How to Make a Scanned PDF Searchable with OCR

A scanned PDF is just a picture of text — you cannot select, copy or search it. OCR (Optical Character Recognition) reads the image and adds a real text layer, turning a scan into a searchable, selectable document. Here is how to OCR a PDF for free.

Step by step

  1. Open the OCR PDF (Searchable) tool.
  2. Upload your scanned PDF.
  3. Wait while the server recognises the text (this can take up to a minute).
  4. Download a searchable PDF you can copy from and search.

Tips

After OCR you can press Ctrl+F to find words inside the document, select and copy text, and even convert it to Word more accurately. It works best on clear scans; faint or handwritten pages may give mixed results. Files are deleted after processing.

Frequently asked questions

What does OCR do exactly?
It detects the text in a scanned image and adds an invisible, searchable text layer over it.

Does the page still look the same?
Yes — the appearance is unchanged; you just gain selectable, searchable text.
