Why convert a JPG to PNG?
JPG and PNG are both everyday image formats, but they work differently. JPG simplifies the image a little each time it is saved, which keeps photos light. PNG is lossless: once your image is a PNG, saving it again will never degrade it.
Converting to PNG is useful when:
- you are going to edit the image several times, for example add text or annotations, and do not want it to lose a bit of quality with each save;
- a website, a template or a print service asks specifically for PNG files;
- you want to use the image in software that handles PNG better, such as some design or slide tools;
- you plan to remove the background later in another program, which requires a format that supports transparency.
What converting to PNG does and does not do
It is worth being clear about this:
- It does not improve quality. The detail that JPG compression removed is gone. The PNG looks exactly like the JPG, no sharper.
- It does not add transparency. A JPG has no transparent areas, so the PNG will have the same white or coloured background. You can remove the background afterwards in an editing tool.
- It usually makes the file bigger. Storing a photo without loss takes more space. A 1 MB JPG photo can become a 3 to 6 MB PNG.
Plume runs a lossless optimisation on the PNG (OxiPNG), so the file is as compact as it can be without changing a single pixel. Still, for photos you only want to share, JPG remains the lighter choice.
JPG or PNG: a quick comparison
JPG
Best for photos. Light files, opens everywhere, no transparency, loses a little detail each time it is saved.
PNG
Best for screenshots, logos, text and graphics. Lossless, supports transparency, but heavy for photos.
If you want something light that also supports transparency, WebP is a good middle ground: try JPG to WebP. And if you have a PNG that should really be a JPG, use PNG to JPG.
How to convert JPG to PNG in a few seconds
No software to install. Open this page on a computer, tablet or phone, then:
- drop your JPG files into the box, or tap to choose them;
- wait a moment while Plume converts and optimises each image;
- download the PNGs individually or all at once in a ZIP.
You can also resize during conversion by setting a maximum width or height. Smaller dimensions keep the PNG size under control, which helps if you need to upload it somewhere afterwards. For other formats, see the full image converter.
Safe conversion on your own device
Unlike most online tools that upload your files, Plume converts JPG to PNG inside your browser. Your images never leave your device, and the tool keeps working offline once loaded. EXIF metadata, including GPS location, is removed by default, and the orientation is kept correct.
It is free, with no account, no watermark and no daily limit on the number of files.
Common situations where PNG is required
Some services and tools ask for PNG specifically. A few examples:
- Design and print templates, such as mugs, T-shirts or stickers, where the printer prefers a lossless file.
- App stores and some online platforms that ask for icons or screenshots in PNG.
- Documentation and tutorials, where images will be annotated several times and must stay crisp.
- Background removal: converting first to PNG gives you a file that can hold transparency once the background is erased in an editor.
Outside these cases, a JPG is usually the lighter and more practical choice. If you only need a smaller file, Compress JPEG is the better tool.
