OCR PDF
Convert scanned PDF documents into editable text securely in your browser. No uploads. No server. 100% private.
What Is OCR PDF?
OCR PDF is a browser-based tool that uses Optical Character Recognition (OCR) to extract editable text from scanned PDF documents. Scanned PDFs are essentially images embedded in a PDF container. Our tool uses PDF.js to render each page as a high-resolution image and then passes it to Tesseract.js, a WebAssembly-based OCR engine, to recognize and extract the text.
Unlike cloud-based OCR services, everything happens locally inside your browser. Your PDF never leaves your device, making it suitable for confidential contracts, medical records, and financial documents.
The tool includes an AI Cleanup post-processing feature that automatically fixes broken line breaks, merged paragraphs, and duplicate spaces — improving readability without any server-side AI.
How It Works
- 1Upload PDF: Drag and drop your scanned PDF into the drop zone or click Browse Files.
- 2Configure Settings: Choose pages to process, OCR language, quality mode, and formatting options.
- 3Start OCR: Click Start OCR. PDF.js renders each page, which Tesseract.js processes locally for text recognition.
- 4Review & Download: Edit text, use Search & Replace, apply AI Cleanup, then download as TXT or Markdown.

Frequently Asked Questions
What is OCR?
OCR (Optical Character Recognition) reads text from images or scanned documents and converts it into machine-readable, editable text.
Can OCR read scanned PDFs?
Yes. Our tool renders each page using PDF.js, then passes the image to Tesseract.js for character recognition.
Is OCR private? Does my PDF get uploaded?
Your PDF never leaves your device. All processing happens locally in your browser. No data is transmitted anywhere.
What is the AI Cleanup feature?
AI Cleanup is a rule-based post-processing pass that fixes broken line breaks, merges wrapped paragraphs, removes duplicate spaces, and normalizes quotation marks — entirely client-side.
Can I OCR only specific pages?
Yes. You can process all pages, current page, odd pages, even pages, or a custom range like "1,3,5-8".
Is there a file size limit?
No artificial limits. The only constraint is your device memory and CPU. Very large PDFs may take several minutes.
Can I cancel OCR mid-process?
Yes. A Cancel button appears during OCR processing. Any text already extracted from completed pages is preserved.
Do I need an account?
No. The OCR PDF tool is 100% free with no registration, no account, no usage limits, and no watermarks.
