Acrobat OCR: How-to & Free Alternatives

Quick answer: The full Acrobat scan-and-OCR pipeline: scanner straight into a searchable PDF in one pass. Open 图片 OCR — everything runs locally in your browser, and files never leave your device.

Steps

1. Scan at 300 DPI, document mode, grayscale — Create → From Scanner inside Acrobat.
2. Enable "Make text searchable (OCR)" so recognition runs during import.
3. Verify with Ctrl+F on a known phrase; spot-check pages.
4. Re-scan problem pages after fixing contrast and skew — tuning settings rarely rescues a bad scan.

Important notes

• Scan parameters decide everything: 150 DPI scans are beyond repair by settings.
• Use the ADF for double-sided documents and clear stray blank pages afterwards.
• For archive digitization, fix a naming standard (date_id_page) before the first scan.

Common questions

Color or grayscale? Grayscale for text (smaller, steadier recognition); color only when stamps or signatures carry information.

Batch mode? Acrobat's Action Wizard handles multi-file batches — see the batch OCR guide.
