Changelog

All notable changes to PDF Dark Mode Converter.

v2.0.0 - April 14, 2026

New tool, smarter converter, 14 blog posts, and a proper site around it all.

Invert PDF Colors

New standalone tool at /invert-pdf-colors. Does true RGB inversion (every color flipped to its complement) instead of applying a theme. Same GPU pipeline, same privacy, separate page so you can bookmark whichever one you actually use.

Converter

• Image preservation - toggle it on and the converter detects photos in your PDF and leaves them alone while darkening everything else. No more inverted headshots.
• Selectable text - optional invisible text layer overlay so you can still search and copy from the converted PDF.
• Light mode output - you can now go dark-to-light too, not just light-to-dark. Handy for printing dark PDFs on paper.
• Toolbar colors now tint to match whichever theme you pick.

UI

• Replaced the plain theme dropdown with a custom picker showing color swatches for each theme.
• Added a color panel with hex input and a preset grid for the custom color option.
• Settings (resolution, quality, toggles) are now behind a collapsible panel instead of being always visible.
• Glassmorphism toolbar (translucent blur effect).
• Homepage now has a blog carousel you can drag-scroll through.
• Responsive across phone, tablet, and desktop.

Content

• 14 blog posts - platform guides for Chrome, Firefox, Edge, Windows, Android, iPhone, iPad, Google Drive, and Acrobat, plus topic pieces on inversion vs dark mode, printing, nighttime reading, and converting online.
• Full site translated into 10 languages: English, Spanish, French, German, Italian, Portuguese, Chinese, Korean, Japanese, Russian.
• About, Privacy, Terms, Contact, and this Changelog page.
• Shared footer across all pages.

Bug Fixes

• Fixed GPU filter detection for Firefox (canvas SVG filter fallback now works correctly).
• Improved mobile layout: language switcher no longer overlaps navigation, GitHub ribbon hidden on small screens, responsive toolbar spacing.
