What's this?

The Mosaic Pattern Generator is a lightweight web app built to help you create beautiful, tile-based mosaic patterns with ease. Whether you're designing a unique background, experimenting with generative visuals, or simply exploring creative color arrangements, this tool provides a fun and flexible way to build patterns from customizable tiles.

You can define your canvas size, tile size, and choose from multiple colors—each with individual opacity controls. The pattern automatically repeats to fill the screen, giving you a preview of how it might look in a real-world design. You can also toggle square dimensions, tweak the background color (with hue feedback), and export your results in both PNG and SVG formats.

The app supports presets via URL and saves your settings in LocalStorage, so you can easily share or return to your favorite configurations. With a minimal interface and smooth interactivity, it’s ideal for designers, developers, and anyone who loves generative design.

Whether you’re crafting visuals for web, print, or inspiration, this generator gives you control and creativity without code.
