Frequently asked questions
What are the default values?
The defaults (0.25, 0.1, 0.25, 1) match CSS's built-in ease timing function.
Can Y values go above 1 or below 0?
Yes — that creates an overshoot or bounce effect in the animation.
Is this tool free to use?
Yes, completely free on FreeToolsNets, with no sign-up and no limits.
Is my data sent to a server?
