PNG to JPG converter
Turn a PNG into a JPG, choose the colour that replaces the transparent background, and get a file that is often several times smaller — free, in your browser.

How to convert PNG to JPG
- Drop your PNG into the box above.
- Look at the preview. If the PNG had a transparent background, set the background fill colour to what you want behind it — white for most documents, black for dark product shots.
- Choose a JPG quality. 90 is indistinguishable from the original for photos; 75 halves the file again; below 60 you start to see blocking in smooth areas.
- Download. Nothing is uploaded, and your original PNG is untouched.
What actually happens to the transparency
PNG stores an alpha channel: every pixel carries an extra number describing how see-through it is. JPEG has no such thing — it records only red, green and blue. So when you convert, the transparent pixels have to be composited onto something, and that something is a solid colour you choose.
This is why converting a logo with soft, semi-transparent edges to JPG produces a visible fringe: the tool blends the logo against your chosen colour, and the anti-aliased edge pixels become a fixed blend rather than transparency. If you need the transparency to survive, export to PNG or WebP instead.
Why the JPG is usually much smaller
PNG is lossless — it records every pixel exactly, which is why a screenshot of a busy page can reach several megabytes. JPG is lossy: it transforms the image, throws away detail the human eye is poor at noticing, and stores the rest efficiently. For photographic content that typically means a five- to ten-fold reduction at a quality setting nobody can distinguish on screen.
Flat colour graphics behave differently. A simple diagram or logo with large areas of one colour can actually be larger as a JPG, because the format adds noise around sharp edges rather than compressing them away. Check the size readout after converting — it is right there next to the preview.
When not to convert PNG to JPG
- Logos and icons — sharp edges and flat colour are exactly what JPG is bad at. WebP or PNG keeps them clean.
- Screenshots of text — letters get fuzzy outlines with visible ringing. Keep PNG, or use WebP lossless.
- Anything you will edit again — every lossy save takes another step down. Keep the PNG master.
- Images that must match the original exactly — for example artwork going to a print service that verifies pixel values.
Frequently asked questions
Is PNG to JPG conversion free here?
Yes, with no sign-up and no watermark. There is no upload step, so it is also fast regardless of file size.
Will the image be blurry after converting?
At quality 90, no. Text and thin lines can soften slightly even at high quality, which is why screenshots of text are better kept as PNG.
How do I keep the transparent background?
You cannot keep it in a JPG — the format does not support transparency. Use the converter and choose PNG or WebP as the output format instead.
Can I convert several PNG files at once?
Yes. The batch converter handles multiple files and gives you a download link for each one; the batch compressor does the same with resizing and compression.
What is the difference between JPG and JPEG?
Nothing — they are the same format with two spellings. The file extension you get here is .jpg.
