MarukitPNG to JPG Converter
Marukit's PNG to JPG converter is a free web tool that turns PNG images into JPG files, up to 20 at once. You choose what transparent areas become and how much JPG compression to use.
Your images are processed inside your browser and are never uploaded to our servers.
About this tool
PNG is lossless, so a photo saved as PNG is often several times bigger than it needs to be. As a JPG it usually gets much smaller, and every upload form and app accepts it. JPG has no transparency, so transparent pixels are filled with white, or with black for light logos and text.
How to use the PNG to JPG converter
- Choose one or more PNG images (other formats work too).
- Keep JPG selected and choose what transparent areas become: white or black.
- Set the quality: 92 looks like the original, 80-85 gives smaller photos.
- Press Convert and download each JPG, or all of them as a ZIP.
PNG or JPG: which one should you keep?
- Photos: JPG. It is much smaller and opens everywhere.
- Screenshots, charts and images with text: PNG keeps letters and edges sharp. Convert only if a form needs JPG.
- Logos and icons with a transparent background: keep PNG, or use WebP. JPG fills the transparency.
- A form wants a JPG under a size limit? Convert here, then use Compress Image to 100KB if it's still too big.
Not working? Quick fixes
- A white logo disappeared: its transparent background became white. Choose Black under 'Transparent areas become'.
- The JPG is bigger than the PNG: this happens with simple graphics. Keep the PNG, or lower the quality.
- 'This image couldn't be processed': the file may be damaged or too large for this browser.

Frequently asked questions
Will converting PNG to JPG make the file smaller?
For photos, usually by a lot. For screenshots, logos and drawings with flat colours, a JPG can be about the same size or even larger, and edges look less crisp. The size of every result is shown, so you can keep the PNG if it's smaller.
What happens to the transparent background?
JPG can't store transparency, so transparent areas are filled with the colour you choose: white by default, or black for white logos and text.
Which JPG quality should I use?
92 (the default) looks the same as the original for almost every image. 80-85 gives smaller files for photos you share online. Use 95-100 for screenshots with small text.
Can I convert several PNG files at once?
Yes, up to 20 at a time. Download them one by one or together as a ZIP.
Is my image uploaded?
No. The conversion runs in your browser, so your images never leave your device.
