PDF to Markdown

About PDF to Markdown Converter

This tool converts PDF documents to Markdown format. It extracts text and automatically formats it with Markdown syntax including headings, lists, and paragraphs. For scanned or image-based PDFs, built-in OCR (Tesseract) reads the text in 10 languages including English, Vietnamese, Chinese, Japanese, Korean, French, German, Spanish, and Portuguese. You can also add a YAML front-matter block (title, author, date) so the output drops straight into Obsidian, Hugo, Jekyll, or MkDocs. All processing happens in your browser for complete privacy.

How does the conversion work?

The converter extracts text from each PDF page and analyzes font sizes and formatting to detect headings, bullet points, numbered lists, and paragraph structure. It then converts this into properly formatted Markdown syntax.

What Markdown elements are detected?

The converter can detect headings (based on font size), bullet points, numbered lists, and paragraph breaks. It preserves the logical structure of your document as much as possible.

Can I convert specific pages only?

Yes! You can choose to convert all pages or specify particular pages using page numbers (e.g., '1, 3, 5') or ranges (e.g., '1-5, 10-15').

What about images in the PDF?

Embedded images are not copied into the Markdown output, but their text is. For scanned or image-based PDFs, the tool automatically falls back to built-in OCR (Tesseract.js) to read the text directly in your browser. Just leave the OCR option enabled and pick the matching OCR language before converting.

Which languages does the OCR support, and how accurate is it?

Built-in OCR supports 10 languages: English, Vietnamese, Simplified and Traditional Chinese, Japanese, Korean, French, German, Spanish, and Portuguese. Accuracy is highest on clean, high-resolution scans with clear printed text; faint, skewed, or handwritten pages may need light manual cleanup. Pick the language that matches your document for the best results.

Can I import the output into Obsidian, Hugo, or GitHub?

Yes. Enable 'Add YAML front matter' to prepend a --- title / author / pages / source / date --- block to the .md file, which Obsidian, Hugo, Jekyll, and MkDocs read as page metadata. The Markdown body uses standard GitHub-flavored syntax (headings, lists, code fences), so it renders correctly on GitHub and in static-site generators without hand-editing.

Will the formatting be perfect?

The converter does its best to detect and preserve document structure, but complex layouts may require manual adjustments. Simple documents with clear headings and lists convert most accurately.

Is there a file size limit?

The maximum file size is 50MB. This ensures smooth performance in your browser. For larger files, consider splitting the PDF first.

Is my PDF file secure?

Absolutely! All conversion happens entirely in your browser. Your PDF file is never uploaded to any server, ensuring complete privacy and security.

Can I edit the output?

The Markdown output is provided in a text area that you can copy or download. You can then edit it in any text editor or Markdown editor of your choice.
