Instructions

Software Usage Instructions

Set basic parameters: In “Basic Settings,” choose a sample preset, common size, or manually enter the width and height, then set the generation quantity, output format, image quality, file name prefix, and random seed.
Configure the color scheme: In “Color Scheme,” add, delete, or adjust color stops. You can also choose analogous colors, complementary colors, triadic colors, or light/dark variations of the same color to give each batch of images a consistent style.
Adjust gradient effects: In “Gradient Effects,” choose linear, radial, conic, mesh, light streak, or bevel gradients, and set the angle, center position, number of layers, softness, blend mode, grain, vignette, light spots, and streamline intensity.
View real-time preview: A preview image will be generated on the right based on the current settings. After modifying parameters, you can wait for the automatic refresh or click “Refresh Preview” to view the effect again.
Generate images in batch: After confirming the settings, click “Generate Batch Images.” The page only displays the first 20 thumbnails; images not shown will still continue to be processed and added to the download package.
Download results: After processing is complete, click “Download All Results (ZIP)” to get all images. You can also download the current preview image or copy the CSS background code in “Preview Download.”

FAQ

A: Linear gradients transition along a specified angle and are suitable for banners and page backgrounds; radial gradients spread outward from the center and are suitable for focused visuals; conic gradients transition around the center in a circular rotation and are suitable for decorative visuals; mesh gradients are created by overlaying multiple soft color blocks and are suitable for modern covers and product backgrounds.

A: You can keep the same color set and random seed while enabling “Slight variation per image” and “Random stops.” This keeps the overall color tone consistent while varying the color block positions, layers, and details in each image.

A: To reduce page load, the thumbnail area only displays the first 20 images. The generation task will continue processing all images, and the ZIP download will include all results generated in this session.

A: PNG is suitable for design assets that need lossless preservation; JPG is suitable for general background images and batch output, with smaller file sizes; WEBP is suitable for page assets that need to balance clarity and file size.

A: The random seed is used to reproduce the same set of random effects. When the size, colors, parameters, and seed are the same, regenerating will produce images with the same style and arrangement; changing the seed will produce a new random combination.

A: No. Image generation, previewing, and ZIP packaging are all completed on the current device, with no need to upload images or parameter files to the server.

A: You can reduce the number generated at once, lower the export scale, switch to JPG or WEBP, and reduce the number of layers and texture intensity. 4K or multi-scale exports use more memory and are better processed in batches.
