OCR PDF

使 PDF 可搜尋且可複製。

How it works:

  • Extract Text: Uses Tesseract OCR to recognize text from scanned images or PDFs.
  • Searchable Output: Creates a new PDF with an invisible text layer, making your document fully searchable while preserving the original appearance.
  • Character Filtering: Use whitelists to filter out unwanted characters and improve accuracy for specific document types (invoices, forms, etc.).
  • Multi-language Support: Select multiple languages for documents containing mixed language content.
