To crompress PDF, we'll use
17+
[Aspose.PDF Cloud PHP SDK](https://products.aspose.cloud/pdf/php/)
18+
This Cloud SDK assists PHP programmers in developing cloud-based PDF creator, annotator, editor, and converter apps using PHP programming language via Aspose.PDF REST API. Simply create an account at [Aspose for Cloud](https://dashboard.aspose.cloud/#/apps) and get your application information. Once you have the App SID & key, you are ready to give the Aspose.PDF Cloud PHP SDK. This method leverages the Aspose.PDF Cloud SDK for PHP to optimize PDF documents efficiently. By automating the upload, optimization, and download processes, it simplifies the workflow for developers. The use of various optimization options ensures that the resulting PDF is smaller in size without compromising quality.
