Meld is packaged for most Linux/Unix distributions, including Fedora, Ubuntu, and Suse. Unless you want the absolutely latest version, you should install Meld through your package manager. You can install MacPorts into a local directory without admin.
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 startedconverting your images, the following archives are available on thedownloads repository.
libwebp-1.2.0-windows-x64.zip : 64-bit executables andlibraries for Windows-x64 platform.
libwebp-1.2.0-linux-x86-64.tar.gz : 64-bit executables andlibraries for GNU/Linux-x86_64 platform.
libwebp-1.2.0-mac-10.15.tar.gz : 64-bit executables andlibraries for Mac OS X 10.15 (Catalina) platform.
All these archives contain both the
dwebp precompiledexecutables, along with the
libwebp.a library and C headers (the latterallowing you to add WebP encoding or decoding to your own programs).
Note (for Linux and Mac OS X):
The 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.
OS X Package Managers
Additionally, the WebP tools are often available for Mac OS X via Homebrewand MacPorts.
