Frequently Asked Questions

Q: What happens if I provide the wrong password for a protected Word file?
A: The API throws a PasswordException. Catch the exception and prompt the user to re‑enter the correct password.

A: Yes. Use the PdfSecurityOptions class to define user (open) and owner (permissions) passwords, as well as encryption level.

Q: Is it possible to add a watermark while converting?
A: Absolutely. The conversion options include a Watermark property where you can specify text, font, color, and opacity.

A: Yes. Loop through your file collection, apply the password for each, and invoke the conversion method. The library is thread‑safe for parallel processing.

Q: Are there any size limitations for the source Word documents?
A: The library itself imposes no hard limit, but memory consumption grows with document complexity. For very large files, consider streaming or increasing JVM heap size.
