• Potential File Size Limitations
  Free online compression tools typically impose upload file size limits, which can be restrictive for users needing to compress larger files.

  Uploading sensitive or confidential files to any online compression service poses potential privacy and security risks, as files are processed on external servers.

  Third-party GPT wrapper websites often depend on underlying API access that can be unstable, rate-limited, or discontinued without notice, affecting consistent availability.

  Using an unofficial third-party service to process conversations raises questions about how user data and conversation history are stored, used, or shared.

  It may be unclear which underlying AI model version is being used, how up-to-date it is, or what modifications have been made to the base model's behavior.
• Potential Hidden Costs or Ads
  Free-to-use AI wrapper sites often monetize through ads, premium upsells, or data collection, which may not be clearly disclosed to users upfront.
• Lack of Official Support
  Unlike official AI platforms, unofficial wrapper sites may lack dedicated customer support, regular updates, or accountability if issues arise.
