What the Video Compressor does
Make a video smaller for email, messaging apps or upload limits. Compress by quality level, or enter a target file size and let the compressor calculate the bitrate for you. Lowering the resolution at the same time gives the biggest savings.
Options
- Compress by quality level (18 = best quality, 40 = smallest) or by target size in MB.
- Limit resolution to 1080p, 720p or 480p.
