## Private by design

Changes are made on your device, in memory. The original file is untouched and the new one is only created when you press the button.

## Good to know

Pages are redrawn as images, so text can no longer be selected. 150 dpi suits printing at home; use 300 dpi for small print.

## Questions

### Will it save printer ink?

Yes. Colour cartridges are not used, and pure black and white also removes grey backgrounds.

### Can I keep the text selectable?

Not with this tool. Most printers also offer a grayscale option in their print dialog.
