WebP2JPG (webpto.xyz) 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).
