About png to jpg
PNG to JPG converts a lossless PNG into a much smaller JPEG. It is the standard way to get a logo, icon or screenshot down to a size that can go into an email, an upload form or a document.
The catch is transparency. PNG can store transparent pixels and JPEG cannot, so every transparent area has to be filled with a solid colour before saving. Get it wrong and a logo that looked clean on a website arrives with black or white blocks behind it. The background control on this page makes that explicit rather than leaving it to chance: choose white for most professional uses, black for a dark interface, or a custom colour to match the page it will sit on.
Beyond that, quality behaves the way you would expect. Around 90 percent is visually indistinguishable from the original and still gives a large saving. Below roughly 70 you will notice ringing around text and hard edges, which is the main reason to stay high when converting graphics.
Frequently asked questions
What happens to the transparent parts?
They are filled with the background colour you select. White is right for most documents and websites, and you should pick something closer to your page colour if the image will sit on a non-white background.
Why did my logo come out with a black box behind it?
That is what a converter did when you did not choose a background colour. Transparent areas defaulted to black. Set the background to white on this page and reconvert.
How much smaller will it get?
For a typical logo or screenshot, between 60 and 90 percent smaller. For an image that is mostly photographic content, less, because JPEG is not much better than PNG on that kind of picture.
What quality should I choose?
90 percent for anything going into a document or email, where the file might be printed or scaled up. 70 to 80 percent is fine for a web page where the file will be viewed once at its natural size.
Will the text and edges stay sharp?
At 90 percent, yes. Below about 70 percent, thin text and hard edges pick up visible halos, so keep it higher for graphics.
Is there a way to keep both transparency and a small file?
Yes, convert to WebP instead. It supports transparency and is usually much smaller than PNG. The only downside is narrower compatibility with older software.
