FAQ

Frequently Asked Questions

Technical questions about recoloring white PDF paper backgrounds, reducing eye strain with Sepia or Mint tints, and keeping text razor-sharp.

1How do I change the background color of a PDF without making text blurry?
Upload your PDF and choose Paper Tint (Multiply) mode. Instead of placing a semi-transparent box over your text—which washes out black letters—our studio multiplies the paper tint with white background pixels while applying a contrast boost so dark ink stays completely sharp.
2What is the best PDF background color to reduce eye strain?
Eye-Care Sepia (#FBF0D9), Warm Ivory Cream (#FDFBF7), and Soft Mint Green (#DCFCE7) are the most popular tints for long study sessions because they cut blue-light glare while preserving high reading contrast.
3Can I convert a white PDF into Dark Mode with light text?
Yes. Select the Dark Night Slate (#0F172A) or Blueprint Navy (#172554) preset, or switch the blend mode to Dark Mode (Light Ink). This maps bright white paper to a deep dark shade and turns black text into crisp light text.
4Can I apply different background colors to specific pages?
Yes. Switch the Color Application Scope in the left sidebar from 'All Pages' to 'Page Only' to assign custom background colors to individual cover pages, chapter dividers, or appendices.
5Will the new background color stay visible when I open the PDF in Adobe Acrobat or on an iPad?
Yes. Unlike temporary reader themes, the exported PDF has the new background color permanently baked into every page, so it looks identical in Adobe Acrobat, Apple Books, GoodNotes, Notability, and web browsers.
6Are my PDF files uploaded to a cloud server when changing background colors?
No. All page rendering, pixel recoloring, and PDF reconstruction happen 100% locally inside your browser for complete privacy.
