I have been working with a lot a photos I take during my walks in NYC and when I travel to visit coffee farms in Latin America. I needed an efficient way to process my images for the web. I put these brief instructions together. You can also make this a script and process images in bulk.
To convert a JPG image to WebP format using ImageMagick, you can follow these steps:
Install ImageMagick: Make sure you have ImageMagick installed on your computer. You can download it from the official website (https://imagemagick.org/) and follow the installation instructions specific to your operating system. If you’re on a mac you can always use brew to install this.
Use the following command to convert the JPG image to WebP:
magick inputFile.jpg outputFile.webp
Adjust compression quality (optional): By default, ImageMagick will use a compression quality of 75. If you want to adjust the compression quality, you can add the
-quality option followed by a value from 1 to 100. For example, to set the quality to 90, modify the command as follows:
magick inputFile.jpg -quality 90 outputFile.webp
Remember to replace “magick” with “convert” if you are using an older version of ImageMagick.
