 ### Step 1: Define Conversion Path and Load Options

+setDefaultFont specifies the fallback font used when the original is missing.
+setFontSubstitutes maps unavailable fonts to alternative fonts you provide.

 ```
 
+#### Direct Answer
+Set `setAutoFontSubstitution(false)` to disable automatic guesses, then provide a reliable fallback with `setDefaultFont("Helvetica.ttf")`. Finally, map any missing fonts to known alternatives using `setFontSubstitutes(...)`. This ensures every character in the source DOCX has a matching glyph in the output PDF.
+
 #### Explanation
 - `setAutoFontSubstitution(false)`: Turns off the library’s automatic guesswork, giving you full control.  
 - `setDefaultFont("Helvetica.ttf")`: Provides a universal fallback when a requested font isn’t found.  
 - `setFontSubstitutes(...)`: Maps missing fonts to alternatives you know are available on the target system.

 Now create the PDF‑specific options object.

+#### Direct Answer
+Instantiate `PdfConvertOptions`, optionally enable font embedding with `setEmbedFonts(true)`, and adjust compression settings to balance file size and quality. These options let you fine‑tune the final PDF to meet both visual fidelity and storage constraints.
+
 You can extend `PdfConvertOptions` later to tweak page size, margins, or compression settings.
 
 ### Step 3: Perform the Conversion
 Finally, run the conversion with the previously defined load and convert options.
+convert(source, target, loadOptions, pdfOptions) executes the conversion with the given settings.
 
 ```java
 // Convert Word document to PDF with specified font settings
 converter.convert(convertedFile, () -> loadOptions, options);
 ```
 
+#### Direct Answer
+Call `converter.convert(sourcePath, targetPath, loadOptions, pdfOptions)`. The API reads the DOCX, applies your font rules, embeds the chosen fonts, and writes a PDF that preserves the original typography exactly as intended.

 ## Performance Considerations
 - **Memory Management** – Large DOCX files can consume significant heap; monitor JVM memory and consider `-Xmx` adjustments.

 ## Common Issues and Solutions
 | Issue | Solution |
 |-------|----------|
 | Fonts not substituted | Verify that the font files exist at the paths you provided and that the `FontSubstitute` names match the exact font family names in the source DOCX. |
 | Out‑of‑memory errors | Increase JVM heap size (`-Xmx2g` or higher) or process files in smaller batches. |
 | PDF missing embedded fonts | Ensure `setDefaultFont` points to a TrueType (`.ttf`) or OpenType (`.otf`) file and that the license allows font embedding. |
+| Incorrect page layout after conversion | Use `PdfConvertOptions.setPageSize(...)` to match the original Word page dimensions. |
+| Slow conversion for very large files | Enable streaming mode with `PdfConvertOptions.setStream(true)` to reduce memory pressure. |
