What is PDF to OCR
PDF to OCR (Optical Character Recognition) is a cutting-edge web-based technology that converts scanned PDF documents, images, and screenshots into editable, searchable text without requiring any server uploads. Our free PDF to OCR converter uses state-of-the-art WebAssembly (WASM) processing entirely within your browser, ensuring 100% data privacy while delivering industry-leading accuracy.
Unlike traditional OCR solutions that send your sensitive documents to remote servers, our browser-native PDF to OCR tool processes everything locally using Tesseract.js and PDF.js. This revolutionary approach eliminates security risks, removes file size limitations, and provides instant results without interrupting your workflow.

Is PDF TO OCR really private?
Yes. Unlike i2OCR, PDF to OCR performs all extraction on your machine. The OCR engine loads directly into your browser's temporary memory via WebAssembly — no file data is ever uploaded. Disconnect your internet after the page loads and it still works.
How does it compare to i2OCR?
i2OCR limits uploads to 10 MB, one page at a time, and serves intrusive ads. PDF to OCR renders locally via PDF.js, extracts multi-page PDFs with no limits, and has zero advertisements.
What file formats are supported?
PDF, PNG, JPEG, and WEBP. Copy to clipboard, download as .txt, or export as .doc with table layouts preserved.
Can I run this as an API?
Yes. Built on open-source WASM libraries, you can integrate the engine into any pipeline. See the Developer API Hub for Node.js, Python, and CLI examples.
