### "Unsupported file type"
### "No content selected" (Clip Selection)
**Cause**: No text or content is selected on the page.
**Solution**:
- Select text or content on the page before clicking "Clip Selection"
- Use "Clip Full Page" to capture the entire page without selection
### "Failed to convert to PDF"
**Cause**: The browser's PDF conversion API failed.
**Solutions**:
- Ensure you're using a modern version of Chrome/Edge/Firefox
- Check browser console for detailed error messages
- Try clipping a simpler page to test
- Ensure the page has finished loading
### "Unsupported file type" (URL Mode)
**Cause**: The URL doesn't point to a supported file type.
**Solution**:
- Verify the URL ends with a supported file extension
- Check that the Content-Type header is set correctly by the server
- Use "Clip Page" mode instead to capture web content
### "File too large"
**Cause**: The file exceeds the maximum upload size configured in DocuElevate.
**Cause**: The file/PDF exceeds the maximum upload size configured in DocuElevate.
**Solutions**:
- Check your DocuElevate `MAX_UPLOAD_SIZE` configuration
- Try a smaller file
