Why convert JPG to WEBP
WEBP delivers 25-35% smaller files than JPG or PNG at comparable quality and supports transparency. All modern browsers (Chrome, Firefox, Safari, Edge) support it natively.
Privacy and processing
PNG, JPG, and WEBP conversions run entirely in your browser using the Canvas API. The image never uploads to a server, which keeps the operation fast and your file private.
JPG to WEBP online with ImgShifter
If your site serves photos as JPG, converting them to WEBP is the cheapest page-speed win available: same visual quality, roughly a quarter to a third fewer bytes per image, multiplied across every photo on every page. That's why Lighthouse and PageSpeed Insights flag JPG photos with a 'serve images in next-gen formats' warning - and this tool is the fix.
The conversion runs on your device using a WebAssembly build of libwebp. Drop one photo or a whole folder's worth: each JPG is decoded, re-encoded at a high WEBP quality setting, and offered back individually or as a ZIP. Since both formats are lossy, convert from originals rather than from copies that have already been recompressed by a chat app or CMS.
WEBP's one real limitation is life outside the browser - older desktop software and some email clients still don't read it. The practical pattern: keep JPG masters, serve WEBP on the web, and convert back only when a specific destination demands it. Everything here runs offline once the page loads.
