Inputs stay in this tab and are not uploaded or saved automatically. Optional aggregate usage counts and coarse processing diagnostics are sent only after consent, without input content or filenames. Clearing or closing loses inputs; save needed outputs first.
Resource limits
2 to 32 distinct percentage keyframes, including 0 and 100. Translation ±500 px, rotation ±1080°, scale 0 to 5, opacity 0 to 1, duration 0.1 to 60 seconds, 1 to 20 iterations. Playback is manual and respects reduced motion. This is a local, bounded preview, not a universal guarantee for every browser or layout. Inputs are never executed. Download HTML and CSS together. Watchdog: 8 seconds.
How to use
- Configure the example
Edit the percentage, translation, rotation, scale and opacity for each state. Set the duration, easing and iterations. Generate, then play or pause the local preview yourself; the same sequence is exported.
