pdf-craft converts PDF files into various other formats, with a focus on handling scanned book PDFs.

This project is based on DeepSeek OCR for document recognition. It supports the recognition of complex content such as tables and formulas. With GPU acceleration, pdf-craft can complete the entire conversion process from PDF to Markdown or EPUB locally. During the conversion, pdf-craft automatically identifies document structure, accurately extracts body text, and filters out interfering elements like headers and footers. For academic or technical documents containing footnotes, formulas, and tables, pdf-craft handles them properly, preserving these important elements (including images and other assets within footnotes). When converting to EPUB, the table of contents is automatically generated. The final Markdown or EPUB files maintain the content integrity and readability of the original book.

Starting from the official v1.0.0 release, pdf-craft fully embraces DeepSeek OCR and no longer relies on LLM for text correction. This change brings significant performance improvements: the entire conversion process is completed locally without network requests, eliminating the long waits and occasional network failures of the old version.

However, the new version has also removed the LLM text correction feature. If your use case still requires this functionality, you can continue using the old version v0.2.8.
