How Our AVI Compressor Works
Our tool uses industry-standard H.264/H.265 codecs with optimized settings to compress AVI files efficiently. You can adjust the Constant Rate Factor (CRF) from 18 to 28 - lower values preserve more quality while higher values create smaller files. We also support resolution adjustment, allowing you to downscale from 4K to 1080p, 720p, or lower as needed.

About AVI Format
AVI (Audio Video Interleave) is a multimedia container format developed by Microsoft. While older than MP4, it's still widely used and offers good quality. Compressing AVI files can significantly reduce their size as they often contain less optimized codecs.
