Where -o tells cwebp to write out to a file, %~n1 prints the name of the original file without the file extension, to which we add our new extension. %1 is the first argument supplied to the batch file, in this case, it will be the file we selected and right-clicked in Windows Explorer. v Print extra information (encoding time in particular).įor more information on command line switches that you can use with cwebp, see Google's WebP Guide on cwebp mt Use multi-threading for encoding, if possible. sharpness 0 Sharpness range with 0 being the most sharp and 7 being the least sharp f 50 Deblocking filter (Smoothness) (0-100) 6 is the maximum so we get the smallest file size. m 6 The compression method with values ranging from 0 to 6. q 50 The "compression factor for RGB channels between 0 and 100" In this step we will be creating a batch file that looks something like this: cwebp -q 50 -m 6 -af -f 50 -sharpness 0 -mt -v -progress %1 -o %~n1.webpĬwebp This references a specific executable file located in our libwebp's bin folder that can convert images to webp. The location of libwebp's bin folder has now been added to your PATH (environment variable.) Step 3: Create a batch file that converts a file to. If the folder was extracted inside a user's download folder, and that user was named "Administrator", then the folder location string would look like the following: C:\Users\Administrator\Downloads\libwebp-1.1.0-windows-圆4\binĪfter ensuring the path is correct, press enter.Ĭlick OK on the "Edit Environment Variable" Dialog.Ĭlick OK on the "Environment Variables" Dialog.Ĭlick OK on the "System Properties" Dialog.
