What happens to transparency when converting PNG to JPG?

JPG doesn't support transparency, so transparent areas are filled with a background colour. It is white by default and you can pick any colour before converting.

Why convert PNG to JPG?

JPG files are typically much smaller than PNG for photographic images, saving storage and bandwidth.

Is this conversion private?

Yes, everything happens locally in your browser — no files are ever uploaded.

What color fills in where my PNG was transparent?

White by default. Use the Background control to choose black, grey or any custom colour; transparent and semi-transparent pixels are blended onto it before saving.

Will text or line art in my PNG look blurry as a JPG?

It can. JPG's compression is tuned for photographic gradients, and it tends to introduce soft artifacts around sharp edges like text or hard-edged graphics. For crisp graphics, PNG or WebP usually holds up better.

Does converting to JPG remove the color profile from my PNG?

The conversion re-encodes pixel data through the canvas, which normalizes color to standard sRGB. If your PNG carried a wide-gamut or custom ICC profile, that specific profile isn't preserved in the JPG output.

Why is my converted JPG file bigger than expected?

The quality slider defaults to 90%, which favors visual fidelity over file size. Lower the quality setting for a smaller file, or run the result through the image compressor for further savings.
