About JPG to PNG
PNG files are a lossless format, handy when a program or site asks for PNG. Turning a JPG into a PNG cannot bring back detail the JPG already lost, and the file will be larger. Drop the photos in, then save them one by one or all together as a zip.
How to use it in 4 steps
- 1Drop your JPG photos onto the box, or press Choose photos.
- 2Each is converted and shows a preview with its new size.
- 3Press Save, or Save all as one zip.
- 4Use the PNGs wherever a program or site asks for PNG.
What converting a JPG to PNG does and does not do
Saving a JPG as a PNG changes the file type but cannot bring back detail that JPG compression already removed. What it does give you is a lossless file: from now on, editing and re-saving as PNG will not degrade the picture further. It is useful when a program or form requires PNG, or when you want to edit a picture without adding more compression each time.
Expect a much bigger file. A photograph that is a few hundred kilobytes as JPG can be several megabytes as PNG.
A quick tip for graphics
If you want to make the background of a picture see-through, converting to PNG is only the first step: PNG can hold transparency, but a JPG has no transparent parts to begin with, so you need an editing tool or the Remove background page to create them.
Private by design
The picture is converted inside your own browser and is never uploaded. Your original JPG is not changed.
A quick example: a logo that keeps getting fuzzier
A friend sends your club’s logo as a JPG and you need to add text to it in an editing program several times over. Each time you save a JPG it is compressed again, and the edges around the letters slowly turn fuzzy. Convert the JPG to PNG first, do all your editing on the PNG, and the picture stays exactly as it was when you started.
A 400 KB JPG of a logo may become a PNG of 1 to 2 MB. The PNG is not sharper than the JPG was, it just stops further damage.
Good to know
Look closely at the PNG before you rely on it. Faint blocky patches around edges, called artefacts, are part of the JPG and will be carried into the PNG as they are. If the original picture came from a design file, ask for that or for a PNG, because it will be cleaner than any conversion. Use Remove background if you need see-through areas, and Compress photo if the finished picture has to be small again.
If you are only converting because a website insisted on PNG, there is nothing more to do: drop the file in, save it and upload it. The conversion does not alter the pixel size, so a picture that was 1200 pixels wide stays 1200 pixels wide.

Questions people ask
Why would I turn a JPG into a PNG?
Some programs and forms ask for PNG. It is also useful if you plan to edit the picture a lot, because PNG does not lose any more detail each time it is saved.
Will the picture look better?
No. Turning a JPG into a PNG cannot bring back detail that the JPG already lost. It just stores the same picture in a different kind of file.
Why is the PNG so much bigger?
JPG shrinks photos by discarding fine detail. PNG keeps everything, so the file for a photo is many times larger. Photos may go from around 1 MB to many megabytes.
Can I get a see-through background this way?
No. A JPG has no see-through areas, so the PNG will not either. To cut out the background, use Remove background.
Is my photo uploaded?
No. It stays on your device.
