Getting cwebp, dwebp, and the WebP Libraries
cwebp encodes images in either JPEG, PNG or TIFF format into WebP, while
dwebp decodes them back into PNG. For a quick and easy way to get started
converting your images, the following archives are available on the
libwebp-0.6.0-windows-x86.zip : 32-bit executables and libraries for Windows-x86 platform.
libwebp-0.6.0-windows-x64.zip : 64-bit executables and libraries for Windows-x64 platform.
libwebp-0.6.0-linux-x86-32.tar.gz : 32-bit executables and libraries for GNU/Linux-x86 platform.
libwebp-0.6.0-linux-x86-64.tar.gz : 64-bit executables and libraries for GNU/Linux-x86_64 platform.
libwebp-0.6.0-mac-10.12.tar.gz : 64-bit executables and libraries for Mac OS X 10.12 (Sierra) platform.
All these archives contain both the
executables, along with the
libwebp.a library and C headers (the latter
allowing you to add WebP encoding or decoding to your own programs).
Note (for Linux and Mac OS X):
The 32 and 64-bit GNU/Linux binaries have been dynamically linked to the jpeg, png and tiff libraries. These libraries should be available on your system. However, if starting the binaries prints an error about the availability of libpng, libjpeg or libtiff, check the section Preparing the Platform on this page for installing them on your system.
Conversely, the libpng, libjpeg and libtiff libraries have been statically linked in the Mac OS X binaries. They do not require additional installation.
Installing cwebp and dwebp on OS X with MacPorts
An easy way to build and install the encoder and decoder on Mac OS X is by using MacPorts.
If you already have MacPorts installed, go directly to Step 3. Otherwise, follow these steps:
Install MacPorts according to the documentation.
sudo port selfupdate
sudo port install webp
Step 4 will install any dependencies, including the JPEG, PNG and TIFF libraries.
Note: Although the MacPorts repository is quick to add new WebP releases, their version may be out-of-date for a short while after each official WebP release.
Go to Using WebP for instructions on how to start converting your images.
