Quick Start
Welcome to PDFLean. With 114+ professional PDF utilities, local tools execute inside your browser’s private memory sandbox — keeping your sensitive files on your device. Heavier tools are labeled Cloud and use our encrypted servers with short retention; each tool’s mode is clearly marked before you start. Five tools cover the most common document tasks — each opens its own dedicated page and runs in your browser with no account needed: pdf-merge · pdf-split · image-batch · PDF Linearizer (Fast Web View) · pdf-compressor.
