Perkforge
How it works
Choose or drop a PNG, set the JPG quality and select the color used behind transparent pixels. Then convert and download. Nothing is uploaded and no account is required.
Useful to know
JPG does not support transparency. Transparent areas are flattened onto your selected background and higher quality usually creates a larger file.
Private by design
Inputs, selected files and results stay inside your browser. Perkforge does not receive the content you process with this tool.
