Convert PDF to Markdown Offline
The PDF to Markdown tool uses intelligent text extraction to parse your PDF documents and convert them into clean Markdown format. Unlike simple text extractors, this tool attempts to reconstruct headings and paragraph breaks by analyzing the font sizes and positions of the text within your document.
Complete Data Privacy
Because the conversion logic runs entirely on your device via JavaScript and WebAssembly (using PDF.js), your PDF is never uploaded to an external server. This guarantees absolute privacy for confidential reports, ebooks, or internal documentation.
How does it detect Markdown formatting?
Our algorithm scans the first few pages of your document to determine the most common font size (the "body" text). As it processes the rest of the document, any text that uses a significantly larger font size is automatically tagged as a Heading 1 (#), Heading 2 (##), or Heading 3 (###). It also detects horizontal gaps to infer paragraph breaks.

Key Concepts
Essential terms and definitions related to PDF to Markdown.
Heuristics
In software, a problem-solving approach that employs a practical method not guaranteed to be optimal or perfect, but sufficient for immediate goals. This tool uses heuristics (like checking font size) to guess document structure.
Frequently Asked Questions
How does this differ from the PDF to Text tool?
The PDF to Text tool simply dumps all raw text sequentially. This tool attempts to analyze font sizes, positions, and spacing to reconstruct the document structure, formatting headings (H1, H2) and lists in Markdown syntax.
Will tables be converted perfectly?
Extracting tabular data from PDFs into Markdown tables is notoriously difficult because PDFs do not have a concept of "tables"—only lines and text placed at specific coordinates. Complex tables may not convert perfectly.
Why use Markdown?
Markdown is a lightweight markup language that is easy to read in plain text. It is the preferred format for feeding documents into Large Language Models (LLMs) like ChatGPT or Claude, as it provides structural context (headings, lists) that raw text lacks.
Troubleshooting & Technical Tips
Common errors developers encounter and how to resolve them.
Headings are not recognized
The tool uses heuristics based on font size to detect headings. If the PDF uses the same font size for headings as for body text, the tool cannot distinguish them.
