PDFDesk is built as a client-side application. We utilize standard browser-based technologies (like PDF.js and pdf-lib) to compress, edit, convert, split, and merge your PDFs right on your machine. We do not have any remote backend servers for file processing, meaning it is technically impossible for us to view, store, or share your document data.
To improve user experience and monitor site health, we may collect anonymous usage metadata (such as page views, button clicks, and error reports) through third-party web analytics. This metadata does not contain any personal identification or document content.
We may use cookies and local browser storage to keep track of your preferences (such as tool settings) and to display non-personalized ads to support our free service. You can disable cookies at any time through your individual browser settings.
We may integrate standard, privacy-compliant third-party advertising partners and analytics platforms to keep PDFDesk 100% free. These providers may collect anonymized system identifiers to deliver services. Your document data is never exposed to these partners.
Since your documents stay inside your local browser tab and never transit across the internet to our servers, you are protected against server-side data leaks, database breaches, or unauthorized transmission. This is the absolute safest way to handle sensitive PDFs.
