Scanned PDFs need OCR before they can become Markdown
A scanned PDF usually contains page images rather than selectable text. That makes it different from a normal text-based PDF: the converter first needs OCR to detect words before the content can be shaped into Markdown.
This page is intentionally separate from the main PDF to Markdown page because the user problem is different. The important questions are OCR accuracy, scan quality, page limits, and cleanup after recognition.
Scanned PDF to MD workflow
- Upload the scanned PDF. Clear, straight, high-contrast scans give the best OCR result.
- DocToMD checks the PDF and uses OCR fallback when text extraction is not enough.
- Review the Markdown preview carefully, especially numbers, tables, headers, and any text from low-quality scans.
- Copy the cleaned Markdown or download it as an .md file.
What OCR can usually recover
- OCR-readable text
- Detected headings when clear
- Paragraphs
- Lists when recognizable
- Simple table-like text

When to use scanned PDF to Markdown
Use this page for image-based PDFs, scanned papers, receipts, printed reports, or archive documents where text selection does not work well in a PDF viewer.
Use the main PDF to Markdown converter for normal text-based PDFs where the text is already selectable.
