How do I convert PNG to JPG for free?
Upload the PNG above, set the quality you want, and download the JPG. It is free and runs locally in your browser.
Does PNG to JPG make the file smaller?
Usually yes, especially for photos, because JPG uses lossy compression while PNG is lossless. The quality slider lets you balance size against detail.
What happens to transparency?
JPG cannot store transparency, so transparent areas are filled with a solid background. Keep the PNG if you need transparent edges.
Is the PNG uploaded to a server?
No. The conversion happens in your browser and the file stays on your device.
Why is my PNG so much bigger than a JPG of the same photo?
Because PNG is lossless: it stores every pixel exactly, which is expensive for a photograph with millions of subtly different colours. JPG throws away detail the eye does not miss, and for photos that is an enormous saving.
What quality setting should I use for a JPG?
80 to 85 for a photograph. The slider defaults to 92, which is higher than most people need, and below about 70 the artefacts start to show on smooth areas like skies and skin.
Should I ever convert a screenshot from PNG to JPG?
Almost never. JPG is built for photographs, and it smears sharp edges and text into visible fringing. A screenshot, a logo, or line art should stay a PNG, or become a WebP if size matters.
What happens to the transparent background?
It gets filled in, because JPG cannot store transparency. Check the result before publishing: a logo that looked correct against white will show a visible box on any other colour.
Does converting PNG to JPG lose quality?
Yes, by design. JPG is lossy and discards detail to get small. For a photo that is a good trade; for text and sharp edges it is not.
