UPDF for Windows 2.5.6

This update adds the ability to rotate images and text within PDFs to any desired angle, enabling more flexible content orientation adjustments based on document layout and usage needs.

Additionally, the update supports document separation during batch duplex printing, detection settings for PDF/A documents and digital signatures, and batch deletion of multiple items from annotation and form field lists.

Other improvements include manual adjustment of crop areas when removing white margins, and enhanced tone adjustment and proofreading features in AI-powered editing, making PDF workflows on Windows more comfortable and efficient.

More Flexible and Smooth PDF Editing, Printing, and Management

In professional settings involving business documents, contracts, and application forms, users often require more than just editing—tasks such as print configuration, annotation management, and verification of document standards and digital signatures are common.

UPDF for Windows 2.5.6 enhances content editing flexibility while strengthening features for batch printing, annotation and form management, and document detection settings. This enables more efficient use across a broader range of applications, from daily PDF tasks to enterprise document management.

Key Updates in UPDF for Windows 2.5.6

1. Rotate Images and Text at Any Angle

Users can now freely rotate images and text within PDFs to any angle based on their needs.

Beyond simple portrait and landscape switching, fine-grained angle adjustments are now possible, allowing greater editing flexibility when aligning visuals or creating design-oriented documents.

2. Support for Document Separation in Batch Duplex Printing

When printing multiple PDFs together in duplex mode, users can now separate print jobs at document boundaries.

This makes it easier to manage individual documents when printing different PDFs consecutively, allowing output of organized materials and handouts.

3. Added Detection Setting for PDF/A Documents

Users can now enable or disable detection of PDF/A documents—designed for long-term archiving—via settings.

This allows more flexible configuration of the editing environment depending on use cases and workflow requirements involving PDF/A documents.

4. Added Detection Setting for Digital Signatures

Detection of digital signatures within PDFs can now be toggled on or off.

This enables users to adjust detection settings based on specific needs, such as handling signed documents or prioritizing standard PDF editing.

5. Batch Deletion of Multiple Items from Annotation and Form Lists

Users can now select and delete multiple items at once from annotation and form field lists.

This reduces the effort required to clean up documents with numerous comments, highlights, or form fields, streamlining document organization.

6. Manual Adjustment of Crop Area When Removing White Margins

The white margin removal tool now allows manual adjustment of the crop area.

Users can fine-tune the automatically detected area to better fit document content, ensuring essential parts are preserved while more accurately removing unwanted whitespace.

7. Improved AI Editing: Tone Adjustment and Proofreading

The AI-powered text editing features, including tone adjustment and proofreading, have been enhanced.

These improvements streamline rewriting text for different purposes or audiences and refining content to be more natural and readable. The features are useful for creating emails, reports, proposals, and other documents.

8. Bug Fixes and Stability Improvements

Additional fixes have been implemented for issues reported by users.

Overall application stability has been improved, enhancing the comfort and performance of viewing, editing, annotating, form handling, printing, and AI editing tasks on Windows.
