Tools / File Converter / PNG to JPG
Turn large PNGs into small JPGs and pick a colour for transparent areas.
PNG is lossless, so screenshots and photos saved as PNG end up much larger than they need to be. The same photo as a JPG is often 5–10 times smaller. This tool converts PNGs to JPG.
If your PNG has transparent areas, they are filled with a colour, because JPG has no transparency. White is the default, but you can pick any colour.
Usually not. JPG adds slight blur around text and flat colours. Keep such images as PNG or convert them to WEBP.
80–90% is a very good balance for photos. Going above 95% makes the file bigger without a visible difference.
Inside your browser. PNG to JPG uses the browser’s own encoder, and no file is sent to a server.
