What changes when you convert PNG to JPG
- JPG has no transparency, so any transparent parts of the PNG are filled with white rather than turning black.
- JPG is lossy. The Quality slider starts at 90%, which looks the same as the original for nearly every photo; lower it for a smaller file and the preview shows the new size before you download.
About PNG and JPG
- PNG is a lossless format: it keeps every pixel exactly and supports full transparency. That makes it ideal for screenshots, logos and graphics, but photos saved as PNG are often several times bigger than the same photo as a JPG.
- JPG (also written JPEG) is the most widely supported photo format. Its lossy compression keeps photos small, but it has no transparency and loses a little detail every time it's re-saved.
Tips for Mac
- macOS has a built-in option too: select images in Finder, right-click › Quick Actions › Convert Image (macOS 12 or later) converts to JPEG, PNG or HEIF. It can't make WebP, and it has no quality preview.
- Works on Apple silicon and Intel Macs alike – nothing to download from the App Store.

Frequently asked questions
Will I lose quality converting PNG to JPG?
At the default 90% quality the difference is practically invisible. JPG is lossy, so very low quality settings will show blur or blocky edges.
Can I convert several PNG files at once?
Yes. Add as many as you like; each converts on its own, and Download all saves them in one ZIP.
Are my photos uploaded to a server?
No. The conversion runs in your browser using your device's own processor, so your photos never leave your device. You can even disconnect from the internet once the page has loaded.
Where does the converted file go on my Mac?
Click Download. The file is saved to your Downloads folder (Finder › Downloads, or the dock).
