Privacy-First Architecture — Secure Local & High-Fidelity Hybrid Engine
Free PDF Tools Online
Merge, Compress, Convert & Edit PDFs
Merge, split, edit and watermark PDFs and images right in your browser — those files never leave your device. Compression, Office conversion and advanced OCR use a secure processing service, and every tool page says which it is.
Animated illustration: two PDF pages merge into one document, the document is compressed from 8.4 MB to 1.2 MB, scanned by OCR to recognize its text, then signed — all inside a browser window, showing that files never leave your device.

Under the hood
Hybrid Privacy & Processing Architecture.
Most tools run entirely in your browser. The conversions that need a server are sent to a secure processing service.
Web Worker isolation
Local PDF operations (Merge, Split, Rotate) run in dedicated worker threads. The browser stays completely responsive even during large document tasks.
Hybrid Privacy Design
Core tools process files entirely in-browser. Advanced format conversions run on secure servers where files are immediately deleted post-processing.
Layout-Aware PDF Conversion
Convert PDF to Word, Excel, and PowerPoint. Our enterprise layout engine preserves tables, text styling, margins, and vector graphics perfectly.
Transferable ArrayBuffers
Client-side results use zero-copy buffer transfer for instant local delivery without serialization overhead, delivering lightning-fast speeds.
AI Author Pipeline
Write in Markdown, export as a polished professional PDF. Powered by React-PDF with custom typography, spacing, and layout templates.
Tier-Gated Security
Free tools for standard workflows. Premium converters and the advanced PDF Editor are protected by secure tier-gated server middleware.
