Change the background color of your PDF for easier reading

Enhance Your Reading Comfort With Custom PDF Backgrounds

Reading PDF documents, especially for extended periods, can lead to eye strain, particularly with the default high-contrast white background and black text. Changing the background color of your PDF can significantly improve readability and reduce visual fatigue, offering a more comfortable experience. While typically a viewer-side setting for personal preference, there are also methods to permanently alter a PDF's background for sharing or printing.

Immediate Reading Comfort Adjusting Viewer Settings

The simplest and most common way to change a PDF's background for easier reading is through your PDF viewer's accessibility or display settings. These changes are local to your viewer and do not alter the original PDF file.

Adobe Acrobat Reader

Adobe Acrobat Reader provides robust accessibility options to customize document colors.

• Open your PDF in Adobe Acrobat Reader.
• Navigate to Edit Preferences (Windows) or Acrobat Reader Preferences (macOS).
• Select Accessibility from the Categories list.
• Check the box for Replace Document Colors.
• Choose Use High-Contrast Colors and select your preferred combination (e.g., White text on Black, Green text on Black, or Yellow text on Black).
• Alternatively, select Custom Color to define your own Page Background and Document Text colors.
• Click OK to apply the changes.

Google Chrome and Microsoft Edge Built In PDF Viewers

Modern web browsers often include integrated PDF viewers that leverage browser accessibility features.

• Open your PDF directly in Chrome or Edge.
• For Chrome, navigate to Settings Accessibility. Enable High-contrast mode or explore browser extensions designed for color inversion or custom themes.
• For Edge, similar accessibility settings can be found in Settings Appearance or by searching for "high contrast."
• These browser-level settings will apply to most content, including PDFs, offering a darker viewing experience.

Foxit Reader

Foxit Reader also offers straightforward display customization.

• Open your PDF in Foxit Reader.
• Go to File Preferences.
• Select Accessibility.
• Under "Document Color Options," check Change Document Colors.
• Choose a Custom Color scheme, setting your desired Page Background and Text Color.
• Click OK to save your preferences.

macOS Preview

Preview on macOS has limited direct background color alteration for PDFs. However, you can use macOS system-wide accessibility features.

• Go to System Settings Accessibility Display.
• Enable Invert Colors or Smart Invert (which intelligently inverts colors except for images and media).
• Alternatively, activate macOS Dark Mode (System Settings Appearance) for a system-wide dark interface, which can influence how Preview renders documents.

Permanently Modifying The PDF Document Background

If you need to share a PDF with a non-white background or require a permanent change within the file itself, viewer settings are insufficient. This requires editing the PDF's content. PDFs are fixed-layout documents, making direct background changes more involved than in word processors.

Approach 1 Convert To Editable Format Edit Then Convert Back

One effective method is to convert the PDF to an editable document format, modify its background, and then convert it back to PDF.

1. Convert PDF to Word: Use an online tool or desktop software to convert your PDF to a Microsoft Word document. This transforms the fixed layout into an editable text document. For a reliable conversion, you can use a tool like PDF to Word.
2. Change Background in Word: Open the converted .docx file in Microsoft Word. Go to Design Page Color and select your desired background color. Ensure the text color contrasts effectively with the new background.
3. Convert Word back to PDF: Save the Word document as a PDF. This new PDF will retain the background color you applied in Word.

Approach 2 Using A Dedicated PDF Editor

Professional PDF editing software provides more direct control over document elements, including backgrounds.

1. Open in Editor: Open your PDF file using a dedicated PDF editor (e.g., Adobe Acrobat Pro, Foxit PhantomPDF, or an online PDF editor).
2. Access Background Options: Look for features like "Edit Page Background," "Watermark," or "Header & Footer" where background color or images can be inserted.
3. Apply New Background: Editors typically allow you to add a new background color layer that appears behind existing content. You can usually choose a solid color and adjust its opacity.
4. Save Changes: Save the modified PDF. The background will now be an integral part of the document.
