JS paint plugin for your website 🎨

The Painterro is a simple but powerful embeddable open-source JS paint for any website or webapp.

It allows very fast processing of raster images. Here we will review the features.

Cropping

🖼 By default selection tool is active, so you can start selecting interesting area just after you opened file in Painterro (which could be triggered by document.onpaste for example).

After selecting the area which you want to leave on image, just press crop once:
