Common Issues and How to Resolve Them

Even with the best tools and techniques, you might run into some issues when comparing PDFs. Here are a few common problems and how to resolve them:

• False Positives: Sometimes, the comparison tool might flag changes that aren't actually changes. This can happen if there are slight differences in formatting or if the tool is overly sensitive. To resolve this, try adjusting the settings or manually reviewing the flagged changes.
• Slow Performance: If the PDFs are very large or complex, the comparison process might take a long time. To speed things up, try splitting the PDFs into smaller sections or using a more powerful computer.
• Incompatible Files: Some comparison tools might not be compatible with certain types of PDFs. If you're having trouble, try converting the PDFs to a different format or using a different tool.
