WebP2JPG (webptojpeg.vercel.app) is a free, browser-based tool that converts WebP image files to JPG format. It was built to solve a common friction point: websites increasingly serve images in the WebP format for performance reasons, but many everyday workflows — email, printing, form uploads, legacy software — still require JPG.
Most online image converters upload your file to a remote server, process it there, and send back the result. WebP2JPG takes a different approach: the entire conversion happens locally in your browser using the HTML5 Canvas API and the W3C FileReader API. Your image never leaves your device.
WebP2JPG is a static HTML/JavaScript application with no server-side backend. It uses three standard browser APIs: the FileReader API (W3C specification) to read the selected file, the Canvas API to decode and re-encode pixel data, and the Blob/Data URL API to trigger a file download. The source code can be inspected via your browser's developer tools — there is nothing hidden.
The project is maintained by Oscar Gabriel Mora López. Related tools and projects are available on GitHub (oscargml).
WebP2JPG does not collect, store, or transmit any image data. The only external requests the page makes are for Google Fonts (typography) and Google AdSense (advertising). No analytics SDKs, no tracking pixels, no session recording. See the full Privacy Policy for details.
