Known limits

- Encrypted or damaged PDFs may not open unless the specific tool supports that workflow.
Troubleshooting
- If the PDF does not open or processing stops, try a smaller file or close extra tabs to free browser memory.
- If the file is password-protected or damaged, first confirm it opens in a regular PDF viewer.
