Convert PNG to JPG
JPG files are far smaller than PNG for photographs. JPG has no transparency, so any transparent areas are filled with white during conversion.

When to convert PNG to JPG
Much smaller photos
For photographic content JPG is typically a fraction of the PNG size at a quality difference most people cannot see.
Wider compatibility
Some older systems, printers and upload forms accept JPG only.
Meeting an upload size limit
Application forms often cap uploads at a few hundred KB, which a PNG photo will usually exceed.
Where the conversion happens
This converter runs in your browser using its built-in image support. Your file is read from disk, converted, and offered back for download — in the normal case it never leaves your device, so there is nothing for us to store, and the conversion works the same whether the file is 50 KB or 50 MB.
Very large images can exceed what a browser tab can safely decode. If that happens, or if your browser cannot produce JPG files, CurePDF will say so and offer to process the image on our servers instead — but only after you explicitly agree. Nothing is uploaded before you choose that.
Frequently asked questions about PNG to JPG
What happens to transparent areas when I convert PNG to JPG?
They are filled with white, because JPEG has no alpha channel and there is nowhere for transparency to go. If keeping a transparent background matters, convert PNG to WebP instead — WebP stores transparency and is smaller than PNG.
What quality does the JPG use?
92%. High enough that the re-encoding is hard to spot at normal viewing size, while still cutting the file size substantially for photographic content.
Will screenshots or images with text look worse as JPG?
Often yes. JPEG compresses smooth gradients well but leaves faint halos around hard edges, which is exactly what text and flat-colour graphics are made of. For those, staying with PNG usually looks better and may even be the smaller file.
Can I convert the JPG back to PNG later with no loss?
You can convert it back, but it will not undo anything. You would get a lossless copy of an image that has already been through JPEG compression.
Are the dimensions or metadata affected?
The width and height are unchanged. Metadata such as camera model and GPS coordinates is not carried into the JPG.
