Free PNG to JPG Converter
Turn PNG images into compact JPGs in your browser, with a quality slider and a background colour for flattening transparency. Since JPG has no alpha channel, transparent areas take on the colour you pick — and the tool flags any PNG that's transparent so nothing changes behind your back.

Frequently asked questions
What happens to transparent areas?
They are flattened onto the background colour you select, because JPG cannot store transparency. The tool warns you when transparency is present.
What quality should I use?
Around 80–90 is a good balance of size and quality for most photos. Lower values save more space but reduce detail.
Is anything uploaded?
No. Conversion runs locally in your browser.
