About PNG to JPG
PNG to JPG turns a PNG image into a JPG file. JPG has no transparency, so the page asks which color the transparent areas should become (white at first) and paints it under the image before encoding. The "JPG quality" slider, from 10 to 100, sets how much detail the compression keeps; it starts at 92. An animated PNG gives its first frame only, and the page says so before you convert. Several PNGs can be converted at once, one after the other, with the same settings. The JPG is encoded in your browser; for very large images on an iPhone or iPad, by MozJPEG in WebAssembly.
How to convert PNG to JPG
- 1Choose the PNG to flatten, or several at once; one image appears in the upload area, several are counted there.
- 2Set the "JPG quality" slider.
- 3Next to "Transparent areas become", pick the color for the transparent parts.
- 4Click "Convert", then "Download" to get the JPG with the PNG's name. With several images, each JPG has its own button, and the button above the list saves them all in one ZIP.

Where your file is processed
Conversion happens inside this tab: the browser decodes the PNG, fills the transparent areas, and writes the JPG. The image is never transferred to a server. If an error appears, a cleaned report (message, tool name, browser name, and version) is logged so that we can fix problems.
Frequently asked questions
Can I choose the color of the transparent parts?
Yes. They take the color chosen next to "Transparent areas become", white unless you change it. Half-transparent edges are blended with that color, so pick the color of the page or document the JPG will sit on.
Will I lose quality converting PNG to JPG?
Yes, some. JPG is lossy, so fine detail and sharp edges get slightly blurred. The slider starts at 92; lower values make a smaller file with more visible artifacts.
Can I convert many PNG files at once?
Yes, up to 30 images at a time: choose or drop them together. They are converted one after the other with the same quality and background color; an image that cannot be read gets its own message and the others are still converted. Each JPG has its own Download button, and the button above the list saves them all in one ZIP.
Tips and tricks
- ✓To keep the transparency in a smaller file, convert with PNG to WebP instead: WebP has an alpha channel.
