Overview & Quick Answer

What is OCR PDF?

Run OCR on scanned PDF documents to extract editable text online for free. Convert scanned images into searchable PDF text with complete privacy.

Scanned documents and photocopies are essentially flat images wrapped in a PDF container, making it impossible to search for keywords or copy text. iLuvePDF runs an advanced Optical Character Recognition (OCR) neural network directly in your browser using Tesseract.js compiled to WebAssembly. The engine detects letterforms, computes bounding boxes, and overlays an exact invisible text layer over the image.
