# Free PDF OCR Tool (Extract Text from Scanned PDF)

Extract text from scanned PDF pages locally in your browser. Multi-page document OCR with high-accuracy Tesseract WASM.

## What is PDF OCR Tool (Extract Text from Scanned PDF)?

PDF OCR turns scanned documents and image-only PDFs into searchable, copyable text. Each page is rendered in your browser with pdf.js and read by the Tesseract OCR engine, so confidential contracts, invoices and records never leave your device. Choose the document language — English, Spanish, French, German, Italian or Portuguese — process all pages or a custom page range, then view the text page by page or download everything as a .txt file. Clear, high-resolution scans give the best accuracy.

## How to use PDF OCR Tool (Extract Text from Scanned PDF)

1. **Upload the PDF** — Choose a scanned or image-based PDF.
2. **Choose language and pages** — Select the document language and all pages or a page range.
3. **Run OCR and download** — Start recognition, review the text for each page, and download it as .txt.

## Frequently asked questions

### How accurate is the OCR?

Clean printed text at 300 DPI is usually recognised with over 95% accuracy. Handwriting, low-resolution photos and skewed scans reduce accuracy.

### Why does the first run take longer?

The OCR engine and language data (about 2–3 MB per language) download once and are then cached by your browser.

### Does it work on PDFs that already contain text?

Yes, but for PDFs with a real text layer, copying the text directly or using a PDF-to-text tool is faster and exact.
