What Compress AVIF is for
Use this tool to shrink an AVIF file while keeping the .avif format. It decodes the image and re-encodes it in your browser with a quality setting and optional max width, so nothing is uploaded.
- Shrink an AVIF file further by lowering quality or reducing dimensions.
- Hit a strict size limit while keeping the efficient AVIF format.
- Trim oversized AVIF exports before publishing them to the web.
- Recompress a batch of AVIF images at once.
Best practices for better results
Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.
- AVIF is already efficient, so small quality drops yield big savings.
- Quality around 50 to 60 keeps images clean at a small size.
- Reduce the dimensions if the image is larger than it needs to be.
- Keep the original if you might need full quality later.
What happens to your images?
When you choose a file, your browser reads it locally and creates the processed version on your own device. CompressImage.ca does not receive the original image or the finished file.
That local-first approach is useful for personal photos, client work, screenshots, documents, product images and other files you do not want to upload to a third-party server.
When to use another tool
The best tool depends on what you are trying to fix. Compression reduces file size, resizing changes dimensions, conversion changes format, cropping changes framing, and metadata removal cleans hidden information from the file.

Compress AVIF FAQ
How do I compress an AVIF file?
Drop your .avif files, lower the quality or set a max width, and download the smaller AVIF copies. Everything runs locally in your browser.
Does compressing AVIF lose quality?
AVIF uses lossy compression, so a lower quality setting means a smaller file with some detail loss. Higher quality keeps more detail at a larger size.
Why is AVIF already so small?
AVIF is one of the most efficient image formats, so files are already small. Compressing further helps when you need to hit a strict size limit or trim very large images.
Are my images uploaded?
No. AVIF is decoded and re-encoded entirely in your browser, so your images never leave your device.
