Change format, resize and recompress your images — all in your browser.
JPG is best for photographs: small files, no transparency. PNG is lossless and keeps transparency, ideal for logos, screenshots and graphics with sharp edges. WebP usually beats both on size at the same quality and supports transparency, which makes it great for the web when you don't need to support very old browsers.
Most "online image converter" sites upload your pictures to their servers. This one doesn't. The conversion happens inside your browser tab using the HTML canvas, so your images never touch the network — nothing to leak, cache, or delete later.
Yes. There is no upload step and no account. You can open your browser's network tab and watch: no request carries your image data. The tool works offline once the page has loaded.
Converting to a lossless format like PNG preserves every pixel. Converting to JPG or WebP is lossy — the quality slider trades file size against fidelity. Note that resizing down and back up cannot recover detail, so keep your originals.
The JPG format has no transparency channel, so transparent areas are flattened onto a white background. Export to PNG or WebP if you need to keep transparency.
