How do I convert PNG to JPG?

Upload your PNG to Master Merge's PNG to JPG converter and click Convert. A JPG file downloads instantly, typically much smaller than the original PNG.

What happens to transparent areas?

JPG doesn't support transparency, so transparent PNG areas are flattened to a white background.

How much smaller will the JPG be?

Typically 50–90% smaller than the source PNG, depending on image content.

Are my files uploaded to a server?

No. Master Merge processes every file directly in your browser using JavaScript. Nothing is uploaded, stored, or transmitted to any server. This is the most private way to handle sensitive documents online.

Is this tool really free?

Yes — 100% free with no signup, no credit card, no email, no watermarks, and no hidden limits. We do not run ads or sell data. Use it as much as you want.

About Convert PNG to JPG
