• Support for Multiple Formats

Possible disadvantages

  The ImageOptim API is a paid service, which may not be cost-effective for smaller projects or those with limited budgets.
• Dependency on External Service
  Using an external API means that your service is dependent on the uptime and reliability of ImageOptim, which could be a risk if their service experiences downtime.
• Limited Control Over Process
  While the API offers some customization, users might have limited control compared to local optimization tools where they can deeply tweak optimizations and algorithms.
