Part 1: Why Do We Need to Compress AVI Files?

AVI stands for Audio Video Interleave, which is a common video file format for data that contains both audio and video. The AVI files are usually of high quality but normally with large size. The huge size of the AVI files may cause many inconveniences, such as taking up a lot of space of hard drive and being difficult to upload and share online.

So if your AVI files are too large, you can compress them to save storage space. Moreover, compressed AVI files are also more efficient for sharing with friends or uploading to YouTube and some other websites. In this circumstance, I will show you how to downsize AVI file to a smaller size while preserving high quality with the best video size compressor. Now, download it here to get started!

Method 1. Change the Advanced Encoder to Shrink AVI Files (High-quality Preserved)

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) or change the codec to the VP9 encoder to make AVI file smaller.

Free downloadFree download this program before starting the process.

Step 1: Launch HD Video Converter Factory Pro and open the Converter module. Then, hit the +Add Files button to load the AVI files. Or you can also drag and drop the source AVI files into the program.

Step 2: Click the big 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.

Step 3: Click the bottom triangle button to set the destination folder and press the Run button to start the AVI compression.

Compress AVI Without Losing Quality

If you want to output the compressed video in the original format, then go to see the following methods.

Method 2. Downscale Video Resolution to Reduce AVI File Size

Typically, the higher the resolution is, the larger the AVI video size will be. So one of the most efficient ways to downsize AVI file is to reduce the video resolution. But this method will inevitably lead to a quality loss. So we suggest that you change video resolution from a high-quality video like 4K/2K/1080P so that the compressed video can still have a decent output quality.

GetGet this AVI video compressor and follow the steps.

Step 1: Launch the program and choose the Converter module. Then click the center + button to load files into the program.

Step 2: Unfold the right-side output format image and select the AVI format under the Video category or other formats as you like.

Step 3: Open the Parameter settings to change the Resolution under Video Settings. (e.g. from 1280x720 to 640x480) You can also head to the Quick setting below the Parameter settings and drag the sliders to your preferred resolution.

Step 4: Choose an output destination and press Run to start the AVI compression process.

Method 3. Reduce Video Bit Rate to Compress AVI Files

Video bitrate is also a crucial factor that affects the video file size. The lower the bitrate of the video is, the smaller the video size you will get. But this method also will degrade the video quality, so don’t make it too low or use this method with high bitrate video, otherwise, the image quality can be really bad.

InstallInstall the video size compressor and follow the how-to steps:

Step 1: Open HD Video Converter and select Converter to enter the main interface. Then follow the instruction on the main interface to load your AVI files into the program.

Step 2: Choose the original AVI video format or change it to another format by clicking the right-side output format image.

Step 3: Click the bottom compression button and drag the sliders to the right to set the compression ratio. (Note: The slider goes more right; the video is compressed smaller.) Alternatively, you can also open the Parameter settings and customize the specific video bitrate.

Step 4: Set the Output folder and press Run to start compressing AVI files.

Method 4. Lower Frame Rates to Downsize AVI Files

Another effective way to compress AVI files is to reduce the video frame rates. The video is smooth enough to play between 24~30 fps, the higher frame rates may be invisible to the human eyes. So if your video is shot in 50 fps or 60 fps, you can reduce the AVI file size by changing the frame rates to 24 fps or 30 fps. But note that frame rates dropped under 20 fps will cause visible inconsistency during the video playback.

Step 1: Run the software and open the Converter window. Then click the +Add files button to import the source AVI files into the program. You can also directly drag and drop the source videos into the program.

Step 2: Hit the right-side format image to open the output format list. Go to the Video category and select the original AVI format. You can also select other formats according to your actual needs.

Step 3: Open the Parameter settings window and head to the Frame rate under the Video Settings. Choose an option from the Frame rate drop-down list, or you can customize another specific frame rate.

Step 4: Specify a destination folder to keep the compressed AVI files and then press the Run button to start compression.
