+  - question: Can I convert multiple documents in parallel?
+    answer: Yes. Create a thread pool and invoke the `run()` method for each file;

+  - question: What if my FTP server requires explicit TLS/SSL?
+    answer: Use `FTPSClient` from Apache Commons Net instead of `FTPClient` and adjust

+  - question: Are there any limits on the number of concurrent conversions?
+    answer: The limit is primarily bound by your server’s CPU, memory, and the licensing

-Converting FTP to PDF means downloading a file stored on an FTP server and transforming it into a PDF document without first saving it to disk. This eliminates I/O overhead and simplifies automated workflows.
+Converting FTP to PDF means downloading a file stored on an FTP server and transforming it into a PDF document without first saving it to disk. This eliminates I/O overhead, reduces storage usage, and simplifies automated workflows where documents must be rendered on‑the‑fly for compliance or preview purposes.
 
 ## Why use GroupDocs.Conversion for Java?
-- **Zero‑dependency conversion** – supports over 200 formats out of the box.  
-- **Stream‑based API** – works directly with `InputStream`, perfect for FTP scenarios.  
-- **Fine‑grained PDF options** – page size, margins, security, and more.  
-- **Enterprise‑ready licensing** – scalable for both small utilities and large back‑end services.
+Load‑time conversion is handled in‑memory, and the library supports **200+ formats**—including DOCX, XLSX, PPTX, HTML, and images—so you rarely need another tool. Its **stream‑based API** accepts `InputStream` directly, perfect for FTP scenarios. `PdfConvertOptions` is a configuration class for PDF settings such as page size, margins, and compliance. It also allows fine‑tuning of security and PDF/A options, giving you control over the final document.

+### Direct answer
+GroupDocs.Conversion for Java lets you convert any supported document to PDF by feeding it an `InputStream` from an FTP server; the library processes the stream in memory, applies optional PDF settings, and writes the result to an `OutputStream`—all without touching the local file system.
