About This Tool
WEBP is Google's modern image format designed for the web. Released in 2010 and now supported by every major browser, WEBP should be the default image format for any website built in the 2020s.
The efficiency advantage over JPEG is significant and consistent. Photographs, illustrations, screenshots, and diagrams all compress more efficiently in WEBP. At equivalent quality, WEBP files are 25–35% smaller — meaning faster page loads, lower bandwidth costs, and better Core Web Vitals scores.
Unlike JPEG, WEBP supports transparency (alpha channel). This makes it suitable for logos, icons, and product cutouts previously requiring PNG — at dramatically smaller file sizes. A 200KB transparent PNG logo might become 30–50KB as WEBP.
SiteConversor converts any common image format to WEBP using the browser's native Canvas API. The conversion is instant because it happens locally — no upload, no waiting, no server round-trips.
Frequently Asked Questions
Why use WEBP instead of JPG? expand_more
WEBP achieves 25–35% better compression than JPG at equivalent visual quality. For websites, this means faster loads, better Core Web Vitals, and improved Google search rankings.
Does every browser support WEBP? expand_more
Yes, since 2020. Chrome, Firefox, Safari 14+, Edge, and Opera all support WEBP. Legacy IE support is effectively zero — no fallback needed for modern sites.
Can WEBP have transparent backgrounds? expand_more
Yes. WEBP supports full alpha transparency like PNG, but at much smaller file sizes. Ideal for logos, icons, and UI elements.
WEBP vs AVIF: which is better? expand_more
AVIF achieves even better compression (15–20% smaller than WEBP) but encoding is more CPU-intensive and support is less universal. WEBP is the best current balance of efficiency and compatibility.
Can I convert back from WEBP to JPG? expand_more
Yes — use our Convert Image tool and select JPG as output. Note that WEBP→JPG is lossy since JPG doesn't support transparency.
