WebP is a modern, open source, image format that provides superior lossless and lossy compression ( as well as animation and alpha transparency ) for images on the web.
There are a lot of online tools that will allow you to convert your images but, why upload your images on a random server when you can easily convert them right on your computer?
Installing libwebp on Linux
You’ll find the necessary tools in your Linux’s distro default repositories. However, depending on the distro you’re running, libwebp is available under different names:
- Arch and derivates:
sudo pacman -S libwebp
- Ubuntu and derivates:
sudo apt install webp
sudo dnf install libwebp-tools
Installing libwebp on macOS
To install the necessary tools on macOS, you first need to have Homebrew installed.
Once Homebrew is up and running, you can install libwebp by running
brew install webp.
Converting images to WebP
The conversion process is identical on both Linux and macOS. Once you have libwebp installed on your OS, open up the terminal and:
cd into path ( where the image you want to convert is located )
cwebp original.jpg -o converted.webp ( replace original and converted with the appropiate names. for the converted pic, you can use whatever name you please )
2.1 you can use the
-q option to control the quality level. Generally, a level of 80-85 will give you good results. The command will be:
cwebp original.jpg -q 80 -o converted.webp
For the purposes of this article, I’ve used a 6K, 21MB photo. This is the result:
There’s a lot more flags that you can use. To see all the flags and options of libwebp, run
Converting Gif to WebP
By now, you might’ve tried to convert a .gif into .webp, which resulted in an error along the lines of “Error! Could not process file pic.gif”.
To convert a .gif file to .webp, run
gif2webp original.gif -o gif.webp.
Converting WebP to PNG
To convert any .webp file into a .png file you can run
dwebp original.webp -o image.png
