ResizeGo

Resize multiple JPG images with high quality and low space

ResizeGo is a simple command-line tool written in Go that allows you to efficiently resize a collection of JPG images, optimizing for both high quality and reduced storage space. The tool supports concurrent processing for faster resizing and is designed to be easy to use.

Features

• Resize multiple JPG images concurrently
• Optimize for high quality with adjustable JPEG compression
• Efficiently reduce file size for better storage utilization
• Specify custom output directories for resized images
• Command-line interface for easy integration into workflows

Usage

1. Download the latest release or build from source.
2. Run the executable with the source directory as a command-line argument:

./resize_images source_directory

Resized images will be saved in separate output directories for high quality and low space versions.

Options

• -quality: Adjust JPEG compression quality (default is 80)
• -maxwidth and -maxheight: Set maximum width and height for resizing
• -output: Specify custom output directory names for different sizes

Requirements
