PNG to JPG Converter

JPEG has no alpha channel, so transparent PNG pixels have to land on something — pick the background color they are flattened onto, set the quality, and convert as many files as you like at once.

Each result shows its dimensions and size change and downloads individually. Everything runs on a canvas in your browser.

Common uses

• Shrink large PNG screenshots into compact JPEGs
• Flatten transparent logos onto a brand color
• Convert design exports for systems that reject PNG

Limitations

• JPEG is lossy; fine text and sharp edges can pick up artifacts at low quality settings.

Do my PNG files leave my computer when I convert them?

No. The conversion runs on a canvas in your browser with no upload step at all — screenshots and design files stay on your device from start to finish.

What happens to transparency when I convert PNG to JPG?

JPEG has no alpha channel, so transparent pixels must be flattened onto a solid color. This tool lets you pick that background color; white is the default, but you can match a brand or page color instead.

How much smaller will my PNG be as a JPG?

For photos and screenshots the JPEG is often 70–90% smaller, because JPEG's lossy compression is built for continuous-tone images. The exact saving depends on the image content and the quality slider, which defaults to 90%.

When should I keep an image as PNG instead of converting?

Keep PNG when the image needs transparency, or when it contains sharp text, line art, or flat-color graphics — JPEG artifacts show most around hard edges. PNG is also the safer choice for images you will keep editing, since it loses nothing on each save.
