Convert scanned PDFs to searchable PDFs using JavaScript

You can convert scanned documents to searchable PDFs with Nutrient Web SDK.

Converting scanned documents to a searchable PDF is available when using Web SDK with Document Engine. For more information, refer to the operational mode guide.

To perform the conversion, first open the document from Document Engine, and then apply the performOcr document operation:

await instance.applyOperations([
  { type: "performOcr", language: "english", pageIndexes: "all" }
]);

This will detect all English text in the document and make it searchable.

ℹ️ Note: This feature requires the OCR component to be enabled in your license.

Other languages

If your scanned document is written in a language other than English, you can make it searchable by modifying the language parameter. For example, to convert the document to Spanish, run:

await instance.applyOperations([
  { type: "performOcr", language: "spanish", pageIndexes: "all" }
]);
