Image editors to convert images to WebP for Ubuntu?

Question

Is there a good image editor application for Ubuntu with which I can convert jpg/png images into WebP format? ImageMagick was a crap for me! With it, output webp image's size just increased!!!

Answer 1

There is a plugin for the Gimp that provides the ability to load and export WebP images. You can install the package (gimp-webp) from this PPA:

ppa:george-edison55/webp (Click here for instructions on using PPAs.)

The commands for doing this would be:

sudo add-apt-repository ppa:george-edison55/webp
sudo apt-get update
sudo apt-get install gimp-webp

Once the package is installed, open up the Gimp and you will now be able to export images to the WebP format:

The package is currently available for Trusty, Utopic, Vivid, and Wily.

Answer 2

16.04 Fixed

Since 16.04 imagemagick (or convert) does support webp, although it delegates to webp, so you need to install webp.

sudo apt-get install webp

But importantly things like convert img.png img.webp do work now.

Before 16.04 convert simply gave a png or jpg as output. The result wasn't a webp format. (You probably got bigger filesizes because it converted jpg with default (higher) quality)

Thumbnails:

display 'vid:*.webp'

Answer 3

There is a webp package in Software Center by which you can convert GIF to WebP via commandline.

Also there's a paint for KDE, KolourPaint, which can save images as WebP.

Answer 4

Achieved using CLI

Windows:

> for /R . %I in (*.jpg) do ( cwebp.exe %I -o %~fnI.webp )

Linux / macOS:

$ for F in *.jpg; do cwebp $F -o `basename ${F%.jpg}`.webp; done

Note: replace .jpg with .png if PNG is what you are dealing with.
