How to use the PNG to JPG Converter
- Add your file: drag it in, click the box, or paste it.
- Adjust the options if you want to.
- Download or copy the result.
JPG has no transparency, so transparent areas become white. We fill them with white so you never get a black background. Lower the quality slider to shrink the file further.
