How VideoSlim works

2. Choose a one-tap preset, or set your own size or quality.
3. Tap Compress and VideoSlim writes a new, smaller MP4 on your device.

VideoSlim is built for anyone who deals with large video files: creators saving mobile data, families sharing memories, professionals sending footage from the field, or anyone reclaiming phone storage without giving up privacy.

Reduce video size, save phone storage, and keep your videos yours.
