Convert JPG to PNG
For an upload form that insists on PNG, or for a lossless copy before you start editing. The dimensions and the picture stay exactly as they were.
How to use it
Drop the JPG in
Drag it over or click to choose.
Nothing to set
PNG is a lossless format: there is nothing to throw away, so there is no quality setting either. The result is prepared straight away.
Download the PNG
Same pixel dimensions, same picture. The file size does grow — the reason is below.
An honest warning: PNG does not bring quality back
“PNG is higher quality”
PNG is lossless, but it is lossless for the picture it is handed. The detail thrown away when the file became a JPG is long gone; PNG does not bring it back, it only keeps what is left faithfully.
Bigger file, same picture
On a photograph, the PNG takes several times the space of the JPG. In return you gain nothing visually. Do not convert just to “make it better”.
Everything after this point is lossless
The benefit points forward: open and save a PNG as often as you like and no new loss piles up. If you are going to work on the file, this is the right intermediate format.
When you actually need it
The form asks for PNG
Some upload forms, print systems and design tools accept nothing else. This is the most common reason of all.
You are adding transparency
If you are about to erase the background or lay a transparent layer on top, the output has to be PNG anyway.
Editing in several passes
If you will open and save the same file over and over, a JPG degrades a little each round; a PNG does not.
You are only sharing it
Email, messaging, social media — JPG is both enough and far smaller.
Common questions
Does converting to PNG make the background transparent?
No. PNG can carry transparency, but a JPG has none to begin with — converting does not create it. To actually remove the background, use Background Remover.
Why did the file get so much bigger?
That is expected: PNG stores every pixel. On photographs a 3–8× increase is normal. If size matters, you are better off staying with JPG.
Do the JPG compression marks survive in the PNG?
They do. The blocky artefacts JPG leaves behind have become part of the picture, and PNG keeps those faithfully too. If you want to soften them, Image Upscaler can help.
Does the resolution change?
No, it stays exactly the same. If you want to change the dimensions as well, use Resize Image.
