PNG and JPG solve different problems. PNG stores every pixel exactly as it was saved and supports transparency; JPG throws away detail the eye is unlikely to notice in order to make the file much smaller, and it has no transparency at all. Converting is worth doing when the image is photographic and the size matters — and worth avoiding when the image is a screenshot full of text or needs a transparent background.
JPG has no alpha channel. Any transparent area in your PNG has to become a solid colour, which is why logos exported as JPG often end up on an unexpected white or black box. If you need the background to stay transparent, keep the file as PNG.
Photographs and screenshots of photos usually shrink dramatically — often to a fraction of the original. Flat graphics, line art, and UI screenshots with large blocks of a single colour are exactly what PNG compresses well, so those files can come out barely smaller or even larger as JPG.
JPG compression discards image data permanently. Converting back to PNG later restores the file extension but not the detail, so keep the original PNG if the image still has editing ahead of it.
No. JPG cannot store transparency, so transparent pixels are flattened onto a solid background. If the transparency matters, stay with PNG or convert to WebP, which keeps an alpha channel and is still much smaller than PNG.
That happens with flat-colour images — icons, charts, screenshots of interfaces. PNG stores large uniform areas very efficiently, while JPG spends data trying to reproduce the hard edges between them. If the file grew, the original PNG was already the better format for that image.
Around 80 to 90 is a good default for photos: the difference is hard to see and the file is a lot smaller. Go lower only when you have a hard size limit, and check the result — text and sharp edges are where JPG artefacts show up first.
No. The conversion runs entirely in your browser, so the files never leave your device and there is no upload to wait for.
