Video Compressor FAQ

Common questions about how to compress video with our tool.

Is this video compressor safe and private?

Yes, 100%. We use WebAssembly technology to run FFmpeg inside your browser. Your video data never leaves your computer, making it completely secure.

How small can I compress video files?

Use the "Target File Size" option to compress video to an exact limit like 10MB or 25MB. Extremely aggressive compression may affect quality, so preview before downloading.

How much can compression reduce file size?

It depends on the original video. Often, you can reduce file size by 50-80% with minimal perceived quality loss, especially for high-bitrate recordings.

Can I compress 4K video?

Yes, but processing 4K videos requires significant memory (RAM). If your browser runs out of memory, try using Chrome/Edge on a desktop, or scale down to 1080p.

What video formats are supported?

Our video compressor supports MP4, MOV, AVI, MKV, and most common formats. The output will always be a widely compatible MP4 file.

Why is my compressed video still too large?

Try lowering the resolution (e.g., from 1080p to 720p), reducing the target quality percentage, or using CRF mode with a higher value (28-35). For very short videos, file overhead may limit how small they can get.

Is this video compressor really free?

Yes! It's 100% free with no limits. You can compress video as many times as you want, with no watermarks, no file size restrictions, and no signup required.

How long does it take to compress video?

Processing time depends on file size, resolution, and your device. A typical 100MB video takes 1-3 minutes on a modern computer. Progress is shown in real-time.
