Aspose.PDF Cloud PHP SDK enables developers to build cloud‑based PDF generator, editor, and converter applications capable of accessing and processing PDF files stored on cloud storage. The SDK is released under an MIT license and is built on top of the Aspose.PDF REST API. With it, developers can create entirely new PDF documents, or convert existing documents—including spreadsheets, presentations, images, ebooks, HTML, and PS files—into PDF. The PHP SDK allows cloud applications to merge multiple PDFs, split documents, append pages, encrypt or decrypt files, apply watermarks, manage bookmarks, insert annotations, and digitally sign PDF documents. Beyond manipulation features, the SDK can export structured data from PDFs, insert OCR layers, add headers and footers, and download attachments. It offers powerful PDF conversion capabilities, broad annotation support, extraction features, and optimization tools, enabling rich PDF workflows entirely through PHP script execution without installing Adobe Acrobat or any third‑party tools.
