About PNG to JPG Converter
PNG screenshots and graphics can be large, and some forms accept only JPG. This converter turns PNG files into JPG at the quality you choose, usually making them several times smaller while looking the same.
Transparent parts of a PNG are filled with a background colour you pick, white by default. Convert one file or many at once, compare the sizes in the list and download each JPG or a ZIP. Everything runs in your browser, so your images stay on your device. It is ideal for screenshots, scanned forms and graphics that a portal or email will not accept as PNG.
How to use PNG to JPG Converter
- Drop one or more PNG images, or try the sample.
- Set the quality and a background colour for transparent areas.
- Download each JPG or all of them as a ZIP.
Frequently asked questions
What happens to transparent parts?
JPG cannot store transparency, so transparent pixels are filled with the background colour you choose (white by default).
Why is the JPG much smaller?
JPG uses lossy compression that suits photos. At 85–92% quality the difference is hard to see, while the file is often 3–10 times smaller than the PNG.
How do I convert PNG to JPG without a black background?
Transparent pixels are filled with the background colour setting, which is white by default, so you never get an unexpected black background.
Which quality should I choose?
85–92% looks the same as the original for most images. Lower it if you need a smaller file.
