Set the license key by using the Sdk.Initialize method before calling the library.

note

The PDF Toolbox SDK and the Pdftools SDK differ in how they provide free or trial license keys (also called evaluation license keys in Pdftools).

  • PDF Toolbox SDK: Contact the Pdftools sales team through the Contact page to get an evaluation or full license key for the PDF Toolbox SDK. The evaluation license key is necessary to try the PDF Toolbox SDK.
  • Pdftools SDK: You can try the Pdftools SDK without a license key with watermarked output files. To remove the watermark from the output files, contact the Pdftools sales team through the Contact page to get a full license. No evaluation license key is necessary to try the Pdftools SDK.
