Tips for Best Results

  • Use text-based PDFs: Documents created digitally work better than scans.
  • Leave space for signatures: Make sure there's room at the bottom or designated areas.
  • Check orientation: Rotate pages to the correct orientation before uploading.
  • Remove password protection: Save an unprotected copy before uploading.

🔧 Troubleshooting

Upload fails

Check file size (max 50 MB) and ensure it's a valid PDF.

Pages look blurry

Upload a higher resolution PDF or the original digital file.

Text is not selectable

This is normal for scanned documents. Signatures still work.
