Why convert PNG to JPG?
PNG is a lossless format designed for graphics, logos and screenshots. It's great with flat colors and text, but when it contains photos the files get huge: a phone screenshot or a photo saved as PNG can weigh 5, 10 or even 20 MB.
JPG is built precisely for photographs. Converting PNG to JPG usually makes the same content 70–90% smaller with no visible difference. It's the easiest way to email images, upload them to sites with size limits or simply save space.
How to convert PNG to JPG, step by step
- Drag your PNGs onto the area above, paste them with Ctrl+V or tap “Choose files”.
- Adjust the quality. At 90% you won't notice a difference; at 75% the file will be even lighter.
- Pick the background color. JPG has no transparency, so transparent areas are filled with white, black or any color you like.
- Download the JPGs one by one or as a ZIP.
If you change the quality or background after converting, hit “Apply settings” and they're regenerated without uploading anything again.
PNG or JPG: a quick guide
| Use PNG for… | Use JPG for… |
|---|---|
| Logos and icons | Photographs |
| Images with transparency | Images you'll email |
| Screenshots full of text | Photos for websites and social media |
| Images you'll keep editing | Files that must stay small |
If your PNG is a logo with transparency, think twice before converting it to JPG — you'll lose the transparent background. For the web, a modern alternative that keeps transparency and stays small is converting to WebP.

Which quality should you choose?
For photos and screenshots you're going to share, 85–90% is the sweet spot: the file shrinks dramatically and you can't see the difference. If the image has small text or fine lines (a spreadsheet screenshot, say), go up to 92–95% so letters don't show halos. If it has to be as small as possible for a form, drop to 70% and check the preview — you can change the value and press “Apply settings” as often as you like without re-uploading anything.
Frequently asked questions
How much smaller is a JPG than a PNG?
For photos and screenshots, a JPG is usually 70–90% smaller. For graphics with few colors the difference is smaller.
What happens to the PNG's transparent background?
JPG doesn't support transparency, so the background is filled with the color you choose. White is the default.
Do I lose quality going from PNG to JPG?
JPG is a lossy format, but at 85–90% quality the difference isn't visible in photos. With tiny text or very sharp graphics you may notice a little softening at the edges.
Can I convert phone screenshots?
Yes, it's one of the most common uses: PNG screenshots are heavy and much easier to share as JPG.
Is it safe?
Yes. Your images are never uploaded to a server; everything is processed on your device.
Does it work offline?
Once the page has loaded, the conversion doesn't need the internet because it runs in your browser.
