What converting to PNG does, and does not do

PNG is lossless, so from this point on the picture is saved without any further compression — useful when you will edit it and save it again. It cannot restore detail the JPEG already threw away, and a photograph as a PNG is usually several times larger.

A JPEG has no transparency, so the PNG will not either; the background stays as it was.

Going smaller instead?

If the goal is a smaller file, PNG is the wrong direction. Compress the image or convert it to WebP instead.

If the image is larger than you need, set a maximum width or height in the settings form at the same time: a smaller PNG keeps all of PNG’s benefits at a fraction of the size. The conversion happens in your browser, so the photo is never uploaded anywhere.

Questions

JPG to PNG: common questions

Will the PNG look better than the JPG?

No. It is an exact copy of the JPEG’s pixels, artefacts included; it simply stops new ones from being added.

Why is the PNG so much bigger?

Lossless compression keeps every pixel, and photographs have a lot of them that differ. That is the trade for no further quality loss.

Is my image uploaded?

No. Your browser converts it on your device.
