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.
