About JPG to PNG
Convert JPG or JPEG images to PNG, the lossless format that's perfect for editing, screenshots, and graphics that need crisp edges. PNG won't add new compression artifacts, so the image you get is a clean raster copy ready for further work.
The whole conversion runs locally with WebAssembly codecs in your browser. Your photo never touches a server — it's decoded and re-encoded entirely on your device.
