What converting JPG to PNG does, and what it cannot do

PNG is lossless: once your picture is a PNG it can be edited and saved again and again without losing anything more. That is the reason to convert, when you are going to edit a picture, add text or arrows to a screenshot, or a form asks for PNG.

What a conversion cannot do is bring back detail. A JPG already threw some away when it was first saved, and the PNG keeps exactly what is left, blur and blocky edges included. It also cannot make the background see-through: a JPG has no transparency, so the PNG has none either. To cut out a background, use the background remover.

Why the PNG is bigger

Expect the PNG to be two to ten times the size of the JPG for a photo. JPG is built for photographs and discards fine detail you barely see; PNG stores every pixel, and in a photo almost every pixel differs from its neighbour. For a screenshot or a logo the difference is much smaller, because flat colour compresses well in PNG.

If the file only has to be smaller, keep it as a JPG and compress it instead, or choose WebP above, which is far smaller than PNG and still opens in every browser.

How to convert JPG to PNG

  1. Choose one or more JPG files (a ZIP is offered when there are several).
  2. PNG is already chosen. Each picture is converted as soon as it is added.
  3. Download each PNG, or all of them at once as a ZIP.

The picture keeps its exact width and height, and a phone photo is turned the right way up as it is saved. Camera details, location and other metadata are not copied into the PNG.

Frequently asked questions

Is my picture uploaded?

No. The pictures are read and saved again by your own browser, inside this page, and are never sent to a server. You can turn off Wi-Fi once the page has loaded and it still works.

Will converting to PNG improve the quality?

No. The PNG is an exact copy of the JPG as it is now, so it looks the same. What changes is that further edits and saves no longer lose quality.

Can I make the background transparent?

Not by converting: a JPG has no transparent parts, so neither does the PNG made from it. Use the background remover, which saves a PNG with the background cut out.

How many pictures can I convert at once?

As many as you like. They are converted one after another, and with more than one a single ZIP download is offered. Very large photos take a moment each on a phone.

Does it work with .jpeg and .jfif files?

Yes. JPG, JPEG and JFIF are the same format with different endings.

Is the JPG to PNG free?

Yes. The JPG to PNG on The Daily Toolbox is free to use as often as you like, with no watermark and no file limit beyond what your device can handle.

Do I need to sign up or install anything?

No. It works in your web browser on a phone or computer, with no account and nothing to install. You can add the site to your home screen to open it like an app.
