Select **Convert to Markdown**. 3. Review the headings, lists, links, and tables in the preview. 4. Copy the Markdown or download the result as a `.md` file. ## What the converter keeps A PDF stores a page layout. Markdown stores the structure of the writing. The converter rebuilds that structure as headings, paragraphs, lists, links, code, and tables where the source document makes them clear. Simple reports, papers, manuals, and exported documents usually convert cleanly. Multi-column pages, charts, forms, and heavily designed brochures can need a manual pass because their visual reading order is not always the same as their document order. ## PDF to Markdown for AI context PDF is useful for sharing a finished page, but awkward as working context. Markdown is smaller, searchable, editable, and easy for an agent to quote or split into sections. It also works in Git, local agent instruction folders, note systems, and plain text prompts without locking the content to one model. If the source lives on the web instead of in a file, use the [URL to Markdown converter](https://keep.md/tools/url-to-markdown). Once the text is clean, the [token counter](https://keep.md/tools/token-counter) shows how much context it will use in current AI models. ## When a PDF does not convert cleanly - Encrypted or damaged PDFs may not expose readable content. - Image-only scans need OCR before they can produce useful Markdown. - Complex tables can need column alignment fixes. - Headers, footers, and page numbers may appear in the Markdown if they are part of the PDF text layer. ## Frequently asked questions Choose a PDF, select Convert to Markdown, then review the result. You can copy the Markdown directly or download it as a .md file. The converter keeps readable headings, paragraphs, lists, links, and tables where the PDF structure makes them available. Yes. You can convert one PDF at a time without creating an account. Each file can be up to 15 MB. No. The public converter processes the file for this request and returns the Markdown. It does not add the PDF or converted text to your Keep library. If you want the document to become reusable context for your agents, you can add it to Keep separately. Not reliably. The converter reads the text and document structure already stored in the PDF; it does not run OCR over image-only pages. A scanned PDF needs searchable text added before conversion. The converter preserves headings, lists, links, and tables when it can detect them from the PDF. Multi-column layouts, charts, and heavily designed reports may need a quick manual tidy after conversion. The output is a Markdown document, not a folder of extracted image files. Text associated with an image may appear in the result, but the converter does not give you a separate download for every embedded image. Markdown removes page furniture and gives the agent a simpler hierarchy of headings, paragraphs, lists, tables, and links. That makes the content easier to inspect, quote, split into context, and keep under version control. Yes. Copy the result into a conversation, attach the .md file, place it in a project, or save it as shared context in Keep. Markdown is portable across Claude, ChatGPT, Codex, Cursor, and other agent tools. ## Related tools [ ### URL to Markdown Convert any webpage into clean, AI-ready Markdown.
