Is your PNG too big to upload, or does a website only accept JPG and refuse the picture you have?
Don’t worry, you are not alone. Add your PNG files below and press Convert. This PNG to JPG converter works in your browser, so nothing is uploaded, and it will not give your see-through logo a black box.
Your pictures never leave this computer. They are converted in your browser. Nothing is uploaded.
Pictures are converted at their own size. Nothing is resized or cropped unless it is an SVG, which you can draw at any width.
First, is JPG the right choice for your picture?
PNG and JPG are good at opposite things, so it is worth ten seconds before converting.
- A photograph saved as PNG: converting to JPG is exactly right. The file gets far smaller and nobody will see a difference.
- A screenshot, a chart, text or a logo: JPG leaves faint smudges around sharp edges and letters. It will still be smaller, but it will look a little worse, especially when zoomed in.
Here is a real example. I took a 768 pixel screenshot saved as PNG (105 KB). As a JPG at quality 90 it was 62 KB. As a WEBP at the same quality it was 36 KB, smaller still. So if the place you are uploading to accepts WEBP, choose WEBP in the Convert to box for screenshots.
Why some converters give you a black background
PNG files are often see-through in places, like a logo with no background or an icon with round corners. A JPG has no way to store see-through, so those parts have to be filled with something.
The obvious way of saving a JPG in a browser fills them with black. I checked it in Chrome: the see-through half of a test picture came back pure black. That is where the black boxes behind logos come from.
This converter lays every picture on white first, and you can choose another colour in the Background box. Think of it like putting a cut-out paper shape on a sheet of card before photocopying it: you get to choose the colour of the card, rather than the copier choosing black for you.
Choosing the quality
The slider starts at 90, which keeps photos looking the same as the PNG. If you need the file under an upload limit, try 80, then 70. Below 60 the picture can start to look blocky.
Note: if a form asks for a file under a certain size, like 100 KB, the image resizer can aim straight at a file size instead of making you guess with the slider.
Where this stops, honestly
- A JPG can never be see-through. If you need transparency kept, stay with PNG or use WEBP.
- Every save as JPG loses a little. Keep your original PNG if you might edit the picture again.
- Hidden details are not copied. The JPG is drawn from the pixels, so things like a camera model or location are left behind.
- Very large PNGs use a lot of memory on a phone, because the work happens on your own device.
Frequently asked questions
Does PNG to JPG reduce quality?
A little, always. At quality 90 you will not see it on a photograph. On text and sharp lines you may, if you zoom in.
Can I convert many PNG files at once?
Yes. Add them all and download the results one by one, or together as a ZIP. Files with the same name get a number added instead of replacing each other.
Is my picture uploaded anywhere?
No. It is converted by your browser. Load the page, turn the wifi off, and it still works.
