Six, Common Issues FAQ

Based on user feedback, I’ve compiled 10 frequently asked questions to help you quickly resolve your usage issues.

1. Why does it prompt “Damaged” after installation?

This is usually due to strict system security policies. Ensure that Gatekeeper is disabled, or allow the software to run in “Security & Privacy” under “General” settings. If the issue persists, try re-downloading the installation package.

The activation code may have a usage limit. Check if you have exceeded the activation limit. Consider disconnecting from the network and activating again, or contact us for a new activation code.

The OCR recognition accuracy depends on the quality of the original image. Use scanned images with a resolution of 300 DPI or higher, and ensure the text is clear. The software supports 90+ languages, so make sure to select the correct language options in settings.

4. How can I batch convert PDF files?

On the main interface of the software, choose “Tools” -> “Batch Conversion”. You can drag multiple PDF files into the interface, select the output format (such as Word or Excel), and then click “Start” to begin the conversion process.

Nine, Tips and Real-World Cases

Knowing the features isn’t enough; mastering their use in real-world scenarios is crucial. Below, I share a few verified tips and cases.

Tips 1: Quickly Summarize Papers with AI Assistant

Academic researchers often need to read numerous PDF papers. After opening a 20-page document, click the AI Assistant icon in the upper right corner, then choose “Smart Summarize”. In a few seconds, the software generates a 300-word summary, helping you quickly grasp the main points. This feature leverages a deep thinking analysis model, significantly outperforming manual reading.

Tips 2: Batch Process Contract Documents

If you have 50 contracts needing watermarks and headers added, don’t open them one by one. In the “Tools” menu, select “Batch Process”. Add all files first, then set the watermark content and header format uniformly. Click “Apply”, and the software will automatically process and save them to the designated folder. The entire process takes less than 5 minutes.

Tips 3: Use OCR to Convert Scanned Documents into Editable Formats

Company-issued scanned contracts are often not editable. In PDF Reader Pro, click “OCR” -> “Recognize Text”. The software automatically analyzes the text in the images, generating a searchable and editable PDF layer. Subsequently, you can edit text and copy content as if working with a regular document. The recognition accuracy is above 95%, requiring minimal secondary review.

Xiao Zhang, a graduate student at a university, faced piles of references and his professor’s feedback during graduation season. He first used the software’s split-screen comparison feature to display his initial draft and feedback side-by-side, cross-referencing each point. Next, he used the annotation tool to add sticky notes in the required modification areas and highlight important points. Finally, he used the AI Assistant’s “Rewrite” feature to refine a few sentences that were unclear. The entire process was seamless, and he successfully passed the defense.
