PHP-Noise

About PHP-Noise

PHP-Noise is a free, open source tool for generating noise-pattern background images. Users customize parameters such as color (specified via RGB or HEX values), number of tiles, tile size, border width, and color calculation mode, or leave fields blank to generate a random image.

Generated images can be downloaded, with files retained on the server for 10 minutes, or retrieved as a base64 string. The tool also exposes an HTTP API (via noise.php with query parameters for color, tiles, tile size, border width, and mode) that returns results in JSON or base64 format, with a help parameter available to list all options.

The source code is available on GitHub, covering both the script and frontend. It is suited for developers who need programmatically generated or customizable noise background images for web projects.
