SVG Wave Generator
Free online SVG wave generator: stack 1-5 smooth wave layers, tune baseline, amplitude, wavelength and smoothness, apply a two-color gradient and export the vector code.
What does the SVG Wave Generator do?
It builds decorative wave shapes as ready-to-use SVG markup. You can stack 1-5 layers, each with its own baseline height, amplitude, wavelength and smoothness, and fill them all with one shared two-color linear gradient.
How are the wave curves drawn?
Each layer is produced by a self-contained path generator: the wave is split into half-wavelength segments and every segment is drawn with cubic Bezier control points. This keeps the file tiny and perfectly smooth at any zoom level.
What does the smoothness slider change?
At 0% the segments become straight lines and the wave looks like a zigzag. Raising the slider moves the Bezier control points outward, so at 100% you get full sine-like curves.
Where can I use the exported SVG?
Anywhere HTML or SVG is accepted: hero backgrounds, dividers between page sections, footers, presentations and design tools. Paste the copied markup straight into your HTML or save the .svg file from the Download button.
Will the wave stay sharp at any size?
Yes. The export keeps a 1440x480 viewBox, so the graphic is pure vector geometry. Stretch it to 100% page width or scale it up for print and the curves never blur or pixelate.
How does the Randomize button work?
It picks a fresh random layer count between 1 and 5, new random values for every layer parameter and two random harmonious colors, then redraws the preview instantly. Press it repeatedly until you like the result.
Can I use my own brand colors?
Yes. The two color pickers set the start and end stops of the linear gradient that every layer shares, so changing them recolors the whole wave group at once.
Is any data uploaded to a server?
No. The generator runs entirely in your browser with plain JavaScript. Your colors and settings never leave the page, and the exported file is created locally on your device.
How to Use SVG Wave Generator
The SVG Wave Generator creates layered wave shapes as clean, ready-to-paste SVG code. Every layer is a smooth cubic-bezier curve filled with a shared two-color linear gradient, which makes it perfect for hero section backgrounds, page dividers and footer decorations. Everything is generated in your browser — nothing is uploaded.
- Pick how many layers (1-5) you want in the Layers selector. Layers are drawn back to front, so each new layer paints over the previous ones.
- Choose the gradient start and end colors with the two color pickers — every layer shares this linear gradient.
- Fine-tune each layer with its four sliders: Baseline height moves the wave up or down, Amplitude sets how tall the crests are, Wavelength controls the horizontal distance between crests, and Smoothness blends from straight zigzag lines (0%) to full sinusoidal cubic-bezier curves (100%).
- Press Randomize to instantly generate a fresh combination of layer counts, shapes and colors until something looks right.
- Press Download SVG to save a .svg file, or Copy source to put the complete SVG markup on your clipboard, ready to paste into any HTML file or design tool.
For website section dividers place the SVG between two blocks and let it stretch to 100% width — the viewBox keeps the curves undistorted at any size. Lower smoothness with short wavelengths gives a hand-drawn look, while full smoothness with long wavelengths looks like a calm sea.
