How do I save a JPG as a PNG?
Drop the JPG here, choose PNG and download the result. The picture looks the same, but it is now stored without further compression loss, so you can edit and save it again without it degrading.
Convert JPG to PNG
Save JPG photos as lossless PNG files. Nothing is uploaded.
Your files never leave this device.
Convert JPG images to PNG by dropping them here and choosing PNG. PNG is lossless, so the new file keeps every pixel of the JPG without losing more quality, but it cannot bring back detail the JPG already discarded, and the file is usually larger. The conversion runs in your browser, with no upload and no limit.
How to use
- Drop your JPG or JPEG files onto the page.
- Choose PNG as the output format.
- Check the file size shown next to each result.
- Download each PNG, or all of them as a ZIP.
Frequently asked questions
Does converting JPG to PNG improve the image quality?
No. PNG only stops new quality loss; it cannot restore detail the JPG compression already removed. A blurry or blocky JPG stays blurry or blocky as a PNG.
Why is the PNG so much bigger than the JPG?
PNG stores every pixel without discarding anything, while JPG throws away detail to save space. Photos therefore grow a lot when saved as PNG, often to several times the original size.
Does JPG to PNG make the background transparent?
No. PNG can hold transparency, but converting does not remove anything from the picture, so a white or colored background stays exactly as it was. Removing a background needs an image editor.
Is there a quality setting for PNG?
No, because PNG is lossless. The quality slider appears only for formats that compress with loss, such as JPG, WebP and AVIF.
When is it useful to convert JPG to PNG?
It helps when you will edit and save the image many times, when a form or program accepts only PNG, or when you want to avoid adding another round of JPG compression. For simple sharing, the JPG is usually enough.
How can I make the PNG smaller afterwards?
Use the image compressor and choose PNG as the output; it can reduce the size while keeping the file a PNG. Or reduce the pixel dimensions first if the image is larger than you need.
What does converting JPG to PNG actually do?
A JPG is already compressed, and the detail it threw away is gone for good. Saving it as PNG writes the pixels you can see today into a lossless file. Nothing is gained in sharpness or color, but nothing is lost from this point on.
That distinction matters. If you expect a cleaner, sharper picture, a PNG will disappoint you. If you want a stable copy that you can open, edit and save again without extra damage, it is the right choice.
When is a PNG the better working copy?
Each time you save a JPG after editing, it is compressed again, and small errors pile up. If you plan to crop, annotate, adjust and save in several rounds, convert once to PNG, do all the edits, and make a final JPG only at the end with the PNG to JPG page.
Some programs and online forms also accept only PNG. Screenshots, interface mockups, diagrams and pictures with text are often requested as PNG because their sharp edges survive without artifacts.
What should you expect from the file size?
Expect it to grow. A photo that is a few hundred kilobytes as JPG can easily become several megabytes as PNG. That is normal, and it is the price of storing every pixel exactly.
If the PNG is too heavy for an upload or an email, open the image compressor and choose PNG output, or scale the picture down with the image resizer first. When the picture is a photo and file size is what you care about, the original JPG, or a modern format from the JPG to WebP page, is almost always the smaller option.
Where does the transparency come from?
It does not come from this conversion. PNG supports transparent areas, but a JPG has none to carry over, so the new file is fully opaque. To get a cutout, you need an editor that removes the background; once you have a transparent PNG, you can use it as a logo or overlay. Everything else about format pairs lives on the main image converter page.
