Frequently asked questions

No. AZ2PDF strictly adheres to international cryptography standards. Modern 128-bit and 256-bit AES encryption algorithms have no mathematical backdoors. The Unlock PDF tool removes viewing and editing restrictions only when you provide the valid document password.

For files exceeding 30MB, AZ2PDF automatically activates our asynchronous background queue. Enter your email address when uploading. Our server processes the document in the background and sends a secure, encrypted download link valid for 24 hours.

Scanned paper documents and photographed contracts are stored as flat bitmap pictures rather than selectable font characters. You must process the document through our optical character recognition (OCR) engine to synthesize an invisible, selectable text layer beneath the image.

Physical printers require mechanical non-printable edge margins (usually 3mm–5mm). If your PDF was created in US Letter and printed on European A4 paper (or vice versa), graphics placed close to page edges get clipped.

Yes. AZ2PDF is built from the ground up on a zero-data-retention architecture. We do not store personal data, track user identities, or retain files in long-term storage. All file buffers are strictly isolated in temporary memory and permanently destroyed by our automated cleanup system after 5 minutes.

Unlike traditional web apps that transmit your private files to remote cloud servers for rendering, our interactive PDF Editor runs 100% client-side inside your browser using WebAssembly. Your documents remain strictly inside your device's local RAM and are never transmitted over the internet.
