PDF viewer

This tool provides a browser-based PDF viewer that accepts sources via URL or file upload and renders the document for immediate viewing. It supports password-protected PDFs by accepting a password and rendering once authentication succeeds. The rendering is designed for quick access across desktop, tablet, and mobile devices, prioritizing privacy and minimal setup. Conceptually, the viewer relies on a standard PDF rendering engine that parses pages, computes total_pages, and presents the requested page at an appropriate zoom level. The system emphasizes non-destructive behavior: no editing, annotation, or text extraction is performed during viewing. Core benefits include reduced software installation, cross-device compatibility, and a focus on reading fidelity. Typical use cases include students reviewing course PDFs, researchers inspecting papers, and teams sharing reference documents in meetings. Unique value comes from simple inputs (URL or file), password support, and fast, predictable rendering without backend document processing. Core features are input flexibility, password handling, page navigation, and variable zoom, all accessible through a clean, serverless workflow. The tool is especially suited for quick document checks, reading during travel, or onboarding new team members who need immediate access to materials.
