Pufomi is a free set of browser tools for converting, compressing, and resizing pictures. It handles formats like JPEG, PNG, WebP, GIF, and HEIC. The key difference from most online tools is that nothing gets uploaded - all processing happens locally on your device, so it's fast and completely private. No account, no sign-up, no watermarks. Works on any device with a modern browser, even offline once the page has loaded.
