## What compression does to AVIF

Re-encodes AVIF (AV1) at a tuned quality.

- **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 images are downscaled.

## Need an exact size?

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

- [Compress image to 20 KB](https://www.converterrr.com/compress-image-to-20kb): Signatures & tiny photos
- [Compress image to 50 KB](https://www.converterrr.com/compress-image-to-50kb): ID photos & form uploads
- [Compress image to 100 KB](https://www.converterrr.com/compress-image-to-100kb): 100 KB upload limits
- [Compress image to 200 KB](https://www.converterrr.com/compress-image-to-200kb): Web images & listings
- [Compress image to 300 KB](https://www.converterrr.com/compress-image-to-300kb): Larger web images

## How to compress AVIF

1. **Add your AVIF files.** Drag and drop AVIF 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 AVIF files are processed right in your browser, usually in seconds.
4. **Download.** Download each smaller AVIF, or everything at once as a ZIP.

## Good to know

- AVIF uses the AV1 codec and is one of the most efficient image formats there is, so a file that's already AVIF has less to trim than a JPG or PNG.
- AVIF encoding is compute-heavy: large images can take a few seconds to compress in the browser.
- Need to meet an upload limit? Set a target size (or a percentage to reduce by) in the compressor and the image is compressed to fit, downscaling it if it has to.
- AVIF compression runs entirely in your browser with WebAssembly, so nothing is uploaded and your files never leave your device.

## About the AVIF format

## Compressing AVIF: frequently asked questions

### How do I compress an AVIF file?

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

### Does compressing AVIF reduce quality?

A little, by design: AVIF 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 AVIF get?

AVIFs are usually compact already. Expect smaller gains than with JPG or PNG unless the original was saved at very high quality.

### Can I compress AVIF 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 AVIF files here?

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

### Is the AVIF compressor free?

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