Ten, Commonly Asked Questions and Answers (5-10 Questions and Answers)
- Q1: Why can’t I open the software after installation?
A1: This is usually due to macOS security policies. Go to “System Preferences – Security & Privacy – General”, and click “Open Anyway”. If it still doesn’t work, try right-clicking on the software icon and selecting “Open”.
- Q2: What should I do if the activation code is invalid?
A2: Check for any extra spaces in the activation code. Some activation codes require offline activation. First, disconnect from Wi-Fi, input the activation code, and then activate once you’re back online.
- Q3: How can I fix scrambled text after OCR recognition?
A3: Ensure the resolution of the scanned document is above 300 DPI. If the font in the original document is special, consider converting it to a standard font before recognizing. You can also choose the “Chinese (Simplified)” language pack in OCR settings.

A4: Click “File – Export as – Word Document”. If the layout is messed up during conversion, try saving the PDF/A format first before converting.
- Q5: What should I do if the software runs slowly?
A5: First, close other applications that are using memory. In Nitro PDF Pro’s “Preferences – Performance”, set the “Rendering Quality” to “Standard”. If the document is too large, consider splitting it into smaller files.

Twelve, Tips and Practical Cases
Tips 1: Batch Signature Processing for Contracts
If you need to sign multiple contracts, you can use Nitro PDF Pro’s “Batch Signing” feature. First, create a template with signature fields. Then, use the “Combine Files” feature to merge multiple contracts. Finally, add signatures uniformly, significantly saving time.
Tips 2: Proofreading OCR-recognized Text
After OCR recognition, there may be recognition errors in the text. Enable the “Spelling Check” feature (in “Edit – Spelling Check”). Also, use “Find & Replace” to correct common errors, such as replacing “0” with “O”.
Practical Case: An In-House Law Firm’s Paperless Transformation
A medium-sized law firm adopted Nitro PDF Pro, reducing the time needed to organize past cases from 3 days to half a day. The process is as follows: Law assistant scans paper files → OCR recognition → Generates searchable PDF → Partners review online → Final version is encrypted and archived. The entire process is paperless, and the document security is ensured.
