JPG to PNG Converter

Drop a JPG, get a PNG. Nothing is uploaded.

Resize

The shape is always kept, so the other side follows. Neither maximum ever ENLARGES a picture that is already smaller than it.

Pixels for either maximum, and a percentage for the last one. It is ignored while Resize is keeping the original size.

Nothing is uploaded. Your file is read in your browser and never leaves your computer.

What this does

Every camera and every phone writes JPG. A PNG keeps every pixel exactly and keeps its transparent parts transparent, which is what a logo, a label or a screenshot needs. It is what a photograph of a print arrives as, and what a listing wants back.

How it works

  1. Choose your JPG fileDrag a JPG file onto the box above, or press it and pick one. It is read in your browser, so nothing is uploaded.
  2. Wait for the PNGThe conversion runs on your own computer, so how long it takes depends on your machine and the size of the file, not on a queue.
  3. Download the PNGPress the download button. The PNG file lands in your downloads folder, ready for your slicer.

About the formats

Why your file is a JPG
JPEG. Every camera and every phone writes JPG.
Why you want a PNG
Portable Network Graphics. A PNG keeps every pixel exactly and keeps its transparent parts transparent, which is what a logo, a label or a screenshot needs.
What a PNG holds
Exact pixels with no quality loss, and real transparency.
What changes on the way to PNG
A JPG has already thrown detail away and a PNG keeps exactly what is left, so the file usually grows without looking any better.
Where this format turns up
It is what a photograph of a print arrives as, and what a listing wants back.

Questions

Is JPG to PNG Converter free?

Yes. Every tool on Short Work Tools is free, with no account, no sign-in and no limit on how many files you run through it. It runs on your own computer, so it costs us nothing to give away.

Is my file uploaded anywhere?

No. Nothing is uploaded. Your file is read in your browser and never leaves your computer. There is no upload step, no server copy and nothing kept afterwards, which is also why it works with the network switched off once the page has loaded.

What does the PNG keep from the JPG?

Exact pixels with no quality loss, and real transparency. A JPG has already thrown detail away and a PNG keeps exactly what is left, so the file usually grows without looking any better.

How large a file can I use?

Up to 250 MB. The limit is your browser's memory rather than an upload size, because the file never goes anywhere; a file larger than that is refused with a message rather than crashing the tab.

Which programs write JPG files?

Every camera and every phone writes JPG. It is what a photograph of a print arrives as, and what a listing wants back.

Does the converted picture keep the information the camera wrote into it?

No, and there is no setting for it because there is nothing to set. The picture is decoded to pixels and drawn onto a fresh canvas, and a canvas has no place to put the camera model, the date or the GPS position the original carried, so none of it is in the file you get back.
