SVG Wave Generator

What is an SVG wave generator?

An SVG wave generator is a free browser-based tool that lets you create smooth, scalable wave shapes for use as website hero section dividers, footer separators, and section background transitions. Unlike raster images, SVG waves are resolution-independent — they scale sharply at any screen size without pixelation, load fast at under 2 KB, and can be animated with CSS keyframes embedded directly in the markup.

This tool supports up to four independent layers with separate amplitude, frequency, opacity, and fill settings, so you can produce subtle multi-depth wave effects without leaving the browser. After configuring your wave you can export it as raw SVG, inline HTML, React JSX, Vue SFC, or a CSS background-image data-URI — all 100% client-side with no signup required.

How to use the SVG wave generator

• Choose a preset or start from scratch: Click any preset in the gallery row to load a ready-made parameter set, or skip the presets and adjust sliders directly.
• Configure global settings: Set the number of layers (1–4), export width and height (or pick an aspect preset such as Hero 1440x400 or Footer 1920x200), and tweak the curve-smoothing and roughness sliders.
• Adjust each layer: Expand a layer card to set its amplitude, frequency, vertical offset, opacity, fill mode, and colors independently. Use the Randomize button to generate a fresh seed for all layers at once.
• Enable animation (optional): Toggle the Animate switch, then set the speed and scroll direction. The preview updates live.
• Export your wave: Select an output tab (SVG, HTML, React, Vue, or CSS), copy the code with the copy icon, or click Download SVG or Download PNG to save a file.

Wave shape controls explained

Each control affects a different aspect of the path geometry:

Solid vs gradient wave fills

Each layer supports two fill modes. Solid fills the entire wave path with a single flat color — this is the simplest option and produces the smallest SVG output, which is ideal for single-color brand backgrounds. Gradient emits a linearGradient element in the SVG defs block with two color stops and an adjustable angle slider (0–360 degrees). You can pick completely different colors for each layer's gradient, which produces layered sunset or ocean effects when layers overlap at different opacities.

The CSS Gradient Generator is a companion tool if you need a standalone gradient background rather than a wave shape.

How to add an SVG wave to your website

There are four main ways to embed the generated wave depending on your stack.

Inline HTML

Copy from the HTML tab and paste the <svg> tag directly into your markup. The wave fills its natural dimensions and can be further styled with CSS.

React / Next.js

Switch to the React / JSX tab. The output is a self-contained functional component with camelCase attribute names (stopColor, clipPath) ready for JSX. Import and render it anywhere in your component tree.

Vue SFC

The Vue tab wraps the SVG in a <template> block, ready to paste into a .vue file.

CSS background

The CSS Background tab generates a background-image: url("data:image/svg+xml;utf8,...") rule with background-size: cover. Paste this into any CSS class — no file hosting needed. Note that the CSS data-URI method does not support animation; use the inline SVG approach for animated waves.

How to create an animated SVG wave

Toggle the Animate switch in Global Settings. The generator automatically embeds a @keyframes block and a matching animation property inside the SVG <style> element. Each layer gets its own named keyframe that translates the path by one wave period, so the wave tiles seamlessly in a continuous loop.

Use the Speed slider to set the loop duration (1–20 seconds). Use Direction (LTR or RTL) to control which way the wave scrolls. The animation is self-contained — it plays in any browser that supports inline SVG, including all modern versions of Chrome, Firefox, Safari, and Edge. Because the animation uses CSS transforms rather than SMIL, it also works inside React and Vue renders.

One important limitation: CSS background-image: url(data:...) does not run CSS animations. If you need an animated wave, use the inline HTML or JSX output and embed the SVG directly in your page.

SVG vs CSS waves — which to use?

SVG waves are the preferred choice for web projects because they are design-tool-friendly, easy to export as PNG for fallback environments, and supported by all major browsers. The Blob Generator follows the same SVG-first approach for organic non-wave shapes.

Common use cases

• Hero section dividers: Place a wave at the bottom of the hero block to create a smooth transition into the next section. The 1440x400 aspect preset is sized for this use case.
• Footer transitions: Flip the wave vertically (Flip V) and position it above the footer for a natural flowing look. The 1920x200 Footer preset gives a shallower profile suited to this.
• Section break backgrounds: Use a multi-layer wave at full viewport width with low opacity layers to create depth without heavy imagery.
• Landing page graphics: Gradient waves with the Layered Sunset or Ocean presets make eye-catching call-to-action backgrounds without stock photos.
• Mobile app onboarding: The Mobile 375x120 preset produces a compact wave optimized for onboarding screen backgrounds.
• Email header graphics: Download the PNG export and use it as an email header image — SVG is not supported in most email clients but a rasterized PNG exports cleanly.

Tips for crisp, performant SVG waves

• Keep the frequency slider at 3–5 for smoothest results. Very high frequencies can create visual noise that is hard to read at smaller viewports.
• Use opacity layering rather than many separate colors for multi-depth effects. Two layers at 100% and 60% opacity of the same hue look more cohesive than four different colors.
• Set viewBox="0 0 W H" without a fixed width and height for a fully responsive embed — the browser will scale the wave to fit its container.
• For animated waves, prefer will-change: transform on the wrapping element in your CSS to hint the browser to promote the layer to the GPU compositor.
• The Drop Shadow Generator can add a subtle shadow below the wave shape in CSS to increase perceived depth on light backgrounds.
• When exporting PNG for email or social media, use the native export width (1440 or 1920) rather than scaling up a small canvas — the PNG export renders at the configured dimensions.

Frequently Asked Questions (FAQs)

What is an SVG wave generator?

An SVG wave generator is a free browser tool that lets you create smooth, scalable wave shapes for website hero dividers, footers, and section separators. You configure amplitude, frequency, layers, and colors, then export the result as raw SVG, HTML, React JSX, Vue SFC, or a CSS data-URI background.

How do I create an SVG wave for my website?

Open the SVG Wave Generator, adjust the amplitude and frequency sliders until the wave looks right, pick a fill color or gradient, then click Download SVG or copy the SVG code. Paste the code directly into your HTML or React/Vue component.

Are the SVG waves free for commercial use?

Yes. Every wave generated by this tool is 100% yours — there is no watermark, no attribution requirement, and no license restriction. Use them freely in personal and commercial projects.

Can I export the wave as PNG, JSX, or CSS instead of SVG?

Yes. The output panel has tabs for SVG, HTML, React/JSX, Vue SFC, and CSS background (data-URI). A Download PNG button renders the current frame to a canvas and saves a raster PNG at your configured width and height.

How do I make the SVG wave animated?

Toggle the Animation switch in the global controls. The generator embeds a CSS @keyframes translateX animation directly inside the SVG so it loops seamlessly. Adjust the speed and direction (LTR or RTL) sliders as needed.

How do I add multiple layered waves?

Use the Layers stepper (1–4) at the top of the controls panel. Each layer gets its own amplitude, frequency, vertical offset, opacity, fill mode, and color settings — they are stacked into a single SVG output.

Why use SVG waves instead of PNG/JPG backgrounds?

SVG waves are resolution-independent (they look sharp on any screen density), typically under 2 KB in file size, and can be styled or animated with CSS. PNG/JPG backgrounds are fixed resolution, heavier, and cannot be animated this way.

How do I add the SVG wave as a CSS background?

Switch to the CSS Background tab in the output panel. Copy the generated background-image rule and paste it into your stylesheet. The rule uses a URL-encoded data-URI so no external file is needed.

How do I add an SVG wave divider in React or Next.js?

Switch to the React / JSX output tab. The generated code is a ready-to-use functional component with camelCase attributes and a proper xmlns. Paste it into your project and import it wherever you need the wave divider.

Does the generator work offline / is my data sent to a server?

All wave generation, preview, and export is handled entirely in your browser using JavaScript. No data is sent to any server. The tool works offline once the page has loaded.
