PDFListo — Private Client-Side PDF Tools

100% private, client-side PDF tools. Merge, compress, split, and convert PDFs directly in your browser with zero server uploads.

PDFListo is a 100% private, client-side document utility designed for users who prioritize confidentiality, speed, and data sovereignty. Unlike traditional PDF web services that secretly transmit your sensitive files to third-party cloud servers, PDFListo operates entirely inside your browser's local memory (RAM). Your files NEVER leave your machine. ⚡ CORE IN-BROWSER TOOLS: • Merge PDF: Combine multiple PDFs and images into a single document with custom ordering. • Compress PDF: Reduce document file sizes using client-side WebAssembly optimization without losing readability. • Split PDF: Extract selected page ranges or separate multi-page documents instantly. • PDF to JPG: Convert PDF pages into crisp, high-resolution images in seconds. • Protect / Lock: Secure confidential files using local client-side 256-bit encryption. 🔒 MATHEMATICAL PRIVACY ASSURANCE: • Zero Server Uploads: 0 bytes transferred over the network. • RAM-Only Execution: Built with WebAssembly and PDF-lib. Files exist only in volatile RAM while being processed. • Completely Permissionless: The extension requires ZERO special browser permissions (no tab reading, no browsing history access, no background tracking). • Works Offline: Fully operational even when disconnected from the internet. • Compliance Ready: Perfect for legal, medical, and financial professionals who must adhere to strict HIPAA, GDPR, NDA, and confidentiality standards.
