Step 2. Compress AVI Files with 5 Methods

Method 1. Convert to an Advanced Encoder

AVI is often encoded through Divx/XviD/MPEG4/H264. Compared with these old codecs, H265/HEVC and VP9 are more advanced and can encode a video to a much smaller size with high-quality preserved. So you can convert AVI to H.265 (HEVC for MP4) to make the AVI file smaller.

Click the format image on the right side of the interface to expand the output format list. Go to the "Video" category and choose one format from either "H265 for MP4" (recommend), "H265 for MKV", or "VP9".

If you don't want to change the video format, you can select the output format as "AVI" and go on to other compression methods.

Method 2. Adjust AVI Video Parameters

Video parameters like resolution, bitrate, and frame rate can affect the video file size. So you can adjust these parameters to shrink the AVI file size. But note that this way can inevitably cause some quality loss.

Open the "Parameter settings" and you can see the related parameters. Just choose a preferred one from each drop-down list. You can also head to the "Quick setting" section to drag the sliders to your preferred resolution.
