📎 Attach Files to PDF Documents with Ease

Attach files to PDF documents [attach] [Featured]

Technical writers and content creators will love the new ability to attach files — such as spreadsheets, source code, reference documents, or additional media — directly to PDF outputs. Whether you need to include supplemental documentation for offline access or bundle supporting materials with your manuals, this new feature makes it incredibly easy. Simply mark your build assets as PDF attachments, and they’ll be embedded within the final PDF. It’s a game-changer for creating comprehensive, all-in-one documentation packages.

🖼️ A Smarter, Faster, More Powerful Image Editor

Working with images in HelpNDoc just became more versatile, reliable, and efficient.

The built-in image editor in HelpNDoc just got a serious upgrade. You can now import and display scalable vector graphics (SVG), giving you crisp, resolution-independent visuals for your image editing tasks. Ruler units are now customizable with a handy popup menu that lets you switch between pixels, imperial, or metric measurements. Beyond new features, we’ve also significantly enhanced performance: you’ll notice smoother interactions, faster loading times, and better reliability when working with a variety of image formats. Text wrapping within image layers has been improved for better paragraph alignment, undo/redo operations are more reliable, and several dialogs have been redesigned for a more consistent look and feel.

🛠️ Performance Fixes and Improvements Across the Board

We’ve tackled bugs, optimized performance, and fine-tuned the user experience throughout.
