img-convertor

img-convertor is a command-line tool based on Node.js and the Sharp library for batch image conversion and resizing. It supports various image formats and can recursively process all images in the specified directory.

Installation

Before using this tool, ensure that Node.js and npm are installed. Then run the following command to install the tool globally:

npm install -g img-convertor

Usage

This tool provides two main commands: converter and resize.

1. Convert Image Formats

Use the converter command to convert the format of all images in a directory:

converter <sourceTypes> <targetType>

<sourceTypes>: The source image formats to convert (e.g., png,jpg,jpeg). Optional, defaults to png,jpg,jpeg,webp,gif,bmp.
<targetType>: The target image format (e.g., png, jpeg, webp). Optional, defaults to png.

Example:

converter jpg png

Converts all .jpg images in the current directory to .png format and saves them in the output directory.

2. Resize Images

Use the resize command to resize images:

resize <sourceTypes> <targetType> <width> <height>

<sourceTypes>: The source image formats to resize (e.g., png,jpg,jpeg). Optional, defaults to png,jpg,jpeg,webp,gif,bmp.
<targetType>: The target image format (e.g., png, jpeg, webp). Optional, defaults to png.
<width> and <height>: Specify the target width and height of the images in pixels.

Example:

resize jpg png 800 600

Converts all .jpg images in the current directory to .png format, resizes them to 800x600 pixels, and saves them in the output directory.

Supported Image Formats

Input formats: png, jpg, jpeg, webp, gif, bmp.
Output formats: jpeg, png, webp, tiff, gif, avif, svg.

Notes

The converted or resized images will be saved in the output folder in the current directory.
If <sourceTypes> and <targetType> are not provided, the program will use default values.
For resizing images, both width and height parameters are required.

Dependencies

This tool is built on the sharp library. Please ensure your environment supports this library.
