Reduce a video to under 100 MB
100 MB is a common limit for upload forms and file-sharing tools, and a sensible size for high-quality longer clips. It's generous: ten minutes of 1080p still gets over 1 Mbps, and short 4K phone clips can be cut from hundreds of MB to 100 MB with little visible loss.

Compress to 100 MB →How to do it
- Open the compressor with a 100 MB target.
- Load your video.
- Trim if you only need part of it.
- Keep the original resolution for short clips; choose 1080p for 4K sources.
- Compress and download the MP4.
Tips
- Approximate video bitrate at 100 MB: 2 min ≈ 6.5 Mbps, 5 min ≈ 2.5 Mbps, 10 min ≈ 1.2 Mbps.
- Large inputs take longer and need more memory; desktop browsers handle them best.
- Downscaling 4K to 1080p is usually the single biggest size win with the least visible cost.
