Instructions

Software Usage Instructions

Select a style: First, in the “Select Style” step, choose sample presets such as Ocean Blue Waves, Warm Sun Ripples, Forest Green Flow Lines, or Blue-Gray Tech. You can also click Random Style to quickly get different color schemes.
Set the canvas: Choose common sizes such as website banner, Full HD, 4K, social cover, or vertical poster, or manually enter the width and height on the parameters page.
Adjust wave parameters:
- Frequency: Controls the number and density of waves.
- Amplitude: Controls the vertical rise and fall of the waves.
- Randomness: Creates natural variations in the wave curves.
- Layer spacing: Adjusts the distance between multiple wave layers.
- Smoothing and grain: Used to add texture to the background.
Manage layers: You can add or delete wave layers and set each layer’s start color, end color, opacity, and vertical offset separately.
Export files: In the “Export Files” step, choose SVG or PNG format, click “Download Background” to save a single background, or click “Copy SVG Code” for use in webpage code.
Batch generation: After setting the quantity, format, and variation range, click “Generate Batch Preview.” The interface displays the first 20 images, and the ZIP download will include all generated results.
Save settings: Click “Save Settings” to keep the current parameters, and click “Load Saved Settings” to restore them next time.

FAQ

A: SVG is suitable for webpage backgrounds, responsive interfaces, and scenarios that require scaling; PNG is suitable for fixed-size images, cover images, presentations, and scenarios where embedding SVG is inconvenient.

A: We recommend using 3 to 5 layers, keeping the frequency between 4 and 8, setting the amplitude to 60 to 120px, controlling randomness between 15% and 35%, and using similar but not identical opacity values for different layers.

A: To keep page operations smooth, the preview area only displays the first 20 images. During actual packaging, the full quantity you set will be processed, and the ZIP file will include all generated results.

A: They can be used for web banners, landing page backgrounds, product introduction sections, event covers, social media images, presentation backgrounds, UI decorative areas, and more.

A: You can lower layer opacity, reduce randomness and grain intensity, choose softer background colors, and keep the waves concentrated at the top or bottom to leave a clean area for text.

A: The current canvas size, background color, wave parameters, layer colors, opacity, export format, batch parameters, and more will be saved, making it easy to continue adjusting the same style later.
