Color Swatch Image Generator - Online PNG Palette

A Color Swatch Image Generator is a free online tool that creates clean, professional PNG images from your chosen color palette. Designers use it to visualize color schemes, create palette references, share color combinations with clients, or generate assets for design documentation. Simply pick your colors, adjust layout settings, and export a high-quality PNG.

Configure your colors and layout settings, then click the "Export PNG" button. The tool renders your swatch on an HTML5 Canvas and downloads it as a lossless PNG image. You can customize the filename before exporting. The exported PNG uses the exact pixel dimensions shown in the preview info.

The tool accepts HEX color codes (6-digit, e.g., #FF6B6B) and also auto-expands 3-digit shorthand (#ABC → #AABBCC). You can use the native color picker, type hex values manually, or extract colors from an uploaded image. When copying, you can choose HEX list, CSS gradient, JSON array, or CSV formats.

Yes! Click the "Extract" button and upload any image (JPEG, PNG, WebP, etc.). The tool analyzes the image and extracts the 5 most dominant colors using frequency-based color quantization. This is perfect for building a palette inspired by a photograph, logo, or artwork.

Three layouts are supported: Horizontal (all swatches in a row), Vertical (stacked column), and Grid (arranged in rows/columns with configurable column count). You can also adjust swatch width/height, gap spacing, corner radius, canvas padding, and choose whether to show hex labels inside or below each swatch.

Absolutely. The PNG images you generate are entirely your creation — there are no watermarks, no attribution requirements, and no usage restrictions. You can use them in commercial projects, design mockups, presentations, social media, websites, or print materials without any limitations.

The Transparent option exports a PNG with alpha transparency behind the swatches — ideal for overlaying on other designs. The Checkerboard option renders a gray-and-white checkerboard pattern (common in image editors) to help visualize colors with transparency while keeping an opaque PNG. White fills the background with solid white.

Great palettes follow color theory principles: Analogous colors (adjacent on the color wheel) create soothing schemes; Complementary colors (opposite) provide vibrant contrast; Triadic (evenly spaced) offer balanced variety. Use the 60-30-10 rule: 60% dominant, 30% secondary, 10% accent. Test your palette for accessibility — ensure sufficient contrast ratios for text readability (WCAG recommends 4.5:1 minimum).
