Usage

Resize image

Sharpen gives you the ability to resize images to your desired dimensions, for example:

sharpen resize -h 800 ./mushroom.jpg

With this command, a new image will be created with a height of 800 pixels while maintaining the original aspect ratio.

Convert image to a different format

Sharpen empowers you to easily change the format of your images. You can specify the output format using the -f or --format option:

sharpen format -f webp ./input.jpg ./output.webp

The filename is automatically derived from the input file, and if no output is provided, it will have the same name as the input with the chosen extension.

sharpen format -f png ./mushroom.jpg

For this command, the output image will be named mushroom.png.

Output to multiple sizes at once

You can also generate multiple resized images in one go:

sharpen resize -m200,400,600 ./input.jpg

This will create three images, output_200.jpg, output_400.jpg, and output_600.jpg, each with a different size.

This command will produce three images with heights of 200, 400, and 600 pixels, respectively, all from the same input image.

If you are having trouble using Sharpen, please check the following:
