How much can I compress a video?

Depending on the original encoding and your quality settings, you can typically reduce video file sizes by 30-70%. Videos with high bitrates or inefficient codecs will see the most dramatic reductions.

Will compressing my video reduce quality?

Some quality loss is inherent in compression, but at our 'Balanced' setting the difference is barely perceptible to the human eye. For critical content, use the 'High Quality' setting for minimal visible impact.

Is my video uploaded to a server?

No. All compression happens directly in your browser using WebAssembly. Your video file never leaves your device, making this safe for confidential or sensitive content.

Can I compress videos for Discord's 25MB limit?

Yes. Adjust the compression slider toward 'Maximum Compression' to reduce your video below Discord's file size limit. You may also need to trim the video length for very long clips.

What video formats can I compress?

Our compressor works with MP4, MOV, AVI, MKV, and WebM files. The output uses H.264 encoding for maximum compatibility.

Frequently Asked Questions

About Video Compression

Video compression works by reducing the bitrate of your video file using efficient encoding. Our compressor uses H.264 (x264) encoding with adjustable CRF (Constant Rate Factor) values to give you fine control over the quality-to-size tradeoff.

Lower CRF values (18-22) produce larger files with excellent quality, while higher values (28-35) create much smaller files with more visible compression artifacts. The default "Balanced" setting at CRF 23 is the sweet spot for most use cases.
