How to convert JPG to PNG
1. Drop one or more JPG files. PNG and WebP are refused here. 2. Press “Convert images”. 3. Download the PNG files, or a ZIP when you converted several.
PNG does not add detail that the JPG already threw away. It only stores the pixels you have without a second round of JPEG compression. The file is often larger than the JPG.
When PNG is the right output
Use it for an editor, a slide tool or a form that rejects JPG, and when you will edit the picture again and do not want more JPEG blocks. For a smaller photo to send in chat, keep JPG or convert to WebP on Convert image.
What stays and what goes
Width and height stay the same. Camera location is not copied, because the file is redrawn on the canvas. A JPG never had a transparent background, so the PNG will not invent one.
