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 the Web SDK with Document Engine in server-backed operational mode.

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" }
]);
