Do you need a PNG, and all you have is a JPG from a phone, a camera or a website?
Don’t worry, you are not alone, and it takes about ten seconds. Add your pictures below and press Convert. This JPG to PNG converter runs in your browser, so nothing is uploaded, and it takes .jpeg and .jfif files as well, which is what Windows often saves when you copy a picture out of a browser.
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.
What converting to PNG actually does, and what it does not
This is the part worth reading before you convert a folder of holiday photos.
A JPG throws detail away to make the file small, and it does that once, when the picture is saved. A PNG keeps every pixel exactly as it is given. Converting a JPG to a PNG keeps what is left, faithfully. It cannot put back what the JPG already threw away.
Think of it like photocopying a photocopy onto better paper. The paper is better. The copy is still a copy.
So converting is the right move when something needs a PNG, and it is not a way to improve a picture. Two honest consequences follow from that, and both surprise people.
The file usually gets bigger
A photo saved as PNG is often several times the size of the JPG, because PNG does not throw anything away. That is normal and it is not a fault in the converter.
If you were converting in order to make the file smaller, PNG is the wrong direction. Our image resizer makes the picture smaller in pixels, which is what actually shrinks a photo.
It does not add see-through parts
PNG can hold see-through areas. A JPG never has any, so a converted JPG has none either. The white background in your photo stays white, it does not become see-through.
Removing a background is a different job, and anything promising to do it while converting is either guessing or sending your picture to a server.
When you genuinely need a PNG
These are the reasons that come up over and over, and in all of them the conversion is the right answer.
- A site or a form only accepts PNG. Plenty of upload forms and printing services do.
- Screenshots and text. JPG smears the edges of letters. If you are going to crop, mark up and save the picture again, working in PNG stops the smearing getting worse each time.
- A logo or a diagram with flat colours. PNG keeps flat areas clean, and it is usually smaller than JPG for that kind of picture.
- Software that refuses JFIF. Windows saves .jfif from some browsers, and older programs simply will not open it, even though it is an ordinary JPEG inside.
- You are going to edit it repeatedly. Every JPG save loses a little more. PNG saves lose nothing.
JFIF, JPEG and JPG are the same thing
This confuses a lot of people, so here it is plainly.
JPG and JPEG are the same format with two spellings, left over from the days when Windows allowed only three letters after the dot. JFIF is the full name of the container that nearly every JPEG uses, and Windows started saving that name when copying pictures out of a browser.
All three go into the converter above and come out as PNG. If a program refuses your .jfif, renaming it to .jpg usually works too, and this page tells you so rather than pretending you need a tool for that.
Several pictures at once
Add as many as you like. Each one is converted and offered on its own line, and there is a ZIP of all of them at the bottom when there is more than one.
Two files with the same name do not overwrite each other. The second becomes name-2.png, so nothing goes missing quietly.
Nothing is uploaded, and here is the honest limit
Your pictures are converted inside your own browser. They do not travel to a server, there is no queue, and no copy of your file sits on somebody’s disk waiting to be deleted.
The limit of that: everything uses your own computer’s memory, so a hundred photos from a modern phone will be slow on an old machine. Do them in batches if the tab starts to struggle.
Frequently asked questions
Does converting JPG to PNG improve the quality?
No. It preserves exactly what the JPG already has. Nothing that was thrown away when the JPG was made can come back.
Why is my PNG bigger than the JPG?
Because PNG keeps every pixel rather than throwing detail away. For photographs that always means a larger file. For screenshots and flat graphics it is often smaller.
Can I make the background see-through while converting?
Not here, and not honestly anywhere in one click. The JPG has no see-through information in it, so removing a background means guessing which pixels to cut, which is a separate job with a separate tool.
Is it safe? Where do my pictures go?
They stay on your computer. The conversion happens in the page you are reading, so the file never leaves the device. You can even turn your internet off after the page has loaded and it still works.
What about the other direction, PNG to JPG?
That is on our PNG to JPG converter, which also lets you choose what happens to see-through areas so a logo does not come out with a black box behind it.
