Online CSS Pattern Generator Patternify
Patternify is a simple web application for bloggers and web designers to quickly generate stripe pixel pattern online. The pattern can be drawn pixel-by-pixel over a custom-sized canvas with a live preview, with the colors and opacity wanted. Draw your pattern on the grid. You can use the cursors to limit the drawing surface and control the tiling. You build your pattern online with the base64 code without using any image editing application.
Once you complete the pattern design, you are allowed to download the .PNG image file or copy the code to your CSS file. Moreover, you can also share your pattern with an unique URL to other pattern aficionados.
