How to Tell If a PDF Is Scanned

A scanned PDF usually behaves like a picture of a page. A searchable PDF lets you select and copy words.

Selectable PDF text compared with scanned image-only PDF text
Try selecting a word: searchable PDFs behave differently from image-only scans.

Quick answer

What you need to know first

Try selecting a word. If the page selects as one image or nothing selectable appears, the PDF is likely scanned or image-only.

  1. 1Open the PDF in a viewer.
  2. 2Try selecting one word.
  3. 3Search for a word you can see on the page.
  4. 4Use PDF to Text only if text is selectable.

Simple tests that work

The fastest test is text selection. Search is another clue: if the viewer cannot find a word that is visibly on the page, the PDF may not contain a text layer.

Some PDFs contain both a scanned image and OCR text. Those are searchable PDFs even though the visual page still looks like a scan.

Why it matters

Text extraction, copy workflows and search depend on selectable text. Image-only scans need OCR before they behave like searchable documents.

FAQ

Common questions

Can a scanned PDF be searchable?

Yes, if OCR has added a text layer behind the scanned page image.

Does file size reveal whether a PDF is scanned?

Not reliably. Scans are often larger, but file size alone is not proof.
