Knowing the functions is not enough. True masters know how to combine and apply them. Below, I share a few practical tips to help you use PDF Expert 2 more smoothly.

Tips 1: Quickly Sign Contracts

Scenario: You receive an electronic contract and need to quickly sign and return it. Open the PDF, click the “Sign” icon in the toolbar, choose “Create Signature”. Use the touchpad or camera to enter your signature, save it, and drag it to the signature area. The whole process takes less than 30 seconds.

Tips 2: Merge Multiple Reports

Scenario: You need to combine three independent weekly reports into a monthly report. Open PDF Expert 2, click “File” > “Merge”, drag the three files in sequence into the window, and click “Merge”. The merged document will automatically retain the original page numbers and bookmarks.

Tips 3: Efficiently Comment on Papers

Scenario: Your mentor needs to review the student’s paper. Use the highlighting tool to mark key arguments, and use the sticky note feature to write revision suggestions. Utilize the “Annotation List” panel to quickly browse all annotations, avoiding omissions. After completing the annotations, directly export the PDF version with annotations.

Tips 4: Extract Key Pages

Scenario: From a 200-page e-book, you only need the content from page 50 to 60. In thumbnail view, hold the Command key to select these pages, right-click to choose “Extract”. The extracted pages will form a new PDF file, making it convenient for you to carry around.

Tips 5: Batch Adjust Text Formats

Scenario: You find that all the titles in the PDF have inconsistent fonts. Use the “Edit” mode, select one title, right-click to choose “Select All Matching Text”. Then, uniformly modify the font, size, and color. This trick can save you a lot of time manually adjusting.
