How to Change the Background Color of a PDF (Free, Any Device)
Add a coloured background to a white PDF — cream, grey, sepia, or any custom colour. Easier on the eyes for long reading sessions. Free, browser-based.
Pure white PDF backgrounds cause eye strain during extended reading. Changing the background to a soft cream, warm grey, or sepia tone makes reading more comfortable without losing any content. FixMyPDF's background color tool does this free in your browser.
How to Change PDF Background Color
Go to fixmypdf.in/tools/background-color-pdf. Upload your PDF. Choose a preset background colour (cream #FFF8E7, sepia #F4ECD8, warm grey #F0F0F0, or any custom hex colour). Click "Apply Background". Download your more readable PDF.
Background Color vs Dark Mode Inversion
Adding a background colour keeps text black on a tinted background — ideal if you want reduced harshness while keeping a "light" reading experience. Dark mode inversion switches to white text on black — ideal for genuine dark theme reading. Background colour is gentler; inversion is more dramatic.
Best Colors for Reading Comfort
Cream (#FFF8E7 or #FFFACD) reduces contrast slightly while keeping text very readable — the most popular choice. Sepia (#F4ECD8) gives a warm paper-like feel. Light grey (#F5F5F5) is neutral and slightly cooler than cream. Avoid bright colours (red, blue, green) as backgrounds — they make text harder to read.
Permanent vs App-Level Background
Some PDF readers (like Adobe Reader) have a "Page Background" preference that shows a tinted background — but only in that app. Our tool modifies the PDF itself, so the tinted background appears in every PDF viewer, on every device, without any setting change by the recipient.
Adding Background to Printed PDFs
If you print a PDF with white pages, the background doesn't consume printer ink. If you apply a coloured background with our tool and then print, the printer will use ink for the background colour. For print purposes, keep background colour light (very pale cream or grey) to minimise ink usage.
Works on All Devices
The background colour tool works in any modern browser on Windows, Mac, iPhone, iPad, and Android. Open fixmypdf.in/tools/background-color-pdf on any device — no app installation needed.
After Changing the Background
Your more comfortable-to-read PDF is ready. Add a password if sharing a private document, or compress it — background colour adds minimal file size, so compression still applies to the image content.
