Pro Tips for Best Video Compression

Optimizing video is about balancing file size with visual fidelity. Our Free Video Compressor handles the heavy lifting, but these strategies will help you get the best results.

1. Choose the Right Quality Setting

The CRF (Constant Rate Factor) slider controls quality. CRF 23 is visually lossless for most content. CRF 28 offers excellent quality at significantly smaller sizes. For screen recordings and presentations, CRF 30+ works great since they have less motion.

2. Downscale When Possible

If your video will be viewed on mobile devices or embedded in websites, 720p is usually more than sufficient. Dropping from 4K to 720p can reduce file size by 75% or more with negligible quality difference on smaller screens.

3. Trim Before Compressing

If you only need a portion of a long video, trim it first using our Video Cropper tool. Shorter videos compress faster and produce smaller files.
