Wave shapes are a popular design element for section dividers, backgrounds, and decorative accents. This tool generates a smooth, ready-to-use SVG wave from a few simple parameters — no design software required.

How it works

Set the wave's width, height, amplitude (how tall the wave peaks are), frequency (how many wave cycles fit across the width), and a color. The tool builds a single smooth path using cubic Bézier curves and wraps it in ready-to-use SVG markup you can copy directly.

  1. Enter width (px).
  2. Enter height (px).
  3. Enter amplitude (px).
  4. Enter frequency (cycles).
  5. Enter color.

Examples

A gentle section divider

A wide, low-amplitude, low-frequency wave (e.g. amplitude 20-40px, frequency 2-3) makes a subtle section-divider shape; a taller amplitude or higher frequency gives a bolder, busier pattern.

Who should use it

  • Website section dividers and decorative backgrounds.
  • Quick placeholder or prototype graphics.

Industry applications

  • Web design and front-end development
  • UI/UX prototyping

Advantages

  • Instant, copy-paste-ready SVG markup — no design software needed.
  • Fully deterministic and easy to regenerate with tweaked parameters.

Limitations

  • Produces a single smooth wave shape — more complex multi-wave layering needs manual editing afterward.

Common mistakes to avoid

  • Setting a very high frequency with a very high amplitude, which can make adjacent wave peaks visually crowd or flatten — try a lower frequency first if the shape looks off.
  • Forgetting to set `width`/`height` on the surrounding container to match the SVG's own dimensions, causing unexpected scaling.

Best practices

  • Preview a few frequency/amplitude combinations before settling on one — small changes can noticeably change the wave's character.
  • Use the SVG's built-in `viewBox` to let it scale responsively in your page layout.

Tips

  • Try setting the SVG's fill to a color and stroke to none for a solid wave "fill" shape instead of just an outlined line, by editing the copied markup directly.

Frequently asked questions

Yes, with no signup and no limit on how many waves you generate.
Yes — it's markup you generated from your own parameters, not a licensed asset, so there's no attribution or licensing restriction on using it.
Yes — this is a pure mathematical shape (no randomness involved), so identical settings always produce identical, reproducible output.
Yes — it's plain, readable SVG markup, so you can open it in any code editor or vector design tool and adjust the path, color, or dimensions further.
