JPG to PNG Converter

What it does

Converting a JPG to PNG does not bring back detail the JPG already lost: the PNG is an exact copy of the JPG as it is now, usually several times larger. What it gives you is a file that can be edited and saved again and again without getting worse, which every new JPG save does a little. It is the right step before editing a picture, or when a tool asks specifically for PNG.

How to use it

1. Choose the images from your device. They are read in the browser and go no further.
2. Pick the format to convert to and, for JPG and WebP, the quality.
3. Convert, then download each image or all of them together in a ZIP file.

Frequently asked questions

Why is the PNG so much bigger than the JPG?
Because PNG keeps every pixel exactly, while JPG throws away detail the eye barely sees to save space. A photo saved as PNG can be five to ten times larger. For photos you only want to share, staying with JPG is usually better.

Can I convert several images at once?
Yes. Choose as many as you like; each one is converted in turn and listed with its size before and after. Download them one by one or all together in a ZIP file.

Will my phone photos come out the right way up?
Yes. Phones often save photos lying on their side with a note saying which way is up. The converter applies that note, so the new file is upright in any program, even those that ignore it.

Can I convert HEIC photos from an iPhone?
Yes, in any browser. Safari opens HEIC by itself; in Chrome, Firefox and Edge the converter first loads a HEIC decoder, about 1.5 MB, the first time you choose a HEIC photo. The photo is still read only in your browser.

Are my images uploaded anywhere?
No. They are read by your browser and the PDF is built in the page itself. There is no upload and nothing is stored, and once the page has loaded it keeps working with the network switched off.
