What’s the difference between OCR Mode and Native PDF Mode? Which should I choose?

Core Issue Diagnosis

Not all PDFs are the same: PDFs generated from scans require specialized processing.

Root Cause Analysis

Native PDF Mode (Recommended)

If you can select and copy text in your PDF, please use this mode. This mode achieves complete layout restoration by parsing vector coordinates, and also processes files more quickly.

Enhanced OCR Mode

Designed for photos taken by mobile devices and older scanned documents. DL.Translator will activate the visual engine to recognize text shapes. Although its fidelity is slightly lower than native mode, it can address the problem of 'unable to translate images.'

Final Solution Summary

The system will typically detect and recommend the optimal mode automatically, so users only need to review the final preview result.
