Convert-img

A high performance multi-threaded cli image conversion tool based on ImageMagick.

This project is for my personal use, but I hope it can help you. If you have any questions, please submit an issue.

This project is still in the experimental stage, and the API may change at any time.

Features

• Support for converting images in batches
• Support for multi-threaded conversion
• Support conversion of scale, resize, quality, format.

Installation

Download the latest version of the binary file from the release page. You can choose between cpp and cs versions.

cpp vs cs

The cpp version uses GraphicsMagick as the underlying library, and the cs version uses ImageMagick as the underlying library.

Performance wise I found ImageMagick is faster wise than GraphicsMagick so I recommend using the cs version. cpp version is still experimental but still available for use.
