Which format to pick

Why WebP will not open

WebP is a format Google made for the web. Browsers show it fine, but older word processors and some upload forms do not recognise it. Converting to PNG or JPG usually solves it outright.

PNG versus JPG

PNG keeps the original pixels exactly and supports a transparent background. It suits logos, screenshots and diagrams.

JPG throws away detail the eye is least likely to notice, which shrinks the file a lot. It suits photographs, and any transparency is filled with white. The quality slider controls how much gets thrown away.

Common questions

Does quality drop?+

Not when converting to PNG. Converting to JPG discards detail in proportion to the quality setting, though above 90% it is hard to see.

My transparent image came out with a white background.+

JPG cannot store transparency, so white is filled in. Choose PNG or WebP to keep it.

What about HEIC and AVIF?+

AVIF converts if your browser can open it. HEIC works too. If iPhone photos are all you have, the HEIC converter is the easier route.

How many at once?+

They are processed one after another, so there is no set limit. Dozens of large photos will take a while and are heavy on a phone.
