Quick start

How to generate CSS keyframes

Create a reusable keyframes block and animation shorthand.

  1. Step 1
    Tune motion

    Set duration, delay, easing, rotation and scale values.

  2. Step 2
    Preview animation

    Verify the visual feel on the animated square.

  3. Step 3
    Copy CSS

    Use the generated keyframes + animation declarations directly.

In-depth guide

CSS animation generator

Create reusable keyframes and animation shorthand without manually tuning each value.

Animation shorthand order

animation commonly combines name, duration, timing-function, delay, iteration-count, direction and fill-mode.

Performance guidance

Prefer animating transform and opacity. Avoid layout-triggering properties like width/left where possible.

When to use it vs alternatives

Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.

Step-by-step usage

  1. Tune motion — Set duration, delay, easing, rotation and scale values.
  2. Preview animation — Verify the visual feel on the animated square.
  3. Copy CSS — Use the generated keyframes + animation declarations directly.

Common pitfalls

  • Check the result before replacing the original input.
  • Watch for unit, format, encoding, and browser memory limits on large inputs.
  • Keep a copy of important source material until the output is verified.

Privacy and security

Browser-first by design. The tool page explains any exception before you use it.

Your input is handled in the browser wherever the tool can process it locally. EpitomeTool does not add an upload step unless a tool page explicitly says so.

Frequently asked questions

Can I use this output in production?

Yes. The output is standard CSS keyframes plus a valid animation shorthand.

Does this support custom cubic-bezier?

This first release includes common easing presets. A bezier graph editor is planned for a later sprint.

Will the animation run smoothly on mobile?

Yes. Transform and opacity are GPU-friendly animation properties on modern browsers.
