Explanation on the frequency of use

VIP users and regular users are counted based on the number of uses per individual user. Anonymous users are counted based on their IP usage, meaning that when multiple unregistered users use the same public IP to access the tool, the usage count will be shared.
The above usage times, unless otherwise specified, are all hourly usage times.
VIP users will share usage count when using multiple tools. For example, the VIP usage of online image compression tools is 120 times/hour, and the VIP usage of online HMAC calculation tools is 720 times/hour. When a user uses online image compression 60 times within an hour, they can only use the online HMAC calculation tool 360 more times. If multiple API functions are used in a tool, each with a limit on the number of times they can be used, they will also share the number of times they can be used.
