PDF to Markdown Online Free & Securely

Easily turn PDFs into Markdown files. Perfect for notes, docs, and LLMs. Headings, tables, lists, and links preserved automatically.

Upload your PDF and PDFSketch converts it to clean Markdown — preserving headings, tables, bullet lists, and links — ideal for notes, docs, or feeding into an LLM.

Structure detection runs on ephemeral servers to accurately map font and layout cues to Markdown syntax; source and output files are both discarded once your download completes.

How it works

  1. Upload your PDF — Select the document you want converted to plain-text Markdown.
  2. Structure detection runs automatically — Headings, tables, numbered/bulleted lists, and hyperlinks are identified and mapped to Markdown syntax.
  3. Download the .md file — Get a clean Markdown file ready for note-taking apps, documentation sites, or LLM context input.

Key features

  • Heading Structure Detection — Font size and weight cues are used to correctly map document headings to # / ## / ### levels.
  • Table Conversion — Simple tables convert to proper Markdown table syntax, not flattened plain text.
  • Link Preservation — Hyperlinks embedded in the PDF are kept as clickable Markdown links, not stripped out.

Quality checks before you finish
