Free Online Video Compressor — FAQ
How much can I compress a video?
Compression depends on the source format and codec. Typically, you can reduce file size by 50-80% using H.264/H.265 with minimal quality loss.
What is the best compression format?
For maximum compression, use HEVC (H.265) or AV1. For the best balance of compatibility and compression, use H.264 in MP4 container.
Will compression reduce quality?
With proper settings (CRF 18-23), quality loss is barely noticeable. Higher compression (CRF 24+) will reduce quality more noticeably.
