Frequently asked questions
Does converting JPG to PNG improve quality?
No. It keeps exactly the pixels that are already in the JPG, including any compression artifacts. It stops further quality loss if you edit and save the image several times.
Why is the PNG so much bigger?
PNG stores every pixel without lossy compression, which is inefficient for photos. Expect the file to grow several times; the result card shows by how much.
Can the PNG have a transparent background?
Not automatically. A JPG has no transparency to carry over; use the background remover first if you need a transparent PNG.
Is there a file size limit?
There is no fixed limit, but very large photos use a lot of memory in the browser. Phones may struggle above roughly 50 megapixels.
Are my photos uploaded?
No. Everything happens in this browser tab.
