Aspose PDF License

License

• The Rust source code is licensed under the MIT License.
• The shared library (AsposePDFforRust_windows_amd64.dll, libAsposePDFforRust_linux_amd64.so, libAsposePDFforRust_darwin_amd64.dylib, libAsposePDFforRust_darwin_arm64.dylib) is proprietary and requires a commercial license. To use the full functionality, you must obtain a license.

Evaluation version

You can use Aspose.PDF for Rust via C++ free of cost for evaluation.The evaluation version provides almost all functionality of the product with certain limitations. The same evaluation version becomes licensed when you purchase a license and add a couple of lines of code to apply the license.

• If you want to test Aspose.PDF for Rust without the evaluation version limitations, you can also request a 30-day Temporary License. Please refer to How to get a Temporary License??

Limitation of an evaluation version

We want our customers to test our components thoroughly before buying so the evaluation version allows you to use it as you would normally.

• Documents created with an evaluation watermark. The evaluation version of Aspose.PDF for Rust provides full product functionality, but all pages in the generated files are watermarked with the text “Evaluation Only. Created with Aspose.PDF. Copyright 2002-2025 Aspose Pty Ltd.” at the top.
• Limit the number of pages that can be processed. In the evaluation version, you can only process the first four pages of a document.

Use in production

A commercial license key is required in a production environment. Please contact us to purchase a commercial license.
