How it works (privacy & technical)
Our PDF Editor operates entirely within your browser using pdf-lib 1.17.1 and PDF.js 3.11.174. PDF files are loaded as Uint8Array byte streams and processed in the browser’s memory, with operations such as PDFDocument.copyPages and getPage executed directly in the JavaScript engine. This ensures that your files are never uploaded to any server, thus avoiding any server logs or network transmission of your sensitive data. In contrast, server-based tools require file uploads, which can pose security risks and privacy concerns.
