- 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.
