Why Processing Fails
File is encrypted or password-protected
Unexpected file structure
PDF contains corrupted layers
OCR cannot read scanned document
Very low-quality image input
Fix Steps
If PDF is password-locked → unlock using Password Remove tool
If image is unclear → upload higher quality version
Try converting to another format first
Split the document and process pages individually
Re-upload as a flattened PDF (print to PDF)
If Still Not Working
Send support: file, tool used, timestamp.
