    Why convert JPG to PNG?

    People convert JPG to PNG for a few practical reasons. PNG is a lossless format, so once your image is a PNG you can open, edit and re-save it repeatedly without the generation-loss that plagues JPG — every JPG save throws away a little more detail, while PNG keeps things pixel-perfect. PNG is also the format many design tools, documentation systems and app stores expect for screenshots, icons and graphics, and it is the go-to when you plan to add transparency later in an editor. It is worth being honest about one thing: converting a JPG to PNG does not undo the compression that already happened. The blocky artefacts and softened detail baked into the JPG are permanent, and PNG simply preserves them faithfully. You should also expect the file to get larger, sometimes several times larger, because PNG does not use the aggressive compression JPG relies on for photographs. That trade-off is exactly the point — you are choosing a stable, lossless container over a small one. The whole conversion happens on the HTML canvas inside your browser, so your photos are never uploaded and there is no account, watermark or waiting.

    FAQ

    Does converting to PNG improve the image quality?

    No. PNG cannot recover detail already lost to JPG compression. It preserves the image exactly as it is, artefacts and all, in a lossless container.

    Why is the PNG bigger than the original JPG?

    PNG stores photographic data without lossy compression, so for photos it is usually several times larger than the JPG. That is normal and expected.

    When should I choose PNG over JPG?

    Choose PNG when you need lossless editing, sharp screenshots and graphics, or a format that a tool specifically requires. Keep JPG for small photo files.

    Are my images uploaded?

    No. Conversion runs locally in your browser with the canvas API. Your JPG files never leave your device.
