About This Tool
Why use PNG to JPG?
Convert PNG images to JPG at quality 92 — high enough that the difference is invisible in normal viewing, while the file is typically a fraction of the PNG's size. Transparent areas are filled with white before encoding, because JPEG has no alpha channel at all.
That white fill is the detail that catches people out elsewhere. A transparent PNG sent straight to a JPEG encoder comes out with a black background, because an empty canvas is transparent black. Filling white first is what makes a logo or a screenshot with rounded corners still look right. If you need the transparency itself, JPG is the wrong destination — stay on PNG or move to WebP.
Key Benefits
Transparency handled properly
Transparent pixels are filled with white before encoding, so you get a clean background instead of the black one a naive converter produces.
Quality 92
High enough that compression is not visible in normal viewing, while cutting file size dramatically against a lossless PNG.
Much smaller files
Photographs saved as PNG are often several times larger than they need to be; JPEG is what the web and email were built for.

PNG to JPG FAQs
What happens to transparent areas?
They become white. JPEG has no alpha channel, so transparency has to be flattened to something — this tool fills white before encoding, which is what a logo or screenshot normally needs.
How much smaller will the file be?
It depends entirely on the image. Photographs usually drop by 70 to 90 per cent. Flat graphics, screenshots and line art sometimes barely shrink, and can even grow — those belong in PNG.
Is the conversion reversible?
No. JPEG discards detail permanently. Keep the original PNG if you might need to edit the image again later.
When should I keep PNG instead?
Whenever the image has transparency, sharp text, screenshots or flat blocks of colour. JPEG blurs hard edges, and PNG is usually smaller for that kind of image anyway.
