Questions and answers
Does JPG to PNG make the background transparent?
No. PNG can store transparency, but converting does not remove the background: the image looks exactly the same, now in PNG.
Why is the PNG bigger than the JPG?
PNG is lossless, so it stores every pixel exactly. Photos saved as PNG are often 3 to 6 times larger than the JPG.
Are my images uploaded anywhere?
No. The conversion happens inside your browser with your device’s own processor. Nothing is sent to a server, so it also works with private photos.
Is there a limit on files?
There is no daily limit. You can add many files at once; very large photos (over about 50 megapixels) may be slow on older phones.
