# Compress AVI

> Compress Audio Video Interleave (AVI) files online for free. The compressor re-encodes the video at a lower bitrate. Runs in your browser, so your files never leave your device. Or set an exact target size.

- Compression: lossy, runs in the browser (nothing is uploaded).
- API: `POST /api/v1/jobs` with `"operation": "compress"` and an optional `compression_level` or `target_size` (paid plans).
- Format: [AVI converter](https://www.converterrr.com/avi-converter), [Compress videos](https://www.converterrr.com/compress-videos).

## What compression does to AVI

Re-encodes the video at a lower bitrate.

- **Light:** Near-lossless: re-encodes conservatively and keeps the full resolution.
- **Balanced (default):** The default: looks the same for most uses, and typically 40–70% smaller.
- **Strong:** Smallest file: lower quality, and large videos are downscaled.

Need it much smaller? MP4 is smaller for the same quality and plays everywhere. [Convert AVI to MP4](https://www.converterrr.com/avi-to-mp4).

## Need an exact size?

Set a target size or a percentage to reduce by. These pages preset common video sizes and take AVI too:

- [Compress video to 8 MB](https://www.converterrr.com/compress-video-to-8mb): Chat app uploads
- [Compress video to 10 MB](https://www.converterrr.com/compress-video-to-10mb): 10 MB upload limits
- [Compress video to 25 MB](https://www.converterrr.com/compress-video-to-25mb): Email attachments
- [Compress video to 50 MB](https://www.converterrr.com/compress-video-to-50mb): Portals & bigger uploads
- [Compress video to 100 MB](https://www.converterrr.com/compress-video-to-100mb): Long videos, smaller

## How to compress AVI

1. **Add your AVI files.** Drag and drop AVI files onto the compressor, paste them, or click to browse. You can add several at once.
2. **Pick a level or a target.** Balanced is selected and suits most files. Choose Light to stay closer to the original or Strong for the smallest file, or set a target size or a percentage to reduce by.
3. **Compress.** Click Compress. Your AVI files are processed right in your browser, usually in seconds.
4. **Download.** Download each smaller AVI, or everything at once as a ZIP.

## Good to know

- AVIs are often recorded with older, less efficient codecs or barely compressed at all, so re-encoding at a lower bitrate tends to save a lot.
- AVI compression runs on FFmpeg in your browser, which is slower than hardware encoding, so long files take a while. For phones and the web, converting AVI to MP4 is usually the better move.
- Need to meet an upload limit? Set a target size (or a percentage to reduce by) in the compressor and the video is compressed to fit.
- AVI compression runs entirely in your browser with WebAssembly, so nothing is uploaded and your files never leave your device.

## About the AVI format

AVI is Microsoft's classic video container from 1992. It's still found on older cameras and archives but lacks modern features.

## Compressing AVI: frequently asked questions

### How do I compress an AVI file?

Drop the AVI onto the compressor above, keep Balanced or pick another level, and click Compress. Download the smaller AVI when it's done; it usually takes a few seconds.

### Does compressing AVI reduce quality?

A little, by design: AVI is a lossy format. Balanced is tuned to look the same for most uses; choose Light if you want to stay closer to the original.

### How much smaller will my AVI get?

Usually a lot, because AVI files often use dated codecs or very high bitrates.

### Can I compress AVI to a specific size?

Yes. Set a target size in the compressor, or a percentage to reduce by, and the file is compressed to land at or just under it.

### Is it safe to compress AVI files here?

Yes. AVI files are compressed inside your browser with WebAssembly and never uploaded to a server.

### Is the AVI compressor free?

Yes. Compression is free with no watermark and no sign-up, within the same daily allowance as conversions.

### Should I convert my AVI instead?

Sometimes. MP4 is smaller for the same quality and plays everywhere. The AVI to MP4 converter does that in one step.
