JPG to PNG

Let's be clear about what this conversion does not do: it does not improve your image. The compression loss already in the JPG stays exactly where it is, and the PNG will almost always be larger than the original. So why convert? Because some systems, templates and upload forms require PNG, and because PNG is a sensible working format when you are going to edit an image several times. Every time you save a JPG it is compressed again; a PNG can be saved over and over without adding new artifacts.

There is another good reason: preparing an image for transparency. JPG cannot store transparent areas, so if you plan to remove the background in an editor, starting from a PNG saves one conversion later. Keep in mind that the conversion itself does not remove anything: the result is still a rectangular image with its original background. If all you want is to share, upload or send the photo, stay with the JPG, since it is smaller and accepted everywhere.

The quality setting decides what kind of PNG you get. At 99, Pikkx writes a lossless truecolor PNG: every pixel of the JPG is kept as is, and that is what you want for photos and for editing. Below 99, it writes a palette PNG, much lighter but reduced to a limited set of colors. That works for simple graphics saved as JPG, like a diagram or a logo, but on a photo it can cause banding in gradients. Check the before and after size of each file.

Drag in up to 10 JPG files, 5 MB each, keep the quality at 99 for photos (it starts there) and download the PNGs individually or together in a ZIP. The dimensions do not change unless you select a size. Because the PNG is rebuilt from the pixels, the EXIF data in the JPG, including GPS location and date taken, is not kept. That is useful before sharing an image publicly, but if you need those details, keep the original file.
