Convert PNG to JPG, Entirely in Your Browser
This tool never sends your image anywhere — the conversion happens locally using your browser's built-in Canvas API, the same technology web pages use to draw graphics. Your PNG is read directly from your device, drawn onto a canvas, and re-exported as a JPG, all without a network request. That makes it fast, private, and usable offline once the page has loaded.
JPG doesn't support transparency the way PNG does, so any transparent areas in your PNG are filled with solid black before conversion. If your PNG has transparent regions you want to keep a specific color, flatten it onto that color before converting, since JPG has no way to represent transparency itself.
Why convert PNG to JPG?
JPG files are typically much smaller than PNG for photographs and complex images with lots of color gradients, since JPG uses lossy compression tuned for photographic detail. PNG is the better choice for screenshots, logos, and images with sharp edges or text, where JPG's compression can introduce visible artifacts. If file size matters more than pixel-perfect edges — for a web page, an email attachment, or a photo gallery — JPG is usually the right call.
What does the quality slider do?
JPG compression is adjustable: a higher quality setting keeps more visual detail at the cost of a larger file, while a lower setting shrinks the file further but can introduce visible blockiness, especially around sharp edges or text. The slider defaults to 90%, a good balance for most photos — drag it down if file size matters more than perfect detail, or up if you're archiving something you don't want compressed further.
Is there a file size or dimension limit?
Not from this tool specifically — since conversion happens in your own browser rather than on a server, the practical limit is your device's available memory rather than any limit we impose. Very large images (tens of megapixels) may take a moment longer to process or use more memory than a phone or older computer has available, but there's no artificial cap on file size or dimensions.
