FAQs
Frequently Asked Questions
Quick answers about how this tool works and when to use it.
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.
