pdf-craft Introduction

pdf-craft is a tool that can convert PDF files into other formats, focusing primarily on scanned book PDFs. It uses AI models and algorithms to extract text, filter out headers, footers, footnotes, and page numbers, and handles cross-page connection issues to generate coherent text.

Core Features:

• PDF to Markdown: Uses local computing power (CPU or GPU) to convert PDFs into Markdown files. Illustrations, tables, and formulas in the document will be inserted into the Markdown file as screenshots.
• PDF to EPUB: Converts PDFs into EPUB format. This process involves using local OCR to recognize text, then leveraging large language models (LLMs) to construct the book structure (such as table of contents), and integrate annotations and citation information. LLMs can also correct OCR errors.

Use Cases

The use cases for pdf-craft mainly revolve around converting PDF files into more readable and editable formats:

• Conversion of papers or small books: Converts PDF files of papers or small books into Markdown format for easy editing, modification, and secondary creation.
• Conversion of large books: Converts large book PDF files into EPUB format for better reading experience on e-readers, utilizing LLMs to build chapter tables of contents and integrate annotations.
• Digitalization of scanned books: Converts scanned book PDF files into text format for easy search, citation, and long-term storage.
• Scenarios requiring text extraction and structured information: In scenarios where text needs to be extracted from PDFs and converted into structured data (such as EPUB with a table of contents), pdf-craft can provide assistance.

In summary, pdf-craft aims to provide a convenient and efficient way to convert PDF files into other formats, especially when handling complex PDF files like scanned books, where its AI-driven features can significantly improve the quality and efficiency of conversion.
