Nothing is sent to a Markdown Lens server.
Editable output
Review the generated Markdown immediately in the built-in editor.
Take it anywhere
Copy Markdown, download .md, export HTML, or print the preview to PDF.
Three simple steps
How it works
- 1
Choose a PDF
Open a text-based PDF from your device. The file is handed directly to the browser and is never posted to a Markdown Lens backend.
- 2
Extract page by page
Markdown Lens reads selectable text, groups lines into paragraphs, detects likely headings and lists, and marks each original page.
- 3
Review and export
Edit the generated Markdown beside a rendered preview, then copy it, download .md, export HTML, or print the result.
What the PDF converter preserves
PDF is a visual format, so conversion is necessarily interpretive. Markdown Lens focuses on producing readable source that is easy to review instead of pretending to reproduce every pixel.
Document and page structure
The filename becomes a document title, page boundaries become Markdown comments and horizontal separators, and empty pages are identified clearly.
Headings, paragraphs, and lists
Font-size differences help infer heading levels. Bulleted and numbered lines become Markdown lists, while wrapped lines are joined into readable paragraphs.
Code-like text and web links
Text set in common monospaced fonts is placed in fenced code blocks. Visible URLs are linked, and additional PDF web links are listed by page.
Cleaner repeated margins
Repeated headers, footers, and standalone page numbers are removed when they can be identified consistently across pages.
Useful for real documentation work
Confluence exports
Turn a text-based Confluence PDF export into a Markdown draft for migration, cleanup, or reuse in a knowledge base.
Product and engineering specs
Recover headings, paragraphs, lists, code-like text, and links from specs that need to return to an editable format.
AI-ready source material
Create reviewable plain-text source for documentation systems, repositories, and retrieval workflows without sending the original file away.
Quick answers
Frequently asked questions
Is this PDF to Markdown converter free?
Yes. Markdown Lens is free and open source, requires no account, and does not add watermarks to the generated Markdown.
Does Markdown Lens upload my PDF?
No. PDF parsing, text extraction, Markdown conversion, editing, and draft autosave happen locally in your browser. The document is not sent to a Markdown Lens application server.
Can it convert a scanned PDF to Markdown?
Not directly. Scanned PDFs contain images rather than selectable text, and Markdown Lens does not perform OCR. Run OCR in a trusted tool first, then convert the resulting text-based PDF.
Will the Markdown look exactly like the PDF?
No. Markdown represents document structure rather than fixed visual layout. The converter aims for editable headings, paragraphs, lists, links, code-like blocks, and page boundaries; complex tables and visual positioning may require cleanup.
