Shrink a video with CRF compression

Same resolution, smaller bytes: raise CRF for more compression (and more artifacts). Output is MP4. To change height to 720p/480p use Resize video; to cut length use Trim video; to just get H.264 compatibility use Video to MP4. Files stay on your device — Freela does not upload them.
