Check the preview: white becomes black and black becomes white.
Press “Invert colours” and download the dark version.
Frequently asked questions
Is the text still selectable?
Yes. Colours are inverted by a layer the PDF reader applies, so text, links and searching keep working.
What happens to photos and colours?
They turn into their opposite colours, like a photo negative. For reading text at night that is usually fine.
Can I invert only some pages?
Yes. Under “More options”, enter the pages to invert.
Should I print an inverted PDF?
Better not: a black page uses a lot of ink. Inverting is meant for screens.
Are my files uploaded to a server?
No. This tool runs entirely in your browser, so your files stay on your device and are never sent anywhere. It even works with the internet switched off.
