PDF to Markdown

Drop in a PDF and get Markdown out — text, headings, and lists reconstructed in your browser. Copy it straight into a prompt or knowledge base, or download a .md file. The PDF is never uploaded.

Runs in your browser. Your input is not uploaded to PayloadIQ.

From a page layout to text a model can read

A PDF is built to look right on paper, not to be read by software. Open one in an LLM and you usually get a wall of broken lines, page numbers stuck mid-sentence, and headings that vanish. This converter walks the text layer of each page, rebuilds lines from the glyph positions, and promotes the larger type to # and ## headings — so what comes out is structured Markdown instead of a flat dump.

Why Markdown is the right format for AI

Markdown is the plain-text format that retrieval pipelines, prompts, and fine-tuning datasets all speak. It keeps the structure a model relies on — headings, bullet points, tables — while dropping the binary wrapper that would otherwise cost you tokens and confuse the context. Convert once, and the same .md drops cleanly into ChatGPT, Claude, a RAG index, or your docs.

Local, private, and free

Everything runs on your machine. The parser and its worker are served from PayloadIQ itself, so no part of your PDF is sent to a server here or anywhere else. Big files just take a moment — you'll see progress as the pages come through.

FAQ

Is my PDF uploaded anywhere?
No. The PDF is opened and parsed by your own browser using a local copy of the pdf.js engine. The file never leaves your device, so it's safe for contracts, invoices, and anything confidential.
Why convert a PDF to Markdown for AI?
Large language models read plain text, not page layouts. Markdown gives a model the headings, lists, and paragraph breaks it needs to follow your document, and it costs far fewer tokens than pasting a raw or badly-copied PDF dump.
Does it work on scanned PDFs?
Only if the PDF has a real text layer. A scanned or photographed page is just an image, so there is nothing to extract — that needs OCR, which we don't run here. If a page comes back empty, the tool tells you.
How are headings detected?
There are no headings stored in a PDF, so we infer them from font size: noticeably larger lines become Markdown headings. It's a good starting point, but skim the result and fix anything the layout fooled.
