PDF to LaTeX is a specialized web tool that converts PDF documents into LaTeX code using artificial intelligence. It works by first converting PDF pages into images, then processing these images through a multimodal large language model trained on extensive PDF-LaTeX pairs. The tool focuses on academic and technical documents, preserving mathematical equations, document structure, and formatting while converting content into editable LaTeX code.

The conversion process happens entirely in memory—files are never written to disk, addressing privacy concerns for sensitive documents. While the AI does its best to reproduce complex layouts, users should expect to make manual adjustments for very intricate documents. Images aren't copied directly but are referenced in the generated code, requiring users to handle image files separately. The tool operates on a credit system where users purchase page conversions in bundles of 10, 25, or 100 pages.

This tool serves researchers, students, and technical professionals who need to work with LaTeX documents but have source material in PDF format. It's particularly useful for converting published papers for republication, updating old technical documentation, or preparing academic submissions that require LaTeX formatting. The straightforward pricing and privacy-focused approach make it accessible for individual users and small projects.
