Why choose PNG over other formats?

PNG uses lossless compression, meaning no quality is lost during conversion. It preserves sharp text, clean lines, and supports transparency — ideal for documents and graphics.

Can I adjust the image resolution?

Yes. Use the scale slider to set the output resolution from 1x to 4x. The default is 2x (144 DPI), suitable for most use cases.

Will PNG files be larger than JPG?

Generally yes, because PNG uses lossless compression. However, for text-heavy documents, the difference is often minimal while the quality is noticeably better.

Does PNG support transparency?

Yes. PNG supports alpha transparency, so any transparent areas in your PDF will be preserved in the output images.

Can I convert a multi-page PDF?

Yes. Each page is converted to a separate PNG file that you can download individually.
