How do I convert JPG to PNG?

Upload your JPG to Master Merge's JPG to PNG converter and click Convert. A PNG file downloads instantly.

Will PNG be larger than the JPG?

Usually yes — PNG is lossless and uncompressed-style, so file sizes are typically larger than JPG. The trade-off is perfect quality.

Can the PNG have a transparent background?

JPG doesn't support transparency, so the source image has none to convert. To add transparency, use an image editor after conversion.

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.
