FoxitPDFConversionSDKPython3 4.0.0

# Foxit Conversion SDK v4.0.0



Release Date: 30 September 2026



## Breaking Changes



### Node.js npm package name change



English-region documentation previously used an incorrect `@fuxinsoft/...` scope. For v4.0, install and `require`/`import` must use `@foxitsoftware/foxit-pdf-conversion-sdk-node`:



```bash

# v4.0

npm i @foxitsoftware/foxit-pdf-conversion-sdk-node

# or

yarn add @foxitsoftware/foxit-pdf-conversion-sdk-node

```



**Action required:** Replace the old package name, reinstall dependencies, and verify that Node.js samples and projects load the native module.



## New Features and Enhancements



### PDF ��� Markdown



- Add PDF-to-Markdown conversion via `foxit::conversion::pdf2md::PDF2Md::ConvertToMarkdown`, configurable via `PDF2MdSettingData` (table format, headers/footers, bold/italic retention, skipping scanned pages). Requires the `PDF2MD` module license.

- Add Markdown-to-PDF conversion via `foxit::conversion::md2pdf::Md2PDF::ConvertFromMarkdown`, configurable via `Md2PDFSettingData` (page size and margins, base font size, custom font path, style JSON, font embedding). Requires the `MD2PDF` module license.



### PDF to Office

# Foxit Conversion SDK v3.1.0



Release Date: 31 March 2026



## Breaking Changes 



### `PDF2WordSettingData` ��� Parameter change and default value change



Constructor and `Set()` method add a required `max_blank_paragraphs_per_page_bottom` parameter:



```cpp

// v3.0 (4 parameters)

PDF2WordSettingData(bool enable_retain_page_layout,

    bool enable_generate_headers_and_footers,

    bool enable_generate_footnotes_and_endnotes,

    bool enable_generate_page_rendered_break);



// v3.1 (5 parameters)

PDF2WordSettingData(bool enable_retain_page_layout,

    bool enable_generate_headers_and_footers,

    bool enable_generate_footnotes_and_endnotes,

    bool enable_generate_page_rendered_break,

    int max_blank_paragraphs_per_page_bottom);  // new

```



**Action required:** Add the new parameter when using the parameterized constructor or `Set()`. Pass `-1` for unlimited (matching previous behavior). Alternatively, use the default constructor with field assignment.



**Default value change** ��� `enable_generate_headers_and_footers` changed from `false` to `true`. Code using the default constructor will now generate headers and footers. Set `enable_generate_headers_and_footers = false` explicitly to preserve previous behavior.



### `PDF2PowerPointSettingData` ��� Parameter change



Constructor and `Set()` method add a required `enable_adapt_to_largest_page` parameter:



```cpp

// v3.0 (1 parameter)

PDF2PowerPointSettingData(bool enable_aggressively_split_sections);



// v3.1 (2 parameters)

PDF2PowerPointSettingData(bool enable_aggressively_split_sections,

    bool enable_adapt_to_largest_page);  // new

```



**Action required:** Add the new parameter. Pass `false` to preserve previous behavior.



### `PDF2ExcelSettingData` ��� Parameter change



Constructor and `Set()` method add 2 required parameters:



```cpp

// v3.0 (3 parameters)

PDF2ExcelSettingData(String decimal_symbol, String thousands_separator,

    WorkbookSettings workbook_settings);



// v3.1 (5 parameters)

PDF2ExcelSettingData(String decimal_symbol, String thousands_separator,

    WorkbookSettings workbook_settings,

    bool enable_aggressive_table_repair,  // new

    bool include_watermarks);             // new

```



**Action required:** Add 2 new parameters. Pass `true, false` to preserve previous behavior.



### `PDF2OfficeSettingData` ��� Parameter change



Constructor and `Set()` method add a required `enable_matching_system_fonts` parameter:



```cpp

// v3.0 (9 parameters)

PDF2OfficeSettingData(const wchar_t* metrics_data_folder_path,

    bool enable_ml_recognition, const Range& page_range,

    bool include_pdf_comments,

    const PDF2WordSettingData& word_setting_data,

    const PDF2PowerPointSettingData& power_point_setting_data,

    const PDF2ExcelSettingData& excel_setting_data,

    bool enable_trailing_space, bool include_images);



// v3.1 (10 parameters)

PDF2OfficeSettingData(/* same 9 parameters */,

    bool enable_matching_system_fonts);  // new

```



**Action required:** Add the new parameter. Pass `false` to preserve previous behavior.



### PDF-to-Word default behavior change



PDF-to-Word conversion now preserves document internal navigation links by default. If downstream workflows depend on link-free Word output, verify conversion results after upgrading.
