How it works

OCR your PDF in three steps

  1. 1

    Upload your scanned PDF

    Drag and drop your PDF onto the tool or click to browse. The file loads directly in your browser — never sent to any server.

  2. 2

    Pages are rendered and analysed

    Each page is rendered to a high-resolution image. tesseract.js then reads the image and extracts the text using Optical Character Recognition. A progress bar shows per-page status.

  3. 3

    Review and download the text

    The extracted text is shown in a scrollable preview — one section per page. Click 'Download .txt file' to save it.

FAQ

Common questions

What languages does the OCR support?
The tool is configured for English by default. tesseract.js supports 100+ languages — additional language support is planned for a future update.
How accurate is the OCR?
Accuracy depends on scan quality. Clear black-and-white scans at 200 DPI or higher typically yield 90–99% accuracy. Low-resolution, skewed, or handwritten documents will have lower accuracy.
How long does OCR take?
About 5–15 seconds per page depending on your device's CPU speed. A 10-page document typically completes in 1–2 minutes.
What is the difference between OCR PDF and PDF to Text?
PDF to Text extracts the built-in digital text from text-based PDFs (no OCR needed). OCR PDF converts page images to text — it works on scanned or image-only documents where there is no embedded text layer.
