PDF to Markdown Converter
Turn a PDF into clean Markdown, ready for ChatGPT, Claude or your wiki.
How do I convert a PDF to Markdown for ChatGPT or Claude?
Drop your PDF into this tool and get clean Markdown back in seconds: headings are detected by font size, lists become bullets or numbered items, and reading order follows the original layout even across multi-column pages. It's free, requires no signup, and the file never leaves your browser — a WebAssembly engine runs the whole conversion locally, so you can process contracts or reports without uploading anything. Pasting a PDF straight into an AI chat usually scrambles columns, breaks tables, and flattens heading hierarchy; clean Markdown fixes that and typically uses fewer tokens than raw copy-pasted text full of stray line breaks. Pick between a fidelity profile that mirrors the source structure or a compact profile built to minimize token count. If the PDF has scanned pages with no extractable text, the tool flags exactly which pages those are — it doesn't run OCR, so that content simply won't appear in the output.
How to use PDF to Markdown Converter
- Drag your PDF into the upload zone or click to browse for it on your device.
- Pick an output profile: 'Source-faithful' keeps the document's original structure, 'Compact' trims tokens for pasting into an AI chat. Toggle page markers on if you need them.
- If the PDF is password-protected, enter the password in the optional field before converting — it's only used inside your browser.
- Click 'Convert to Markdown' and check the preview: you'll see the detected PDF type, a confidence score, and a warning if any pages are scanned images with no text.
- Copy the Markdown to your clipboard or download it as a .md file.
Common use cases
Pasting a long report into ChatGPT or Claude
Convert a 40-page report to Markdown before pasting it into a chat: headings and lists survive the trip, so the model understands the document's structure instead of receiving one undifferentiated block of text.
Migrating documentation from PDF into an internal wiki
Move technical manuals or internal policies from PDF to Markdown so they paste directly into Notion, Confluence, or a Git repo — no retyping headings and bullet lists by hand.
Prepping content for a RAG pipeline
If you're indexing documents for semantic search or a retrieval-augmented assistant, structured Markdown makes section-based chunking far easier than plain extracted text with no hierarchy signals.
Converting a multi-column PDF without scrambling reading order
Academic papers and magazine-style PDFs with two or three columns often get mixed up when you copy text directly; this tool reconstructs the correct column-by-column reading order.
Reviewing a confidential contract without uploading it anywhere
Since conversion happens entirely in your browser, you can turn contracts, financial statements, or legal documents into Markdown without the file ever leaving your machine.
Frequently asked questions
Why convert a PDF to Markdown instead of just copying and pasting the text?
Copy-pasting text out of a PDF usually breaks reading order in multi-column documents, blends headings into body paragraphs, and loses list structure. Markdown preserves headings, lists, and hierarchy, which helps both a human reader and an AI model understand the document.
Does it detect tables and convert them to Markdown format?
The engine identifies table and column structures when the layout supports it, but conversion of complex tables is approximate. Simple tables usually come out directly usable; heavily designed layouts may need a manual touch-up.
What happens if the PDF is a scanned document with no text layer?
The tool detects which pages are scanned images with no extractable text and flags exactly which ones, rather than inventing content. It doesn't run OCR — if you need text pulled from scanned pages, that's the honest limitation of this version.
What's the difference between the 'Source-faithful' and 'Compact' profiles?
'Source-faithful' reproduces the document's structure as-is, useful when you want to preserve the original design. 'Compact' reduces the token count of the output, aimed at pasting the Markdown into an AI chat with a limited context window.
Is it safe to convert a confidential PDF with this tool?
Yes. All processing happens in your browser via WebAssembly — the file is never uploaded to a server. You can even disconnect from the internet after the page loads and keep converting PDFs.
Does it work with password-protected PDFs?
Yes, there's an optional field to enter the PDF's password. It's used once, inside your browser, to read the file — it's never sent to any server.
