webpmux
Manipulate WebP metadata and animation
TLDR
SYNOPSIS
webpmux [-get|-set|-strip] [options] input [-o output]
DESCRIPTION
webpmux is a tool from Google's libwebp library for manipulating WebP image files at the container level. It can extract and set metadata profiles (ICC color, XMP, EXIF), extract individual frames from animated WebP files, and combine frames into animations.The tool operates on the WebP container format without re-encoding the image data, making operations fast and lossless. Metadata can be stripped from files to reduce size, or added to include color management and descriptive information.For animated WebP files, individual frames can be extracted as separate WebP images, and frame timing and looping parameters can be inspected with the info command.
