Best Practices & Pro Tips for Best Results
To ensure optimal results and avoid common issues when using Sign PDF Online (Free e-Signature), keep these practical recommendations in mind:
- Check Document Security: Ensure your PDF is not encrypted or write-protected with a master password before starting.
- Retain Originals: Keep an unmodified copy of your original file so you can experiment with different compression or extraction settings.
- Verify Text Layers: For scanned documents, remember that purely graphical scans lack underlying selectable text unless run through OCR.
Troubleshooting Common Issues
Missing text layers: Scanned pages consist solely of bitmap pictures without underlying text streams. Extracting text from pure image scans requires an OCR layer. Check that your PDF contains native selectable text.
