Convert JPG to WebP: next-gen images for the web
WebP is the modern image format recommended by tools like Google PageSpeed Insights ("Serve images in next-gen formats"). Google's own comparison found WebP photos about 25–34% smaller than JPGs of the same visual quality, which means faster pages, less mobile data and better Core Web Vitals.
Convert a whole folder of JPG photos in one go, with full resolution kept and a quality slider to fine-tune the result; 80–85% is a strong default for websites. Pair it with SEO-friendly file names when you upload to WordPress, Shopify or a static site.
Converted in your browser, never uploaded
Every conversion runs inside your browser. Images are read from your device into memory (RAM), decoded, redrawn on an HTML5 canvas and saved straight to your downloads, so personal photos never touch a server, are never stored and cannot be seen by anyone else. There is no upload wait, no file-count limit and no watermark. Converted files keep their full resolution; camera metadata such as GPS location is not copied into the new file.
Frequently asked questions
Will converting JPG to WebP ruin my image quality?
No. At 80% quality and above, WebP photos look the same as the JPG at normal viewing size while being noticeably smaller. Converting a JPG does not add new loss you can see at these settings.
Can every browser show WebP images?
All current versions of Chrome, Edge, Firefox, Safari and Opera display WebP, on desktop and mobile. Only very old browsers, such as Internet Explorer, cannot.
Should I convert every JPG on my website to WebP?
For images shown on your own website, usually yes. Keep JPG copies for email, printing and platforms that do not accept WebP, such as some marketplaces.
