Details

The online compressor can export WebM or MP4 depending on the selected engine. Native apps support additional app-focused outputs for offline workflows.

Start compression, wait for the browser to process the video, compare the file size reduction, then download the optimized result directly to your device.

VideoSlimmer helps you shrink videos for sharing, storage, email, chat, cloud backup, and publishing while keeping the first workflow local to your browser.
