Before you get started

How do I convert PNG to JPG?

Choose the PNG pictures above, keep JPG selected and press Convert images. Transparent backgrounds turn white, which most forms and websites expect.

How do I convert WebP to JPG?

Choose the WebP files, keep JPG selected and convert. This is useful when a website saved a picture as WebP and an app or form only accepts JPG.

Does converting reduce quality?

JPG and WebP are saved at high quality, so the change is hard to see. PNG is lossless. To reach a size in KB, use Compress image instead.

Can I convert many pictures at once?

Yes. Choose them together; they are converted in one go and downloaded as a ZIP with the original names.
