Enterprise Privacy & Security
Your PDF files are processed securely in memory and never stored or used to train public LLM models.

Why convert PDFs to Markdown for LLM & RAG Pipelines?
- PDFs contain noisy formatting, absolute coordinates, and non-linear text streams that degrade LLM retrieval accuracy.
- Markdown preserves the structure a raw PDF text dump loses (headings, lists, tables), which lets a retrieval system chunk along real section boundaries.
- Vector chunking algorithms perform significantly better on Markdown headers (###) than arbitrary token splits.
What people use PDF to Markdown for
- Loading product manuals and installation guides into a support knowledge base so the bot answers from the manual instead of a summary of it.
- Moving signed contracts and policy documents into a wiki where they can be searched and linked rather than downloaded.
- Preparing analyst reports and whitepapers for a RAG index without carrying the two-column layout into the chunks.
- Checking whether a scanned or exported PDF has a usable heading structure at all before committing it to an ingestion pipeline.
- Turning a printed onboarding pack into Markdown that a static site generator can publish as searchable internal docs.

Frequently Asked Questions about PDF to Markdown
Is this PDF to Markdown converter completely free?
Yes, our PDF to Markdown tool is 100% free with no credit card, signup, or software installation required.
Will my PDF formatting, tables, and headers be preserved?
Yes. The layout analyzer detects semantic font sizes, bold weights, list bullets, and table columns, converting them into standard GitHub-flavored Markdown.
Are my uploaded PDF files kept private?
Yes. Files are processed securely in an isolated sandbox and deleted immediately after conversion. We do not log or store document contents.
Can I connect CustomerGPT to my PDF library automatically?
Yes! CustomerGPT supports automated document syncing. You can upload entire folders of PDFs or connect cloud storage in your CustomerGPT dashboard.
Does it work on scanned PDFs or images of text?
Only if the PDF contains a real text layer. A scan with no OCR applied has no extractable characters, so the converter has nothing to read. Run OCR first — most scanner software and PDF editors can add a text layer — then convert.
What is the file size limit?
Up to 25MB per file. Documents larger than that are usually collections rather than single documents, and split better along their own sections before conversion — which also produces cleaner retrieval chunks.
