Claude-Skill-pdf-to-epub

This Claude Code skill automates PDF-to-EPUB conversion by analyzing document structure to detect chapters based on font analysis, extracting and compressing images for e-readers, and converting footnote references into clickable hyperlinks. It handles both single-column and multi-column layouts with configurable reading order detection and includes quality validation to verify text completeness and preserve reading order. The skill follows a four-phase workflow—analyze, convert, validate, and adapt—making it suitable for publishers managing digital content workflows and operations teams handling batch conversions. Configuration examples support fiction books, academic papers, and other document types.

[{"step":"Prepare your PDF file and note the required metadata (title, author, language). Ensure the PDF has clear chapter headings and footnotes for optimal conversion.","tip":"Use Adobe Acrobat or PDF-XChange Editor to check for hidden chapter markers or inconsistent formatting that might affect the EPUB structure."},{"step":"Run the conversion using the prompt template. Replace [PDF_FILE_PATH] with the local path to your PDF, and fill in the other placeholders (e.g., [TARGET_DPI]=150, [BOOK_TITLE], [OUTPUT_PATH]).","tip":"For batch processing, use a script to iterate over multiple PDFs. Example: `for file in *.pdf; do convert \"$file\" \"${file%.pdf}.epub\"; done` (adjust for your environment)."},{"step":"Review the output EPUB in a dedicated reader like Calibre or Adobe Digital Editions. Verify chapter structure, image quality, and footnote links.","tip":"Use Calibre's 'EPUB Editor' to manually adjust chapter titles or fix any formatting issues that the auto-detection missed."},{"step":"Validate the EPUB using the W3C EPUB Validator (https://validator.w3.org/epubcheck/) to ensure compliance with EPUB standards.","tip":"Fix any validation errors before distribution to avoid rejections from platforms like Amazon KDP or Kobo."},{"step":"Distribute the EPUB to your desired platforms (e.g., Amazon KDP, IngramSpark, or your own website). Consider adding DRM if required by your distribution strategy.","tip":"For e-commerce, use tools like PublishDrive or StreetLib to automate distribution to multiple retailers."}]
