Extract Text from Scanned PDFs — Free OCR

OCR (Optical Character Recognition) converts images of text into machine-readable text. This is essential for scanned documents, photos of documents, and image-based PDFs.

PDF Tools Pro uses Tesseract OCR engine to extract text. Upload your scanned PDF or image, and our server processes it. The extracted text is returned as plain text or can be saved as a searchable PDF.

OCR quality depends on the original scan quality. 300 DPI scans with clear text produce the best results. Handwritten text and low-contrast documents may have lower accuracy.
