How to use this tool
- Add your PNG files. Drag them into the box or tap Choose PNG. You can add many at once.
- Set the quality if you like. The default of 92% looks identical to the original for most images. Lower it for an even smaller file.
- Convert and download. Click Convert to JPG, then save each image or download them all as a ZIP.
Why convert PNG to JPG?
PNG keeps every pixel exactly as it was, which is great for logos but makes photos and detailed screenshots very large. JPG was designed for photos: it removes detail your eye is unlikely to notice, so the same picture often takes up far less space.
Converting makes sense when a PNG is too big to email, a website rejects it because of its size, or a form only accepts JPG. It's also a simple way to free up storage if you have folders of phone or computer screenshots.
When to keep the PNG instead
- It has a transparent background. JPG can't store transparency, so a logo on a transparent background gets a solid white background.
- It's mostly flat color or small text. Logos, charts and diagrams can look slightly blurry around the edges as JPG, and may not even get smaller.
- You'll keep editing it. Keep the PNG as your master copy and export a JPG when you're done, since each JPG save loses a little detail.
What quality setting should I use?
| Quality | Best for |
|---|---|
| 90–100% | Printing, or images with fine detail |
| 75–90% | Everyday sharing, email and websites |
| 50–75% | Getting the file as small as possible, where some softness is acceptable |
Have a strict limit such as 100 KB? Use Compress Image to 100 KB instead, which finds the right quality for you. To go the other way, use JPG to PNG.
Frequently asked questions
Will converting PNG to JPG reduce quality?
Slightly, because JPG is a lossy format. At the default 92% setting the difference is very hard to see on photos. Sharp text and thin lines show it first.
What happens to a transparent background?
JPG does not support transparency, so transparent areas are filled with white. Keep the PNG if you need to preserve the transparency.
How much smaller will my file be?
It depends on the image. Photos and detailed screenshots usually shrink a lot, while simple graphics with few colors may shrink little or even grow, because PNG already handles those well.
Are my PNG files uploaded anywhere?
No. The conversion runs inside your browser, so your images stay on your device.
