About transparency
This is the one thing to know before converting: JPEG cannot store transparency. Where your PNG is see-through, the JPG will be white. That is usually what you want for a photo that happens to be saved as PNG, and it is a problem for a logo you intend to drop onto a coloured background.
If you need the background to disappear, keep the PNG — or convert to WebP instead, which compresses like JPEG but keeps the alpha channel intact.
When is JPG the better choice?
PNG stores every pixel exactly, which is wonderful for graphics and wasteful for photographs. A phone photo saved as PNG can easily be 10 MB where the same image as JPG is under 1 MB, with no difference you can see at normal viewing size. Email attachments, upload forms with size caps, and web pages that need to load quickly all favour JPG.
The rule of thumb: photographic content with soft gradients converts beautifully; flat colour, sharp text and anything needing transparency should stay as PNG.
Frequently asked questions
What happens to transparent areas?
They are filled with white. JPEG has no alpha channel, so transparency has to be flattened onto some colour and this tool uses white, which matches most pages and documents. If a transparent background matters to you, keep the PNG or place the logo on its final background in an editor first.
Are my PNG files uploaded anywhere?
No. The PNG is decoded and re-encoded to JPEG on your own device with a WebAssembly build of MozJPEG, Mozilla’s JPEG encoder. Your images never leave your browser.
How much smaller will the JPG be?
For photographs and screenshots of photographs, expect the JPG to be 60–90% smaller than the PNG. For flat graphics — logos, icons, charts, screenshots of text — the gain is much smaller and the JPG can even come out larger, because PNG is very good at exactly that kind of image.
What quality setting should I choose?
The default of 80 looks clean for almost any photo. Drop to 65–70 if you are chasing the smallest possible file for a web page, or push to 90–95 for images you will crop, print or edit later. Below about 60 you start to see blocky squares in smooth areas like sky and skin.
Will text and sharp edges still look good?
Less good than in the PNG. JPEG is built for photographs, so hard edges — screenshot text, thin lines, UI borders — pick up faint coloured fringes called ringing. If your PNG is mostly text or line art, stay with PNG, or convert to WebP, which handles both cases well.
Can I convert the JPG back to PNG later?
You can, but you will not get the original back. JPEG throws detail away permanently and transparency is already gone once it has been flattened. Keep the source PNG if you might need it again.
Is there a limit on file size or how many files?
No artificial limit. Because your own device does the encoding, the practical ceiling is browser memory — dropping dozens of screenshots or photos at once is fine on a typical laptop or phone.
