About this tool

Why compress images to AVIF?

AVIF is the most efficient image format browsers support today. At identical visual quality, AVIF files typically run 50–70% smaller than JPEG and 20–30% smaller than WebP — which means faster page loads, better Core Web Vitals scores, and lower bandwidth costs, all without a visible drop in image quality.

Faster load times

Smaller images mean your Largest Contentful Paint score improves — a key Core Web Vitals metric Google uses to rank pages.

No quality compromise

AVIF's compression algorithm preserves fine detail and gradients better than older formats, even at aggressive compression levels.

Universal browser support

Every major browser — Chrome, Firefox, Safari, Edge — supports AVIF natively as of 2024, making it safe to use in production today.

Tips for the best results

Resize before compressingDon't ship a 4000px photo at 400px display size — resize first, then compress for the biggest size reduction.
Use the comparison sliderDrag to compare original vs. compressed before downloading, so you never ship a quality you can't see in advance.
Batch your image folderDrop multiple images at once and download them all as a single ZIP when you're optimizing a whole gallery.
Keep a JPEG fallbackFor the rare visitor on a legacy browser, pair AVIF with a JPEG fallback using the <picture> element.
