JPedal: Mastering PDF Assembly and Page Geometry

JPedal is continuing its evolution into a comprehensive Java PDF powerhouse. The December 2025 release introduces "heavy-lifting" capabilities for the PDF Merger and Manipulator, designed to give developers total control over document assembly, page normalisation, and layout precision.

Focus of this Release: Advanced Transformation & Tooling

Our goal is to streamline complex document workflows. This release focuses on making it easier to standardize disparate PDF sources and interact with document structures directly through the JPedal Viewer.

Key Features & Improvements

• Advanced PDF Merging: Normalise page dimensions and rotation across different files, add dividing pages, and insert custom footers automatically.
• Precision Page Control: The PDF Manipulator now allows you to scale pages to specific dimensions and crop content with ease.
• Automated Table of Contents: Generate a full Table of Contents instantly from existing document bookmarks.
• Metadata & View Control: Easily remove initial view settings and annotations to clean up or repurpose documents.
• In-Viewer Manipulation: A new Tools menu in the JPedal Viewer allows users to perform manipulation tasks without leaving the interface.

• Fixed UI bugs in text selection for continuous and continuous facing viewing modes.
• Improved the accuracy of some blend modes and premultiplied alpha handling.
