Video Compressor

File size reduction depends on the preset you choose. Light compression reduces size by about 30% with nearly lossless quality, medium compression achieves around 50% reduction with minimal visible difference, and heavy compression can shrink files by up to 70% with some noticeable quality loss.

Two-pass encoding analyzes the entire video first to understand which scenes are complex and which are simple, then distributes the bitrate more intelligently during the second pass. Use it when you want the best possible quality-to-size ratio and can afford the extra processing time.

No, the audio track is preserved during compression. The compressor re-encodes the video stream to reduce file size while keeping the audio intact. You can also choose to downscale the resolution for additional size savings.

CRF stands for Constant Rate Factor and controls the quality-to-size tradeoff. Lower CRF values produce better quality but larger files. A CRF of 18 is considered visually lossless, 23 is the default balanced setting, and values above 28 produce smaller files with noticeable quality reduction.

Video compression is processed on our server using FFmpeg, a professional-grade encoding tool. Your video is uploaded securely, compressed with your chosen settings, and automatically deleted within one hour after processing completes.
