OCR Mode

Translate scanned PDFs into clean, searchable documents

OCR Mode reads scanned and image-heavy PDFs, keeps content such as text, images, and tables, then rebuilds a clean document. It may not preserve the original page layout, fonts, or font sizes.

Why use OCR Mode?

Read scanned pages before translating

OCR extracts text from page images so scanned books, copies, and image-only PDFs can be translated instead of skipped.

Clean translated pages

The output is rebuilt for readability instead of matching the original design, reducing overlay artifacts, overlap, and garbled text.

Works better on difficult PDFs

Use OCR Mode for textbooks, academic papers, tables, and image-heavy pages where preserving the content matters more than preserving the exact layout.

Bilingual or translation-only output

Choose a bilingual file for review or a translation-only PDF for reading, printing, and e-readers.

How It Works

1

Upload your PDF

Upload a scanned book, academic paper, or image-heavy PDF. Turn on the OCR Mode switch before translating.

2

OCR, then AI translation

We extract machine-readable text with OCR, translate it with AI, and keep the document structure as clean as possible.

3

Download a clean PDF

Get a rebuilt PDF with searchable text. Choose bilingual or translation-only output when available.
