Client-Side PDF Security & Formatting Guide
Why privacy-conscious professionals, attorneys, and medical practitioners never use cloud PDF converters.
Is it safe to merge confidential contracts and invoices here?
Yes, 100%. Unlike conventional online PDF services (like Smallpdf or iLovePDF) that upload your legal and financial documents to remote servers, PrivToolbox processes every byte locally within your browser using WebAssembly. Your files never leave your device RAM, and no copies exist on any server.
What confidential information is stored inside PDF metadata?
PDF files created by Microsoft Word, Adobe InDesign, or macOS Quartz silently embed the author's real name, operating system username, software build versions, exact creation timestamps, and internal network file paths. Purging this metadata before sending contracts or resumes prevents unintentional data leaks and social engineering reconnaissance.
Can PrivToolbox merge password-protected or encrypted PDFs?
For security reasons, documents protected by owner passwords with extraction restrictions must first have their passwords removed by the owner before browser-level merging. Standard read-only PDFs without encryption can be freely merged, reordered, and sanitized.
Does merging reduce PDF visual quality or rasterize vector text?
No. PrivToolbox performs structural page-tree recombination at the binary object level. Vector fonts, high-resolution imagery, and embedded vector curves remain bit-for-bit identical to the source documents.
