Complete Guide: PDF OCR & Text Recognition
Make scanned PDFs searchable and editable — from basic OCR to advanced table extraction and multilingual recognition.
What OCR changes in a PDF
OCR adds a searchable text layer behind scanned pages so you can copy, search, and convert the document instead of treating each page as a flat image.
Common OCR-first workflows
Many teams OCR a scan before Word conversion, Excel extraction, merge review, or archival search. OCR is often the unlock step, not the final destination.
How to judge OCR quality quickly
Search for a known phrase, copy a table cell, and spot-check mixed-language lines. If those three checks pass, downstream conversion is usually worth attempting.
When OCR should not be the first move
If the PDF already has a clean text layer and the real problem is editing one section or trimming a long packet, split first or go straight to Word. OCR is recovery, not a universal opening move.
