ImageMagick for Windows

ImageMagick is a free and open-source software suite that is widely used for working with raster and vector images. It provides a set of command-line tools and libraries that allow users to manipulate images in various ways, including converting between different image formats, resizing, cropping, rotating, applying filters and effects, and much more.

Features

• Format conversion: convert an image from one format to another (e.g. PNG to JPEG)
• Transform: resize, rotate, crop, flip or trim an image
• Transparency: render portions of an image invisible
• Draw: add shapes or text to an image
• Decorate: add a border or frame to an image
• Special effects: blur, sharpen, threshold, or tint an image
