What Happens to Transparency?
JPG has no alpha channel, so transparent areas of a PNG are filled with white during conversion. If you need to keep a transparent background (for a logo, icon or sticker), convert to WebP instead or keep the PNG.
For screenshots with sharp text, PNG often stays crisper. JPG is the better choice for photos, where it typically cuts file size by 50–90%.
Frequently Asked Questions
Will converting PNG to JPG reduce quality?
JPG uses lossy compression, so a small amount of detail is discarded. At 85–95% quality the difference is usually invisible for photos. Text and sharp edges show artifacts sooner, so use a higher quality setting for screenshots.
Why is my JPG background white instead of transparent?
The JPG format does not support transparency. Transparent pixels are filled with white. Use PNG or WebP if you need to keep the transparent background.
Can I convert multiple PNG files at once?
Yes. Select or drop as many PNG files as you need. Each one is converted in your browser and you can download them all together as a ZIP archive.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser using JavaScript. Your files never leave your device, which is why it also works with private photos and confidential documents.
What quality setting should I use?
For photos, 80–90% gives a much smaller file with no visible loss. For images that will be printed or edited further, use 95–100%. Below 60% compression artifacts become noticeable.
