How to Extract Text from a PDF (and Why Scans Need OCR)

Learn the difference between selectable PDF text and page images, how to copy text, and when optical character recognition is needed.

A PDF can contain actual text characters, page images, or both. If you can select a sentence in a PDF reader, the file likely has a text layer. If each page behaves like a photograph, it is probably a scan and text extraction alone cannot recognize the words.

Extract selectable PDF text

Open PDF to Text and choose the PDF. The current page uses PDF.js in the browser to read text items from the file, then lets you copy the result or download a TXT file. The source PDF is not edited.

Why the extracted text may look different

Text extraction returns reading-order text, not a visual replica of the page. Columns, tables, footnotes, and unusual font encodings can appear in a different order or lose spacing. Compare important passages with the original document rather than assuming the extracted text is exact.

Scanned PDFs require OCR

Optical character recognition (OCR) analyzes page images and guesses the characters shown in them. PDFPK’s PDF to Text page does not include OCR. If the result is blank or incomplete, use an OCR-capable application and proofread the recognized text—especially names, numbers, and punctuation.

You can use the PDF Reader to inspect a local file, or convert pages to PNG images when you need image files rather than searchable text.
