The tool re-encodes the video at a lower bitrate using H.264 or H.265 codec, which reduces file size while maintaining acceptable visual quality.
Typical compression reduces file size by 50 to 80 percent depending on the original bitrate and the quality setting you choose.
No. Compression only reduces the bitrate. The resolution (width and height) stays the same unless you choose to resize.
The compressor uses H.264 (AVC) by default, which offers the best balance of quality and compatibility. H.265 (HEVC) is available for even smaller files.
Yes. The tool supports 4K video compression. Compressing 4K to 1080p significantly reduces file size while maintaining good quality for most uses.
Resolution is the pixel dimensions (e.g. 1920x1080). Bitrate is the amount of data per second. Reducing either reduces file size. Reducing bitrate affects quality; reducing resolution affects detail.
