Built for Privacy. Built for You.
PDFBuilt is a suite of free PDF tools that process your documents entirely inside your browser. No cloud. No uploads. No compromises.
How PDFBuilt Works
100% Client-Side Processing
Every PDF operation — merging, compressing, converting — runs entirely in your web browser using JavaScript and WebAssembly. Your files never leave your device.
Zero Server Storage
Unlike traditional PDF tools that upload your files to remote servers, PDFBuilt keeps everything local. When you close the tab, all data is gone — permanently.
Powered by Modern APIs
We leverage pdf-lib for document manipulation, PDF.js for rendering, and the Canvas API for image processing. No plugins or downloads required.
Works Everywhere
PDFBuilt works on Chrome, Firefox, Safari, and Edge — on desktop, tablet, and mobile. No installation needed.
Privacy by Design
We built PDFBuilt with a privacy-first architecture. We don't track your files, can't see your documents, and have no access to your data.
Free Forever
PDFBuilt is supported by non-intrusive ads. We believe essential PDF tools should be accessible to everyone, without paywalls or account requirements.
Our Technology Stack
PDFBuilt is built with modern, open-source technologies designed for performance and privacy.
