Convert PNG images to JPG, with transparency flattened to white.

About the PNG to JPG Converter

PNG and JPG solve different problems — PNG for lossless quality and transparency, JPG for smaller file sizes on photographic content — and converting between them is a routine need whenever a form, upload widget, or print service insists on one format over the other. This tool converts your PNG to JPG in one click.

Because JPG has no concept of transparency, any transparent areas in your PNG are flattened onto a white background before conversion — the standard, expected behaviour for this conversion. If your PNG has no transparency (most photos and flattened graphics don't), the conversion changes nothing but the file format and typically shrinks the file noticeably, since JPG's compression is usually far more efficient than PNG's for photographic content.

Common reasons to convert: a website or ad platform that only accepts JPG uploads, an email attachment size limit that a losslessly-compressed PNG blows past, or simply wanting a smaller file for a photo where perfect pixel fidelity doesn't matter. Conversion runs entirely in your browser — your image is never uploaded.

One thing to check before converting: if your PNG has meaningful transparent regions (a logo meant to sit over a coloured background, an icon with rounded corners), converting to JPG will bake in a solid white background permanently — there's no getting the transparency back afterward. Keep the original PNG safely stored if you might need the transparent version again later.

Frequently asked questions

What happens to transparent areas?
They're filled with white, since JPG doesn't support transparency. If you need to preserve transparency, keep the file as PNG or use a format like WebP that supports both.
Will the file get smaller?
Usually yes, often significantly — JPG's lossy compression is typically far more space-efficient than PNG's lossless compression for photographic content, though PNG can be smaller for simple graphics with large flat colour areas.
Does converting lose image quality?
JPG uses lossy compression, so there is some quality loss compared to the lossless PNG source — usually imperceptible at normal viewing sizes, more visible if you zoom in closely or the image has fine text/line detail.
