Frequently asked questions
What's the difference between Dark mode and Negative?
Dark mode flips light and dark but keeps colours, so a red heading stays red. Negative inverts every colour, like a photo negative.
Why can't I select text in the new PDF?
Each page is redrawn as an image with new colours. Keep the original PDF if you need to copy or search text.
Is it good for studying at night?
Yes. Dark pages cut screen glare; Night sepia is gentler still for long reading sessions.
Is my PDF uploaded?
No. Conversion happens in your browser.
