Choose an Evaluation License

LEADTOOLS requires a license file, even for evaluation. You can either download and install the full evaluation, or get a limited license paired with your NuGet package.

The recommended way to receive a license file is to download the Full Evaluation, which includes all LEADTOOLS Document, Medical, Imaging, and Vector technologies for all development and target platforms. The license file included with the Full Evaluation Download is a 60-day, fully functional license with no watermarking.

Alternatively, if you only want to download and evaluate our NuGet packages, you can receive a 30-day, limited license file that will randomly watermark your images and documents.
