Possible disadvantages

• Privacy concerns with sensitive data
  Submitting sensitive or confidential data to any online encoding tool raises potential privacy and security concerns, as users cannot fully verify how their data is handled on the server side.
• Requires internet connection
  As a web-based tool, Base64Encode.dev cannot be used offline, which can be a limitation for users who need encoding capabilities in environments without internet access.
• Limited advanced features
  The tool focuses primarily on basic Base64 encoding and decoding, and may lack advanced features such as batch processing, file encoding for large files, or integration with other encoding schemes.
• No API for automation
  The tool may not offer a dedicated API endpoint for developers who want to integrate Base64 encoding/decoding into their automated workflows or CI/CD pipelines.
• Dependent on third-party availability
  Users relying on this tool are dependent on the website's uptime and availability. If the site experiences downtime or is discontinued, users lose access to the functionality entirely.
