.
Why is the output WebM and not MP4?+
WebM is the only video format browsers can encode natively without shipping a 30 MB ffmpeg download. It plays in every modern browser, WhatsApp, Telegram, YouTube and most editors; convert to MP4 with a desktop tool if a legacy device demands it.
Why does processing take as long as the clip?+
The browser re-records the video in real time as it plays through a canvas — that's what makes a fully private, no-upload tool possible. Trim the range first to process just the part you need.
Is my video uploaded?+
No. Everything happens locally; your footage is never sent to a server.
