Why convert JPG to PNG?
PNG is a lossless format, so it preserves every pixel without the compression artefacts that JPG can introduce around text and sharp edges. Converting JPG to PNG is the right move when you need clean edges for a logo or graphic, a format that supports transparency, or a source image you will edit further without losing quality each time you save.
Make the background transparent
JPG files cannot store transparency, but PNG can. If your image is a logo, product shot, signature or icon on a solid background, switch the Background option to "Remove background" and the tool will detect the background color from the edges of your image and make it see-through as it exports the PNG. You can also pick the color manually, and use the tolerance slider to control how much is removed. This works best on a clean, solid-color background.
