What languages does OCR support?

Supports multiple languages including Chinese and English. You can select the primary language in the document to improve recognition accuracy.

How accurate is the recognition?

Accuracy depends on scan quality and text clarity. Clear printed documents typically achieve over 95% accuracy.

Will OCR change the document appearance?

No. OCR adds a transparent text layer over the original image. The document appearance remains unchanged, but text becomes selectable and searchable.

Can it process multi-page documents?

Yes. The tool processes multi-page PDFs page by page, performing OCR recognition on each page.

What is the processing speed?

Depends on document page count and complexity. Typically takes a few seconds per page.
