Convert PNG to JPG
This is a size conversion, and it is usually the right one when the image is a photograph. PNG stores every pixel exactly, which is wonderful for a logo and wasteful for a picture of a beach: photographic content has no long runs of identical colour for lossless compression to exploit, so PNG photos routinely come out many times larger than they need to be. Email attachment limits, upload caps and slow pages are the symptoms.

Why convert PNG to JPG?
The two things to check before converting. First, transparency: if the PNG has a cut-out background, JPG will fill it with white and there is no undo, so WebP is the better target. Second, content: if the image is a screenshot, a diagram, a chart or anything with sharp text or flat colour blocks, JPEG compression will smear those edges and PNG is worth keeping.
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.
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.
Note that JPG does not support transparency, so any transparent areas in your PNG files will be filled with a solid background after conversion.
What this converter does to your PNG file
The PNG is decoded and re-encoded as JPEG by your browser at the quality you choose, defaulting to 0.9. The PNG was lossless, so this is the first lossy encode the image has been through, and the quality slider genuinely controls how much detail is given up rather than dividing up a loss that already happened. Because JPG has no alpha channel, any transparent area is composited onto solid white before encoding, including the soft anti-aliased edges around a cut-out, which are baked against that white.
PNG vs JPG at a glance
| PNG | JPG | |

| Compression | Lossless | Lossy |
| Transparency | Yes | No |
| Best for | Logos, screenshots and graphics with transparency | Photos and general web images |
What changes when you convert PNG to JPG
| What happens | |
|---|---|
| Image quality | Reduced, by however much you choose. JPG is lossy; the quality control above sets the trade. Keep the PNG original if you may need to edit it again. |
| Transparency | Lost. JPG cannot store an alpha channel, so transparent areas are filled with solid white. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the JPG 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. PNG files here are single images. |
| File size | Smaller, usually by a lot. The exact saving depends on the image and the quality setting. |

Frequently asked questions
Does converting PNG to JPG lose quality?
Yes, by design, and by however much you choose with the quality control. PNG is lossless and JPG is not, so this is the first real compression the image has been through. At high quality the difference is invisible on a photograph and obvious on text.
What happens to my transparent background?
It becomes white. JPG has no way to store transparency, so transparent pixels are composited onto a solid white background and soft edges are baked against it. Convert to WebP instead if the transparency matters.
Why is my PNG so large in the first place?
Because it is probably a photograph. PNG compresses runs of identical colour extremely well and photographic noise extremely badly, so it is the ideal format for a logo and a poor one for a snapshot.
Should I convert a screenshot from PNG to JPG?
Usually not. Screenshots are full of sharp text and flat colour, which is exactly what JPEG handles worst: the result looks fuzzy around letters. Keep the PNG, or use WebP if size is the problem.
What is a PNG file?
PNG is a lossless format with transparency support, ideal for graphics, logos and screenshots.
What is a JPG file?
JPG (JPEG) is the most common photo format, using lossy compression for small file sizes.
Is it free to convert PNG to JPG?
Yes. There are no limits, no watermarks and no account needed. Convert as many PNG files as you like.
Are my files private?
Completely. Your PNG files never leave your browser and are never uploaded to a server, so your images stay on your device.
