PDF Viewer

I'll help you create a comprehensive PDF viewer! Here's a complete implementation using PDF.js with a modern interface. The viewer includes a navigation sidebar with thumbnail previews and document outline, zoom controls (25%-400%), text search with highlighted results across all pages, and annotation tools for highlighting and adding notes. I've implemented rotation, fullscreen presentation mode, and responsive design that adapts to mobile devices, along with a print dialog and metadata viewer for document properties.

I can help you build this PDF viewer, though I should note that a full implementation would be quite extensive. I'll provide the core structure using PDF.js for rendering, a responsive layout with sidebar navigation, and implement the key features like search, zoom, and basic annotations. For production use, you'd want to add error handling, test across browsers thoroughly, and consider performance optimization for large PDFs—PDF.js can be memory-intensive with complex documents.

Here's a web-based PDF viewer implementation using Mozilla's PDF.js library (v3.11). The code includes a dual-pane interface with thumbnail sidebar, text search using PDF.js's TextLayer API for highlighting matches, zoom controls (fit-width, fit-height, custom percentages), and Canvas-based annotation overlays. The viewer supports touch gestures for mobile, implements Web Print API for printing, and extracts metadata using PDFDocumentProxy.getMetadata(). Total implementation is approximately 800 lines across HTML/CSS/JS files.
