Instant Pixel Patterns Generator – Patternify
Patternify is a free-to-use web application for designing stripe patterns without using any image editing application.
The pattern can be drawn pixel-by-pixel over a custom-sized canvas, where the design can be previewed live, with the colors and opacity wanted
Once it is complete, the output can be downloaded as a .PNG file or you can use the generated base64 CSS code instead.
Patternify also creates a unique link for each pattern design for easily sharing them with others.
