Generate local FFmpeg commands
Copy an MP4 or WebM command with codec, bitrate, width, audio and fast-start settings ready for a local terminal workflow.
Avoid browser upload limits
The tool does not upload or transcode video files. It creates a compression plan that keeps large client files on your device.
Compare savings quickly
Use current size, duration and bitrate metrics to decide whether a compression target is realistic before publishing.
Frequently asked questions
No. It estimates output size and generates an FFmpeg command so large videos can be compressed locally without uploading files.
The estimate uses duration and target video bitrate. Actual output can vary because codecs, motion, audio and encoder settings affect final size.
It generates package-free command snippets for MP4 with H.264/AAC and WebM with VP9/Opus.
No. The tool only uses the numbers you type and returns a command; your video files stay on your device.
