To convert JPG to PNG, drop your .jpg or .jpeg files into the box above and select Convert all. Each image is redrawn and saved as a lossless PNG in your browser, so nothing is uploaded. Each card shows the new size. Download the PNGs one by one or select Download all (ZIP) to get them in one file.
How to convert JPG to PNG
- Add your JPGs. Drag JPG or JPEG files onto the drop area, or select Select images. Up to 500 files or 2 GB at a time.

- Convert. Select Convert all. Each card shows the Original and Converted size and dimensions.
- Download. Select Download on a card, or Download all (ZIP) for every PNG. Use Reconvert after changing the size settings.
Why convert JPG to PNG?
JPG loses a little detail every time it's saved. PNG is lossless, so once a photo is a PNG you can open, edit and save it as often as you like without adding new compression damage. That makes PNG the safer working format for retouching, collages, memes with text, and design files.
Some upload forms, print templates and design tools also ask specifically for PNG files. Converting gives you a file they accept, with the exact same pixels as the JPG you started with.
JPG to PNG with a transparent background: is it possible?
Not by converting alone. JPG has no transparency channel, so every pixel in a JPG is solid. When you convert the file, those solid pixels are copied as they are, and a white background in the JPG is still a white background in the PNG.
To get a transparent PNG, the background has to be removed, either with a background removal tool or by erasing it in an image editor and saving as PNG. If you only need a round profile picture with transparent corners, the crop image tool can cut a circle and save it as PNG.
JPG vs PNG: which format should you use?
| JPG | PNG | |
|---|---|---|
| Compression | Lossy | Lossless |
| File size for photos | Small | Several times larger |
| Transparency | No | Yes |
| Sharp text and lines | Can blur or show halos | Stays crisp |
| Best for | Photos to share or upload | Editing, graphics, screenshots, logos |
Converting doesn't undo JPG compression. Any blockiness already in the JPG stays in the PNG. Converting simply stops it from getting worse.
Why is the PNG bigger than the JPG?
A JPG photo can be several times smaller than the same photo as a PNG, because PNG keeps every pixel exactly instead of discarding detail. That's expected. If the PNG is too big for where it's going, set a Max width before converting, or shrink the result with the PNG compressor. If you don't need PNG at all, keep the JPG and make it smaller with the JPG compressor.
How to convert JPG to PNG on Windows and Mac
On Windows, open the JPG in Paint, choose File › Save as and pick PNG. On a Mac, open it in Preview, choose File › Export and set Format to PNG. Both handle one image at a time. The converter on this page handles a whole batch and works on phones too.
Frequently asked questions
How do I convert JPG to PNG for free?
Drop the JPG into the converter on this page and select Convert all. It's free, with no sign-up, no watermark and no upload.
Does converting JPG to PNG improve quality?
No. The PNG has the same pixels as the JPG. It just won't lose any more quality when you edit and re-save it.
Will the PNG have a transparent background?
No. JPG files have no transparency, so the PNG keeps the same solid background. You need to remove the background separately to make it transparent.
Can I convert JPEG files as well as JPG?
Yes. JPG and JPEG are the same format, and the converter accepts both extensions.
How many JPGs can I convert to PNG at once?
Up to 500 files or 2 GB in a single batch, downloaded together as one ZIP file.
Are my photos uploaded to a server?
No. The conversion runs in your browser and the files stay on your device.
