PDF OCR & Extraction — Free Online Tool
High-value PDF toolkit in-browser: Tesseract OCR for scans, fast embedded-text export, heuristic Excel & CSV, duplicate-page detection, smart clustering…
Frequently asked questions: When should I use OCR instead of “Extract text”? Extract text reads the PDF’s existing text layer—it is instant when present but empty for pure scans. OCR rasterizes each page and runs Tesseract; it is slower but works on image-only PDFs. How accurate is duplicate detection? Long pages use normalized exact text; scans compare perceptual hashes. Visually similar but different documents can occasionally cluster—always spot-check before deduping legal records.
