OCR

You can perform OCR (Optical Character Recognition) on any document with PSPDFKit for Web Server-Backed.

To do so, open the document from PSPDFKit Server and apply the performOcr document operation with Instance.applyOperations:

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

This will detect all English text in the document and make it available for searching and manual text selection.

Other Languages

If your document is written in a language other than English, you can extract its text by modifying the language parameter. For example, to perform OCR in Spanish, run:

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