How it works
WebP is an image format created by Google in 2010, designed to replace both JPEG and PNG on the web. It uses predictive coding derived from the VP8 video codec, which enables 25–34% smaller file sizes than JPEG at equivalent visual quality. WebP also supports transparency (like PNG) and animation (like GIF), making it a versatile all-in-one format for web developers.
While WebP has gained widespread browser support — Chrome, Firefox, Edge, and Safari 14+ all render it natively — it remains problematic outside the browser. Desktop applications like older versions of Photoshop, Microsoft Office, and many email clients cannot open WebP files. Social media platforms occasionally reject WebP uploads, and print shops almost universally require JPEG or TIFF.
Quick & easyPrivacy & security
WebP-to-JPG conversion runs entirely inside your browser using the native Canvas API. Your images are drawn onto an in-memory canvas, exported as JPEG, and made available for download — all without a single byte leaving your device. No server, no cloud storage, no analytics on your files.
This means you can safely convert confidential images — internal screenshots, medical records, private photos — without worrying about third-party access. The conversion works even offline once the page has loaded. When you close or refresh the tab, all image data is purged from browser memory.
