Built Around Browser-Based Workflows
A central design principle of PDFZento is on-device client execution. For our standard suite of local PDF utilities, document parsing, page extraction, image compression, and PDF compilation execute locally inside your web browser using WebAssembly and Web Workers.
For these local tools, document files and extracted document content are processed on your device and are not uploaded to PDFZento servers or third-party processing services. Active application memory references are released when you close or reset the browser tab. Because browser caching, operating system memory paging, crash recovery, downloads, and third-party extensions remain under your device's environment, we advise users to maintain appropriate security hygiene on their local systems. For detailed technical architecture and data practices, please review our Privacy Policy.
