Claude Limitations for OCR
- No scanned PDF support: Claude cannot open or process scanned PDFs. You must convert them to images first.
- Poor RTL support: Claude has limited accuracy for Arabic, Urdu, Farsi, and Hebrew — it does not handle right-to-left text properly for extraction.
- No searchable PDF output: Claude can only output plain text, not dual-layer searchable PDFs.
- Single-image only: Claude processes one image at a time, making bulk OCR impractical.
The FastOCR Advantage
- Native PDF processing: Upload scanned PDFs up to 1GB directly — no conversion needed.
- RTL language excellence: Dedicated models for Arabic, Urdu, Farsi with proper ligature handling.
- Searchable PDFs: Creates dual-layer PDFs with invisible text overlay for full-text search.
