🔧 Troubleshooting

Extension Won't Load

• Make sure Developer Mode is enabled
• Check that all files are in the correct folder structure
• Refresh the extensions page

Conversion Fails

• Check that the input file is not corrupted
• Try a different output format
• Some exotic formats may not be supported
• Ensure enough system memory is available

Slow Performance

• Large files take longer to process
• Close other Chrome tabs to free up memory
• Try using a lower quality setting
• Some format combinations require more processing

Icons Not Showing

• Create PNG versions of the SVG icons
• Make sure they're named correctly (icon16.png, icon48.png, icon128.png)
• Reload the extension after adding icons
