What is AVIF compression?
AVIF compression reduces the file size of AVIF images so they load faster on websites, apps and modern digital platforms. AVIF is a modern image format known for strong compression, but large AVIF files can still slow down pages or become difficult to upload on platforms with file size limits.
This AVIF compressor is built for quick browser-based use. You can upload an AVIF image, choose compression quality, set a maximum width or enter a target KB size. The tool then creates a smaller version that you can download instantly.
When should you compress AVIF images?
Website performance
Compress AVIF images before using them in hero sections, galleries, blog posts, landing pages or product pages.
App assets
Reduce AVIF file size before adding images to apps, UI screens, onboarding flows or media-heavy layouts.
SEO and Core Web Vitals
Smaller images can help pages load faster, especially on mobile connections.
Upload limits
Some platforms reject large image files. Compressing AVIF can help meet size limits such as 100KB, 200KB or 500KB.
Best settings for AVIF compression
For websites
Use medium to high quality and resize very large images to a practical width such as 1280px or 1920px.
For strict upload limits
Enter a target KB size first. If the file is still large, reduce max width and try again.
For quality
Keep quality higher and avoid unnecessary resizing if the image already has reasonable dimensions.
AVIF browser support note
AVIF compression depends on your browser’s ability to decode and process AVIF images. If your AVIF image does not open or compress, try another updated browser or use a more widely supported format such as WebP or JPG.
