Frequently asked questions
Grayscale vs black & white — what's the difference?
Grayscale keeps intermediate tones (readable photos); black & white forces each pixel to black or white, high-contrast photocopy style.
Does text stay selectable?
No: pages are converted to images to apply the filter. Keep the original if you need the text.
What is inverting colors for?
Reading dark-background documents, saving ink on dark designs, or making "night mode" versions.
Do I lose quality?
Pages render at 150 dpi — plenty for screens and home printing.
