PDF to Markdown

Upload your PDF using the form above, click convert, and copy the Markdown output into your ChatGPT prompt. Markdown uses fewer tokens than the same text inside a PDF, so you can fit longer documents inside ChatGPT, Claude, or Gemini's context window before hitting the limit.

No — scanned PDFs are just images of text and need OCR (optical character recognition) first. If your PDF returns a 'Could not extract enough text' error, it's almost certainly a scanned document. Run it through an OCR tool like Adobe Acrobat's OCR, Tesseract, or an online OCR service first, then bring the resulting text-based PDF back here.

No. The PDF is processed server-side in memory and discarded immediately after the response. We log a non-identifying request fingerprint (IP + UA hash) for rate-limiting and abuse prevention, plus the file size and text length for analytics, but never the file or the extracted text.

10 MB per upload, which covers the vast majority of business PDFs — a typical 100-page text-heavy report is well under 5 MB. Files with embedded images and scans inflate quickly; if your PDF is mostly images, strip them first or split into sections.

Copy-paste preserves nothing — you lose paragraph breaks, double-spacing, hyphenation cleanup, and table structure. This tool runs proper PDF parsing, normalizes whitespace, and removes the artifacts that make copy-pasted PDF text awful inside an LLM prompt.

Yes — many BuiltABot customers convert product manuals here, then paste the Markdown into their bot's knowledge base. If you have multiple PDFs and want it automated, BuiltABot ingests PDFs directly during setup and runs RAG over the extracted text for grounded answers.
