![]() Important: always use the command line options before the files to process and use double quotes when parameters or paths contain spaces, for example: gif2webp.exe -q80 -u "C:\My Pictures\Some GIFs" Alternative way of setting optionsīecause the tool is also meant to be used from the Desktop, there is an alternative to command line switches. If it decides to not collapse them, 100ms will be the new frame duration. If this switch is not used, the tool will try to guess whether to collapse subsequent frames or not. gif file with invalid frame duration is encountered, use X as the amount of milliseconds to use instead of 0. This parameter can be used to generate custom reports or to suppress all messages. -o - customize the messages sent to the standard output.-c - lets you change the output folder.Otherwise, files are always converted and overwritten. -u - do not process a file if the converted image already exist and is not older than the source file.-e - copy modification date from the original file (in addition to the creation date, which is always copied).If just -b is used, pixels are not mixed with background. The color is used when making semitransparent pixels opaque. -bXXXXX - (GIF only) X is a color value given in hexadecimal web format.Pixels more transparent than the given value are made transparent, others are made opaque. -lX - (GIF only) X is a value between 0 and 255 (55 by default) and defines how to handle semitransparent pixels.The resulting files will be about 5% smaller, but the conversion may take significantly more time. -q - (APNG only) use the zopfli compression algorithm.Higher number means higher quality and larger files, lower number means lower quality and smaller files. The X value sets the compression quality. -qX - (WebP only) use lossy compression instead of the default loss-less compression.-r - recursively scan all sub-folders of the given folder.The tools accepts the following command line options: The tool will automatically convert all compatible images to the target format and place them in the same folders as the originals. In the later case, place a tool on your Desktop and then drag and drop files or folders onto it. The tools can be used either from command line or from Windows Desktop. Animated WebP files can use lossless or lossy compression. In other browsers, the WebP images and animations are not displayed. WebP is a new file format supported in Google Chrome. In other browsers, only the first frame of the animation is shown. Because it is limited to 256 colors and cannot encode semitransparent pixels, other file formats have been designed to overcome these limitations.Īnimated PNG is backward compatible with ordinary PNG and is supported by the Mozilla Firefox browser. The GIF file format is widely used to encode simple animations. apng2gif - anmated PNG -> GIF conversion.apng2webp - anmated PNG -> WebP conversion.webp2apng - WebP -> animated PNG conversion.gif2apng - GIF -> animated PNG conversion.The web-ani-tools.zip package contains four separate tools for converting GIF, PNG and WebP animations. ![]()
