About Compress Video

Compress video files to reduce their size while maintaining visual quality, entirely in your browser. Control the compression level using the CRF (Constant Rate Factor) slider –lower values mean higher quality and larger files, higher values mean more compression. Choose an encoding speed preset from ultrafast to veryslow. The tool uses H.264 encoding via FFmpeg, producing widely compatible MP4 files. Perfect for sharing videos by email, uploading to platforms with size limits, or saving storage space. Processing happens 100% locally –your videos never leave your device.

Frequently Asked Questions

What CRF value should I use?

CRF 23 is the default and good for most uses. CRF 18-20 is visually lossless. CRF 28-35 provides strong compression for web sharing.

What does the preset control?

Preset controls encoding speed vs compression efficiency. "fast" processes quickly but produces larger files. "slow" takes longer but achieves better compression.

Is there a file size limit?

The tool handles files up to 500 MB. Larger files may be slow depending on your device.
