PNG to JPG Converter
Make PNG screenshots, photos and graphics small enough for email, forms and websites. Pick the quality and what transparent areas turn into.
Your files are processed in this browser tab and never leave your device.
PNG stores every pixel without loss, which is perfect for editing but heavy for sharing. A full-screen screenshot or an exported photo can easily be 5–10 MB as PNG and well under 1 MB as JPG with no visible difference.
JPG has no transparency, so this converter lets you choose what transparent areas become: white for documents and product photos, or black for dark-themed designs. Without that step, many tools turn transparency into an ugly black box.
Everything happens in your browser. Your screenshots — which often contain chats, emails or dashboards — are never uploaded anywhere.

Frequently asked questions
How much smaller is a JPG than a PNG?
For photos and screenshots, a JPG at 85–92% quality is typically 5 to 10 times smaller than the PNG. Simple graphics with flat colors and sharp text shrink less and may show slight fuzziness around letters.
What happens to transparent parts of the PNG?
JPG cannot store transparency, so transparent pixels are filled with the background you choose — white by default. Semi-transparent edges blend smoothly into that color.
Which quality setting should I use?
92% is a safe default that looks identical to the PNG. 80% is fine for web pages and chat. Go below 70% only when a site has a strict file size limit, as blocky artifacts start to show.
Should I convert logos and icons to JPG?
Usually not. Logos with transparency or crisp edges look best as PNG or SVG. Convert to JPG when the image is a photo or screenshot and file size matters.
