Frequently Asked Questions: JPG to WebP Conversion

How does converting JPG to WebP improve my SEO?
Google uses page load speed as a ranking factor. By converting JPG to WebP, you reduce image file size by up to 30%, which directly improves your Core Web Vitals (specifically LCP). Faster pages provide a better user experience, which leads to higher rankings in search results.
Is WebP compatible with all modern browsers?
Yes, WebP is supported by 96% of browsers, including Chrome, Safari, Firefox, and Edge. It is currently the industry standard for web image optimization. If you have legacy users, modern web servers can automatically serve the original JPG as a fallback while providing WebP to almost everyone else.
Will I lose image quality by switching to WebP?
WebP uses more advanced predictive coding than JPG, meaning it can achieve much smaller file sizes with the same visual quality. In most cases, the difference is invisible to the human eye, making it the most efficient way to optimize photos for web without compromises.

How does JPG to WebP conversion work?

JPG to WebP conversion uses modern predictive coding to achieve superior compression. While JPG treats each pixel block independently, WebP uses spatial prediction from neighboring blocks to represent visual data more efficiently. This technology is derived from the VP8 video codec, allowing it to reduce file sizes by up to 30% compared to JPG at the same visual quality level.

Our tool performs this optimization entirely in your browser using WebAssembly. This means that instead of uploading your photos to a distant server, the conversion happens on your own hardware. This approach is not only faster for real-time processing but also ensures absolute privacy and security for your personal or professional images.
