Convert JPG to PNG
There are two good reasons to do this and one bad one. The good reasons: you are about to edit the image and want no further compression loss with every save, or something downstream demands PNG specifically, which a surprising number of tools, printers and internal systems still do.
Drop your JPG files below and download PNG in seconds. Free, unlimited and completely private: the conversion runs inside your browser, so your files never leave your device and are never uploaded to a server.

Why convert JPG to PNG?
The bad reason is the belief that PNG will make the photograph look better. It will not. Converting a JPG to PNG freezes the picture exactly as the JPEG encoder left it, artefacts and all, in a file that is usually several times larger. If you want a better image, the only route is a better original.
JPG has been the default photo format since the nineties and opens everywhere, from ancient office software to modern phones. Its lossy compression shrinks photos dramatically while keeping them looking good at normal viewing sizes. It cannot store transparency, so transparent areas are filled with a solid background.
PNG stores every pixel exactly as it was saved, which makes it the safe choice whenever detail matters more than file size. It supports a full alpha channel, so logos and UI elements keep clean, soft edges on any background. The tradeoff is that photos saved as PNG can get large.
What this converter does to your JPG file
Your browser decodes the JPG and writes it out as PNG, which is lossless, so the result is a pixel-for-pixel copy of what the JPEG decoder produced, including every compression artefact already in the source. Nothing further is lost from that point on, which is the actual benefit. There is no transparency to recover, because JPG never had an alpha channel, so the PNG comes out fully opaque. There is no quality setting, because PNG does not have one, and EXIF is not carried across.
JPG vs PNG at a glance
| JPG | PNG | |
|---|---|---|
| Full name | JPEG image | Portable Network Graphics |
| Compression | Lossy | Lossless |
| Transparency | No | Yes |
| Best for | Photos and general web images | Logos, screenshots and graphics with transparency |
What changes when you convert JPG to PNG
| What happens | |
|---|---|
| Image quality | Unchanged from here on. PNG is lossless, so it preserves exactly the pixels decoded from the JPG file. It cannot restore what the JPG encoder already discarded. |
| Transparency | JPG has no alpha channel, so there is no transparency to lose. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the PNG file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not applicable. JPG files here are single images. |
| File size | Larger, often several times. Lossless formats cannot match what a lossy encoder already achieved. |

Frequently asked questions
Does converting JPG to PNG improve quality?
No, and this is the most common misunderstanding about image conversion. PNG preserves exactly what it is given. Detail the JPEG encoder discarded is gone, and no format can reconstruct it.
Why is the PNG so much bigger than the JPG?
Because it is lossless and the content is photographic. PNG has to record every pixel, including the noise and the JPEG artefacts, and none of that compresses well.
Will the PNG have a transparent background?
No. JPG has no alpha channel, so there is no transparency in the source to carry over. The PNG will be fully opaque. Removing a background is an editing job, not a conversion.
What is a JPG file?
JPG (JPEG) is the most common photo format, using lossy compression for small file sizes.
What is a PNG file?
PNG is a lossless format with transparency support, ideal for graphics, logos and screenshots.
Is it free to convert JPG to PNG?
Yes. There are no limits, no watermarks and no account needed. Convert as many JPG files as you like.
Are my files private?
Completely. Your JPG files never leave your browser and are never uploaded to a server, so your images stay on your device.
