What it does

BulkPro PDF OCR recognizes the text in scanned or non-text PDFs and adds a real text layer behind the document. The page looks identical but becomes searchable with Ctrl+F and copyable. Powered by the Tesseract OCR engine, it supports Turkish, English, German, French and mixed languages, deskews tilted scans, cleans noise, and processes dozens of documents at once.

How to use it

  1. 1Drag the scanned PDFs onto the list.
  2. 2Pick the Primary Language (Turkish, English, German, French or mixed).
  3. 3Leave Auto-deskew and Denoise on (recommended for scans).
  4. 4Click Run. A same-looking but searchable PDF is produced.

Use cases

Add 50 scanned contracts, language Turkish, default settings; all become searchable with Ctrl+F.

Mixed-language academic paper

Pick 'Turkish + English'; accuracy improves on quoted, bilingual text.

Fix a broken text layer

If search returns wrong results, turn on 'Force OCR' to re-recognize from scratch.
