Aspose.PDF Cloud Java SDK is built on top of the Aspose.PDF REST API and enables Java developers to seamlessly integrate cloud‑based PDF creation, editing, conversion, encryption, and processing functionality into their applications. Offered under the MIT license, the SDK supports generating PDF documents from scratch, importing various file formats into PDF for further processing, and exporting PDFs to numerous document, image, and markup formats. Applications using this SDK can manipulate individual PDF elements—such as text, annotations, watermarks, bookmarks, signatures, stamps, form fields, images, hyperlinks, and attachments—while also supporting key workflows like splitting, merging, signing, and securing PDFs stored in cloud environments. The SDK is platform‑independent and requires no local installation of Adobe Acrobat or other third‑party tools, making it suitable for modern cloud-native Java applications.

Features

PDF Creation & Conversion

• Create new PDF documents from scratch.
• Convert EPUB, LaTeX, HTML, PS, XSLFO, XPS, SVG, DOCX, PCL, XML, MD, and more to PDF.
• Convert PDF to DOC, DOCX, BMP, GIF, JPEG, PNG, TIFF, PPTX, XLS, XLSX, MOBIXML, EPUB, HTML, SVG, XPS, XML, PDFA, and other formats.
• Convert PDFs with XFA forms into AcroForm PDFs.
• Choose Word‑conversion mode:
  • Textbox mode: preserves the original layout.
  • Flow mode: optimizes for editability. PDF Manipulation
• Split large PDFs or merge multiple PDFs.
• Append documents to an existing PDF.
• Add document text or image headers/footers.
• Add, read, update, or delete text stamps and image stamps.
• Replace single or multiple text instances in an entire document or specific pages.
• Add, read, delete, or update tables; remove all tables from a page or entire PDF. Annotations & Document Elements Supports a full range of annotation types, including:
• Text, free text, line, circle, polygon, polyline, square
• Highlight, underline, squiggle, strikeout
• Caret, ink, link, popup, file attachment
• Sound, movie, screen, widget
• Watermark, redaction, rubber stamp, printer mark
• TrapNet, rich media annotations
• Annotation flags and states include: visibility, print restrictions, magnification limits, rotation restrictions, read-only mode, and states such as marked, unmarked, accepted, rejected, cancelled, completed. Security & Protection
• Encrypt or decrypt document content.
• Change PDF passwords.
• Set document access privileges, including printing, degraded printing, content modification, copying, form filling, and more. Extraction & Optimization
• Extract PDF images (GIF, JPEG, PNG, TIFF) to a folder.
• Extract annotations including file attachments, sound, screen, and stamp annotations.
• Optimize PDF documents:
  • Reuse page content
  • Control image compression
  • Link duplicate resource streams
  • Remove unused objects and streams
  • Avoid embedding fonts to reduce size
