    常见问题

    Are my pictures uploaded?

    No. Each picture is decoded and re-encoded inside this page, on your own device. Nothing is sent to a server, so no copy is kept anywhere.

    What happens to transparency when I convert to JPG?

    JPG cannot store transparency, so anything see-through is filled with the background colour you choose — white by default. Convert to PNG or WebP instead when the transparency matters.

    Does converting PNG to JPG lose quality?

    Yes, a little. PNG is lossless and JPG is not, so some detail is thrown away to make the file smaller. For a photograph that is a good trade; for a screenshot, logo or anything with sharp text, stay with PNG or use WebP, which does both.
