OCR PDF

Make a PDF searchable and copyable.

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.

What this tool does

Useful for

How your document is handled

OCR runs in your browser. The selected OCR language models may be downloaded when first used, but the document itself is not sent to an AmrrkPDF application server.

Limits and compatibility

Accuracy depends on scan quality, language, resolution, rotation, page complexity, and the chosen settings. Results should be reviewed before legal, financial, or archival use.

If the result is not what you expected

Use a clear 300-DPI source when possible, select the correct document language, deskew rotated pages, and test a short range before processing the whole file.
