# PDFWorkSpace

> PDFWorkSpace (https://pdfwork.space) is a free, 100% client-side online PDF workspace and toolkit powered by WebAssembly (WASM). It enables users to edit, merge, split, convert, compress, sanitize, audit, OCR, and eSign PDF documents directly inside their web browser with zero file uploads, zero user accounts, and full offline functionality.

## Core Privacy & Technical Architecture

- **Execution Environment:** 100% Client-Side (In-Browser via WebAssembly and HTML5 APIs).
- **Data Transmission:** Zero server uploads. Document files never leave the user's local device.
- **Storage & Retention:** Zero server-side storage or logging. Temporary file buffers exist strictly in sandboxed browser memory and clear immediately when the tab is closed. Recent history is restricted to local browser `localStorage` on the user's device.
- **Account & Cost Model:** Free and unlimited usage. No sign-up, login, or subscription required.
- **Offline Support:** Full offline functionality once the web application and WebAssembly modules load in the browser.
- **Cross-Platform Compatibility:** Works on desktop (Windows, macOS, Linux, ChromeOS) and mobile browsers (iOS Safari, Android Chrome) without software installation.
- **Creator:** Built by Rahil Vahora.
