WebP and AVIF are widely considered the best formats for SEO. They offer superior compression (smaller file sizes) compared to JPEG and PNG without sacrificing quality. Faster loading images improve your Core Web Vitals and search rankings.

We support the extensive range of modern web formats including JPEG (JPG), PNG, WebP, AVIF, and GIF. You can even convert formats during compression—for example, uploading a large PNG and saving it as an ultra-efficient AVIF file to save up to 90% storage space.

AVIF (AV1 Image File Format) is the next-generation standard that offers superior compression. It typically produces files that are 30-50% smaller than WebP and significantly smaller than JPEG for the same image quality. It provides the highest quality-to-size ratio available on the web today.

You can compress high-resolution photos (e.g., 50MB+ RAW exports) provided your device has enough memory (RAM) to handle the processing. This makes it ideal for professional photographers and designers.

Unoptimized images often account for 60-80% of a page's total weight. By reducing image size, you significantly improve your Largest Contentful Paint (LCP) score, a key Google Core Web Vital. Faster loading sites result in higher SEO rankings, lower bounce rates, and better user engagement.
