How to Reduce AVI File Size with Best AVI Compressor

Here we take WinX HD Video Converter Deluxe as the chosen AVI size reducer tool. Download it first to our Windows computer, install and open it. Then you can reduce AVI file size as following four ways:

1. Reduce AVI File Size By Adjusting Its Parameters (Recommended)

AVI is just a video container, and the file size of AVI video purely depends on the codec it uses and other parameter settings like bit rate and resolution. Using video editing software or video converter program to reset those factors by following the rules:

#1 Lower Resolution: The higher video resolution (width x height) is, the larger AVI video will be ( of course with other parameters unchanged). Thus you just change the resolution to a lower one, like from 1920x1080/1280x720 to 640x480.

#2 Lower Bit rate: The higher bit rate a video owns, the larger video size and better video quality you will get. But do notice don't make it too low, otherwise the image quality can be really bad.

#3 Change Codec/Format: The video codec of AVI often lies in Divx/XviD, and the audio codec lies in AAC/AC3/MP3. You can convert/re-encode the data to make AVI file smaller. Generally speaking, converting AVI to MP4 (MPEG4/H.264) is the top choice for compressing AVI file size. If you'd like to upload large AVI to YouTube, sending to someone via email, FLV format is considerable. When you choose "MP4 Video" at General Video for example, you can place the scroll bar to "LQ/Fast".
