The Top 5 PDF Signers for Mac

Here, we shine a spotlight on five of the best in the business, highlighting what makes them special.

UPDF for Mac

UPDF is a budget-friendly and intuitive PDF tool that allows users not only to annotate, edit, convert, and sign their PDFs but also offers a comprehensive suite of PDF editing capabilities.

Preview stands as the default PDF and image viewer on Mac, bringing a plethora of functionalities for both viewing and editing PDFs. Delve into its capabilities, and you'll find options for text and shape addition, content redaction, freehand sketches, sticky note inclusions, and signature captures through trackpad, camera, or even iPhone. With macOS Monterey, Preview further ups the ante, introducing permissions for PDF owners to regulate printing, content copying, and page manipulations.

However, Preview isn't without its limitations. It misses out on advanced provisions like text editing within PDFs, OCR capabilities, and has restricted in-built sharing features. Moreover, its exclusivity to the Mac environment might pose a challenge for diverse users. For those seeking a richer PDF editing experience, options like UPDF present a wider arsenal of tools tailored for in-depth PDF management.

This software is lauded for its pristine and user-centric interface, ensuring a seamless navigation experience even for those new to the world of PDF editing. From tweaking text, adjusting images, and modifying links to merging, converting, and signing documents, PDF Expert has got you covered.

While its capabilities are vast, its exclusivity to macOS, iPadOS, and iOS might be a drawback for some. And while its comprehensive features are a boon, they might require a slightly longer adjustment period for some users due to the software's rich functionalities.
