What languages does PDF OCR support?

Our OCR tool supports multiple languages including English, Chinese (Simplified & Traditional), and more. Select the primary document language before processing for best accuracy.

How accurate is the PDF text recognition?

Accuracy depends on scan quality and text clarity. Clear, high-resolution scans of printed text typically achieve 95%+ accuracy. Handwritten text and low-resolution scans may have lower accuracy.

Will OCR change how my PDF looks?

No. OCR adds an invisible, transparent text layer over the original images. Your document looks exactly the same, but text becomes searchable, selectable, and copyable.

Is OCR processing done locally in my browser?

Yes. All OCR processing happens 100% in your browser using local computing power. Your scanned documents are never uploaded to any server.

How long does PDF OCR take?

Processing time depends on page count and document complexity. Typically, each page takes a few seconds. Large multi-page documents may take longer.
