## FAQ

### How do I compress a video without losing quality?

Choose the High quality preset. The compressor re-encodes the video with an efficient H.264 codec at a higher bitrate, which lowers the file size while keeping the picture close to the original. For the smallest possible file, use the Small preset, which trades some visual quality for size.

### What is the maximum file size I can compress?

There is no hard limit because the work happens on your own device rather than on a server. Very large files (several gigabytes) depend on your computer's available memory, but typical social and marketing videos compress without issue.

### Does it add a watermark?

No. The compressed video has no watermark, no logo, and no quality lock. It is the full output, free to use.

### Is my file uploaded to a server?

No. This tool runs entirely in your browser using your device's own hardware. Your video never leaves your computer, nothing is uploaded, and nothing is stored. That also means it works on private files without any privacy risk.
