PNG to JPG

Convert PNG images to JPEG format for significantly smaller file sizes. Note that JPEG does not support transparency — transparent areas will be filled with white.

PNG to JPG conversion reduces file size by 60–80% for photographs because JPEG uses lossy compression optimised for photos. The trade-off: JPEG does not support transparency, so transparent areas are filled with a white (or custom) background.

Frequently Asked Questions

What happens to transparent areas?

JPEG does not support transparency. Transparent areas in your PNG will be filled with a white background during conversion.

When should I use JPG instead of PNG?

Use JPG for photographs and complex images where smaller file size matters more than transparency or pixel-perfect quality.

How much smaller will the JPG be?

For photographs, JPEG at 80–85% quality is typically 60–80% smaller than the original PNG. For graphics with large flat-color areas the savings are smaller because PNG already compresses those efficiently.

Is my image uploaded to a server?

No. Conversion runs entirely in your browser using the Canvas API. No image data is transmitted to any server.
