Convert a Scanned PDF to Searchable Text

Scanned PDFs are essentially images — you can see the text but can't select, search, or copy it. OCR (Optical Character Recognition) reads the text from these images and makes it usable. OneClickPDF's OCR tool supports 16 languages and can output searchable PDFs, plain text files, or even CSV from detected tables.

The Problem

You have a scanned document — a paper form, a printed letter, a receipt — saved as a PDF. The text is trapped in images and you need to extract it for editing, searching, or data entry.

How It Works

  1. Open the OCR tool

    Go to OneClickPDF's OCR tool.

  2. Upload the scanned PDF

    Drop the scanned PDF or image file. The tool accepts both PDF and direct image uploads.

  3. Configure OCR settings

    Select the document language (16 languages available). Optionally adjust image preprocessing — grayscale, contrast enhancement, or thresholding can improve recognition accuracy on poor-quality scans.

  4. Run OCR and choose output

    The tool processes each page and extracts text with word-level confidence scoring. Choose your output: searchable PDF (invisible text layer over the original images), plain text file, or text-only PDF. Tables are detected automatically with CSV export available.

Frequently Asked Questions

What languages are supported?
16 languages: English, French, German, Spanish, Italian, Portuguese, Dutch, Polish, Russian, Japanese, Chinese (Simplified and Traditional), Korean, Arabic, Hindi, and Turkish.
Can I OCR just part of a page?
Yes. The region selection feature lets you draw boxes around specific areas — useful for extracting text from a particular section while ignoring headers, footers, or images.
What's a searchable PDF?
A searchable PDF looks identical to the original scan but has an invisible text layer. You can search for words, select text, and copy content — while the visual appearance stays exactly the same.
Can it extract data from tables?
Yes. The OCR engine includes table detection. When tables are found, you can export the data as CSV for use in spreadsheets.

From paper-trapped text to fully searchable, copy-able content — OCR transforms scanned documents into usable data. With 16 languages and table detection, OneClickPDF's OCR handles documents from around the world.
