Markanm
A reader designed for long PDFs.
The reader mounts a small window around the pages you view instead of rendering every page at once.
Keep off-screen pages light
Page virtualization and lazy page sizing help avoid loading the entire document into the visible interface.
Move through a document
Use the page controls and zoom tools to move around a PDF and return to your last reading position.
Performance depends on the PDF
Very large, scanned, or complex PDFs can still take time. A 2,000–10,000 page mobile performance target has not been validated on representative devices.
