How to Convert Scanned PDF to Text (OCR)

A scanned PDF is essentially a collection of images — the text you see is not actually text data, just pixels arranged to look like letters. This means you cannot search, select, or copy text from a scanned PDF without first running OCR.

OCR (Optical Character Recognition) analyzes the image, identifies letter shapes, and creates a text layer that matches the visual content. YourPDF.tools runs OCR directly in your browser — no server upload needed.

Key Takeaways

  • •Scanned PDFs contain images, not text — OCR extracts the text data.
  • •Browser-based OCR means your scanned documents stay on your device.
  • •After OCR, the PDF becomes searchable and the text can be copied.
  • •Best results come from high-quality scans with clear, high-contrast text.

How to OCR a Scanned PDF

  1. Open the OCR PDF tool. Go to yourpdf.tools/ocr-pdf.
  2. Upload your scanned PDF. Drop the file into the upload area.
  3. Wait for OCR processing. The tool analyzes each page and identifies text characters.
  4. Review the results. Check the extracted text for accuracy.
  5. Download the searchable PDF. The output PDF contains a text layer behind the images, making it searchable and copyable.

Tips for Better OCR Results

  • Scan at 300 DPI or higher. Higher resolution gives the OCR engine more detail to work with.
  • Ensure good contrast. Dark text on a white background produces the best results.
  • Keep pages straight. Skewed or rotated pages reduce accuracy. Use the Rotate PDF tool to fix orientation first.
  • Avoid handwriting. OCR works best with printed text. Handwritten notes may not be recognized accurately.
