Resize for the destination, not for a technical number
Choose familiar aspect-ratio presets instead of manually calculating dimensions. FitMyVideo can fill the frame for an immersive social-video crop or fit the full source inside the target frame.

Browser-native processing first
On supported browsers, resizing uses WebCodecs through a media pipeline designed for the web. That reduces the need to run a full software FFmpeg stack for every job.
Keep your original private
The file stays in the browser-processing workflow. There is no upload queue and no cloud copy required by FitMyVideo.
