PDF to Word Converter#

Purpose#

• Wraps the ComPDFKitConversion Python SDK into a reusable local conversion workflow, supporting PDF / image to Word, PPT, Excel, HTML, RTF, Image, TXT, JSON, Markdown, and CSV (10 output formats in total).

Agent Skills Standard Compatibility#

• This Skill uses an Anthropic Agent Skills-compatible directory structure: pdf-to-word-docx/.
• The entry point is SKILL.md; helper scripts are placed in scripts/.
• The document uses $ARGUMENTS and ${CLAUDE_SKILL_DIR} conventions for distribution and execution in Claude Code / Agent Skills-compatible environments.

Input / Output#

• Input: The target format ( word/ excel/ ppt/ html/ rtf/ image/ txt/ json/ markdown/ csv), the PDF or image path, and the output path are passed via Skill arguments or the command line. An optional PDF password and conversion parameters may also be provided.
• Supported input file types:
  • PDF files ( .pdf)
  • Image files ( .jpg/ .jpeg/ .png/ .bmp/ .tif/ .tiff/ .webp/ .jp2/ .gif/ .tga)
• Output: A file in the corresponding format ( .docx, .pptx, .xlsx, .html, .rtf, image, .txt, .json, .md, .csv), or a clear error message.

Prerequisites#

• Supports Windows and macOS.

• The conversion SDK must be installed first: bash

  pip install ComPDFKitConversion
  
  

• On first run, the script automatically downloads license.xml from the ComPDF server and caches it in the scripts/ directory: text

  https://download.compdf.com/skills/license/license.xml
  
  

• The script reads the <key>...</key> field from license.xml and uses that key for LibraryManager.license_verify(...) authentication — it does not pass the XML file path directly to the SDK.

• To use a custom license, place your own license.xml in the scripts/ directory; the script will use it directly without downloading.

• During SDK initialization, the resource directory is always set to the directory containing pdf-to-word-docx.py, i.e., the scripts/ directory itself.

• When --enable-ocr or --enable-ai-layout (enabled by default) is used, the Skill also requires scripts/documentai.model. If the file does not exist, the script will automatically download it from: text

  https://download.compdf.com/skills/model/documentai.model
  
  

• To reuse an existing model file, you can override the default model path via an environment variable: bash

  export COMPDF_DOCUMENT_AI_MODEL="/path/to/documentai.model"
  
  

Workflow#

1. Confirm the Python package is installed: bash

   python -m pip show ComPDFKitConversion
   
   

2. The script automatically downloads license.xml on first run; the scripts/ directory is used directly as the SDK resource path.

3. In Agent Skills / Claude Code environments, prefer using the Skill's built-in script path variable: bash

   python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" word input.pdf output.docx
   python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" ppt input.pdf output.pptx
   python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" excel input.pdf output.xlsx
   
   

4. For more control, append common parameters: bash

   python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" excel input.pdf output.xlsx --page-ranges "1-3,5" --excel-all-content --excel-worksheet-option for-page
   python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" word input.pdf output.docx --enable-ocr --page-layout-mode flow
   
   

5. On startup, the script ensures scripts/license.xml exists (downloading it automatically from the ComPDF server if missing), reads the <key> field for SDK authentication, and uses the scripts/ directory as the resource path.

6. If --enable-ocr or --enable-ai-layout (enabled by default) is active, the script checks whether scripts/documentai.model exists; if not, it downloads the file automatically before initializing the Document AI model.

7. Check the return code; if it is not SUCCESS, handle license, password, resource, model, or input file issues according to the error name.

documentai.model Download Optimization#

• The script preferentially uses the model file pointed to by COMPDF_DOCUMENT_AI_MODEL.
• The default model path is scripts/documentai.model.
• During automatic download, the file is first written to documentai.model.part and then atomically renamed to the final file upon success, preventing partial file corruption.
• On download failure, the script retries automatically with back-off intervals of 2s / 5s / 10s.

Invoking Directly as a Skill#

• In environments that support Agent Skills, the Skill can be called directly: text

  /pdf-to-word-docx word input.pdf output.docx
  /pdf-to-word-docx excel input.pdf output.xlsx --excel-worksheet-option for-page
  
  

• When the Skill receives arguments, it passes them through to the script as-is: bash

  python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" $ARGUMENTS
  
  

• If the environment does not support direct Skill invocation, fall back to a regular command-line call.

Supported Output Formats#

• word → calls CPDFConversion.start_pdf_to_word
• excel → calls CPDFConversion.start_pdf_to_excel
• ppt → calls CPDFConversion.start_pdf_to_ppt
• html → calls CPDFConversion.start_pdf_to_html
• rtf → calls CPDFConversion.start_pdf_to_rtf
• image → calls CPDFConversion.start_pdf_to_image
• txt → calls CPDFConversion.start_pdf_to_txt
• json → calls CPDFConversion.start_pdf_to_json
• markdown → calls CPDFConversion.start_pdf_to_markdown
• csv → reuses CPDFConversion.start_pdf_to_excel with table/Excel parameters to produce CSV-friendly output

Input Source Types#

• The script supports PDF and image as input sources. The SDK's start_pdf_to_* interfaces natively accept image files with no pre-processing required.

• By default, the script auto-detects the input type from the file extension:

  • .pdf → pdf
  • .png/.jpg/.jpeg/.bmp/.tif/.tiff/.gif/.webp/.tga → image

• You can also specify the source type explicitly: bash

  python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" word input.png output.docx --source-type image
  
  

• image -> * and pdf -> * share the same set of CPDFConversion.start_pdf_to_* interfaces; only the input file type differs.

Smart Defaults#

The script automatically adjusts certain parameters based on the input source and output format to reduce manual configuration:

TriggerAutomatic BehaviorUser-OverridableDescriptionInput source is an image (auto-detected or explicit --source-type image)Automatically enables --enable-ocrNo ( --enable-ocr uses store_true; there is no --no-enable-ocr)Text in images must be extracted via OCR; without OCR, output will contain only images and no textOutput format is HTML ( format = html)Automatically sets --page-layout-mode to box (box layout)Yes — passing --page-layout-mode flow explicitly overrides thisBox layout better preserves the original formatting in HTML; specify flow explicitly if flow layout is needed

When triggered, the script prints a notice to stderr, for example:

text

Auto-enabled OCR for image input.
Auto-set page layout mode to BOX for HTML output.

Parameter Default Value Rules#

• Parameters that default to True ( --enable-ai-layout/ --contain-image/ --contain-annotation/ --contain-page-background-image/ --auto-create-folder/ --json-contain-table/ --txt-table-format) use BooleanOptionalAction; pass --no-xxx to disable.
• Parameters that default to False ( --enable-ocr/ --formula-to-image/ --transparent-text/ --output-document-per-page/ --excel-all-content/ --excel-csv-format/ --image-path-enhance) use store_true; passing the flag enables them.
• All CLI parameter defaults are fully consistent with the SDK's ConvertOptions() defaults — omitting a parameter is equivalent to using the SDK's original default value.

PDF with OCR enabled (multiple languages)#

bash

python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" word input.pdf output.docx --enable-ocr --ocr-language chinese english japanese

Trial License and Usage Limits#

• The scripts/license.xml auto-downloaded from the ComPDF server is a Trial License, allowing a maximum of 200 conversions.

• The script uses a SHA-256 fingerprint to detect whether the current License is the default trial key; no usage limit applies when using any other License.

• After each successful conversion using the trial License, the script prints the current used/remaining count to stderr, for example: text

  Trial license: 5/200 conversions used, 195 remaining.
  
  

• When the trial limit is reached (200 conversions), the script refuses to convert and prompts the user to purchase a full License: text

  Error: Trial license usage limit reached (200 conversions). Please purchase a license at: https://www.compdf.com/contact-sales?utm_source=clawhub&utm_medium=skillhub&utm_campaign=pdf_skill_to_word&ref_platform_id=clawhub_skills
  
  

• When the trial License has expired (SDK authentication fails), the error message also includes a purchase link.

• After purchasing a full License, place a custom license.xml containing the new <key> in scripts/ (overwriting the auto-downloaded trial file) — no script modifications or counter file cleanup are required.

Confirmed Facts#

• ComPDFKitConversion has been successfully installed on the local machine.
• The installed package provides 10 conversion methods including CPDFConversion.start_pdf_to_word/start_pdf_to_ppt/start_pdf_to_excel.
• LibraryManager provides initialize, license_verify, release, set_document_ai_model, and set_ocr_language.
• Official documentation confirms support for PDF to Word / Excel / PPT / HTML / RTF / Image / TXT / JSON / Markdown.
• The SDK's start_pdf_to_* interfaces natively accept image file input (PNG → Word has been verified successfully).
• enable_ai_layout defaults to True in the SDK; set_document_ai_model() must be called first to load the model before use, otherwise a 0xC0000005 crash will occur.
• --ocr-language supports specifying multiple languages simultaneously (e.g. --ocr-language chinese english).

Risks / Notes#

• The official requirements page states Python >=3.6, while the demo page states <3.11, but PyPI currently provides a cp314 wheel in practice; treat the locally installable wheel as the source of truth, but always verify installation in a new environment first.
• If the script cannot download license.xml from the server (network issue) and no manual file exists in scripts/, or the <key> field is empty, the script cannot complete SDK authentication and cannot perform any real conversions.
• documentai.model is a large file (approximately 525 MB); there will be a noticeable download delay the first time OCR / AI layout is enabled. Because --enable-ai-layout defaults to True, the model download will be triggered on the very first run.
• If the runtime environment cannot access https://download.compdf.com/skills/model/documentai.model, place documentai.model in the scripts/ directory in advance.
• Do not directly apply the initialization patterns from ComPDF SDKs for other languages to the Python package; this Skill is based on the locally verified LibraryManager / CPDFConversion API.

Resource Navigation#

• Script: scripts/pdf-to-word-docx.py
• SDK authentication file: scripts/license.xml (auto-downloaded from https://download.compdf.com/skills/license/license.xml if missing)
• SDK authentication source: the <key> field in license.xml
• SDK resource path: scripts/
• OCR / AI layout model: scripts/documentai.model (auto-downloaded if missing)
• Purchase a full License: https://www.compdf.com/contact-sales?utm_source=clawhub&utm_medium=skillhub&utm_campaign=pdf_skill_to_word&ref_platform_id=clawhub_skills

Acceptance Checklist#

• python -m pip show ComPDFKitConversion shows the installed package
• Running python "${CLAUDE_SKILL_DIR}/scripts/pdf-to-word-docx.py" --help or an equivalent local command produces normal output
• The script auto-downloads scripts/license.xml if missing, then extracts the license key from the <key> field for authentication
• The script uses the scripts/ directory as the SDK resource path
• The script recognizes all 10 target formats: word/ excel/ ppt/ html/ rtf/ image/ txt/ json/ markdown/ csv
• The script accepts both PDF and image files ( .png/ .jpg/ .jpeg/ .bmp/ .tif/ .tiff/ .gif/ .webp/ .tga) as input
• When --enable-ocr or --enable-ai-layout (enabled by default) is active and documentai.model is missing, the script auto-downloads the model
• When license.xml cannot be obtained (download fails and no manual file exists) or authentication fails, a clear error is output rather than a silent failure
• The 7 parameters that default to True can be disabled with --no-xxx
• --ocr-language supports specifying multiple languages simultaneously
• After a conversion using the trial License, the usage count increments
• When the trial License reaches 200 conversions, the script refuses to convert and outputs a purchase link
• When using a non-trial License, no usage limit applies
• For image input, even if --enable-ocr is not passed, the script automatically enables OCR and prints a notice to stderr
• For HTML output, even if --page-layout-mode is not passed, the script automatically uses box (box layout) and prints a notice to stderr
• For HTML output, explicitly passing --page-layout-mode flow overrides the automatic box layout behavior

Distribution Notes#

• This Skill does not depend on any machine-specific absolute paths.

• When distributing to other users, the following directory structure is sufficient: text

  pdf-to-word-docx/
  ├── SKILL.md
  ├── License.txt
  └── scripts/
      └── pdf-to-word-docx.py
  
  

• Users place this directory under their own skills root directory and the Skill is ready to use.

• license.xml is auto-downloaded at runtime; no need to include it in the distribution package.

Common Pitfalls#

• scripts/license.xml is missing and cannot be auto-downloaded (network unavailable or server error): the script will error out before authentication. If you are in an offline environment, place license.xml manually in the scripts/ directory.
• scripts/license.xml is missing the <key> field or its value is empty: the script will error out before authentication.
• SDK resource files required by the SDK are absent from the scripts/ directory: conversion may fail after LibraryManager.initialize().
• A password-protected PDF is provided without --password: this will trigger PDF_PASSWORD_ERROR.
• OCR / AI layout is enabled but documentai.model is not present locally and the network is unavailable: the model download will fail; place the file in the scripts/ directory manually in advance.
• When the Excel output strategy is unclear, prefer passing --excel-worksheet-option explicitly to avoid unexpected result structures.
• When converting images to other formats, the script already enables OCR automatically; if the output still contains no text, check whether documentai.model is complete and whether the OCR language matches.
• Once the trial License usage limit is exhausted, a full License must be purchased to continue; purchase link: https://www.compdf.com/contact-sales?utm_source=clawhub&utm_medium=skillhub&utm_campaign=pdf_skill_to_word&ref_platform_id=clawhub_skills.
