How to OCR a Scanned PDF and Make Its Text Usable

A scanned PDF is just a picture of a document — you can't select, copy, or search its text. Here's how to run OCR on it with AI.

A scanned PDF — one made from a photocopier, scanner, or a stack of photographed pages — looks like a normal document, but there's no real text underneath it. You can't select a sentence, search for a word, or copy a paragraph, because to the computer it's just an image. OCR fixes that by reading the image and giving you back real text.

When you need PDF OCR

  • A scanned contract, form, or report that you need to search or copy text from
  • An old document that only exists as a scanned image, not a digital original
  • A PDF built from photographed pages that you want to make text-searchable
  • Extracting the content of a scanned document to paste elsewhere

How to OCR a scanned PDF, step by step

  1. Open PDF OCR and sign in.
  2. Upload the scanned PDF — up to 12 pages are processed per document.
  3. Each page is rendered and read by the AI in one pass.
  4. Review the extracted text, organized page by page, in an editable box.
  5. Copy it, or download it as .txt, .pdf, or .png.

Tips for better OCR accuracy on scans

  • Higher-resolution scans OCR better. A crisp 300 DPI scan will read far more accurately than a low-resolution photo of a page.
  • Straighten skewed pages before scanning where possible — heavily tilted text is harder for any OCR engine to read reliably.
  • Split very long documents. Since processing is capped per document, split an especially long scan into smaller PDFs first with the PDF Split tool if it exceeds the page limit.

Common questions

Does this work on any scanned PDF? It works best on reasonably clear scans. Very low-resolution, heavily skewed, or badly damaged scans will read less reliably.

Is there a page limit? Yes — up to 12 pages are processed per PDF in one run. For longer documents, split them first.

Do I need to sign in? Yes, like all AI-powered tools, PDF OCR requires an account. Free accounts get 5 AI generations per day; Pro gets 100.

What if my PDF already has selectable text? You don't need OCR for that — regular PDF tools like PDF to Word will work directly and more accurately.
