What this tool does

AVIF is the next-generation image format offering significantly smaller file sizes than WebP and JPEG at equivalent quality. PixelForge lets you convert your entire image library to AVIF in a single batch — ideal for developers optimizing web performance and Core Web Vitals scores. All major browsers now support AVIF.

Problems it solves

  • Converting a product catalog to AVIF for maximum web performance
  • Reducing image payload size for a web app or e-commerce site
  • Preparing images for modern browsers that support AVIF natively
  • Replacing WebP images with AVIF for an additional 20–50% size reduction

Example

Frequently asked questions

How much smaller are AVIF files compared to JPEG and WebP?

AVIF is typically 30–50% smaller than JPEG and 20–30% smaller than WebP at equivalent perceptual quality. The exact savings depend on image content — photos with smooth gradients benefit most.

Is AVIF supported in all browsers?

AVIF is supported in Chrome, Firefox, Safari (15.4+), and Edge. For older browser compatibility, serve AVIF with a WebP fallback using a <picture> element.

Is AVIF conversion slower than JPEG or WebP?

Yes — AVIF encoding is computationally more intensive than JPEG or WebP. Conversion may take longer, especially for large batches. PixelForge processes images server-side, so this doesn't affect your device.

Can I convert AVIF back to JPG or PNG?

Yes — use the Bulk Image Convert tool and select JPEG or PNG as the target format. PixelForge can read AVIF files as input.
