Why Convert AVIF to WEBP
WebP produces files that are 25-35% smaller than equivalent JPG images at the same visual quality. Switching to WebP can save gigabytes of bandwidth for image-heavy websites.
Unlike JPG, WebP supports alpha transparency like PNG and frame-based animation like GIF — all in a single format. One file type handles photos, graphics, and short animations.
Google developed WebP specifically for web performance. Smaller image files mean faster page loads, improved Core Web Vitals scores, and better search engine rankings for your website.
WebP offers both lossy compression for photos and lossless compression for graphics, letting you choose the right balance between file size and quality for each individual image.
Chrome, Firefox, Safari, Edge, and all modern mobile browsers now support WebP natively. Over 97% of web users can view WebP images without any compatibility issues.

About the AVIF Format
AVIF (AV1 Image File Format) is a next-generation image format based on the open-source AV1 video codec, standardized in 2019 by the Alliance for Open Media. It delivers exceptional compression efficiency — typically 20-30% better than WebP and up to 50% better than JPEG at equivalent visual quality. AVIF supports both lossy and lossless compression, making it one of the most versatile modern image formats available.
AVIF is designed for the next era of web imagery, supporting features like HDR (High Dynamic Range), wide colour gamuts with 12-bit depth, and full transparency. Browser support has been growing steadily, with Chrome, Firefox, and Safari 16+ all providing native AVIF rendering. The primary trade-off is encoding speed — AVIF images take significantly longer to compress than JPEG or WebP, which can be a bottleneck for real-time image processing pipelines and high-volume workflows.
