About AVI Compression
AVI (Audio Video Interleave) is Microsoft's legacy video container. AVI files are often very large because many were created with minimal or no compression — especially those from older camcorders and screen recorders.
CocoConvert's AVI compressor re-encodes the video stream using H.264 within the AVI container, achieving modern compression levels while maintaining AVI compatibility for legacy systems that require it.
For most users, converting AVI to MP4 (available on CocoConvert) is a better long-term solution. But if you need to keep the AVI format for specific software compatibility, our compressor delivers significant size reduction.
Reduction of 60-85% is common, especially for uncompressed or DV-codec AVI files from camcorders.

Frequently Asked Questions
What are the limits for AVI compression?
CocoConvert lets you compress AVI files with no signup required. You get 5 files per hour (up to 250 MB each) on the starter tier. Pro users get 100 files per hour and 5 GB per file.
