Key Features
Hands-Free Auto-Scrolling
Read PDFs smoothly without scrolling manually. Fully customizable speed control in small steps of 10 px/s. Easily scroll down or up by reversing the speed.
100% Privacy Secure
All processing happens locally on your browser CPU using pure client-side technology. Your files are never uploaded to any server. Completely safe for private documents.
Cross-Platform Responsive Layout
Optimized for Windows, Mac, Linux, Android, and iOS. Add it to your phone's Home Screen to launch standalone like a native app.

Advanced Shortcuts & Controls
Adjust scrolling speed dynamically using Ctrl + Up/Down arrows (or Command on Mac) and arrow keys. Instant zoom options (fit width, zoom percentages).
High-Fidelity Text Copying
No flat images here. Select, double-click, and copy texts from the PDF document directly even while auto-scrolling is active.
