The 3 server-assisted tools (Compress PDF, PDF to PDF/A, and Word to PDF) transfer files over TLS 1.3 encryption and delete them immediately after processing (with a 30-minute maximum fallback sweep).

We never sell, rent, or trade your data. For 19 client-side PDF tools and all 20 calculators, nothing ever leaves your browser. Only the Word to PDF tool transmits your .docx/.doc file to a third-party conversion processor (CloudConvert API) over HTTPS solely to render the PDF, after which it is automatically purged.
