To specify the compression factor for RGB channels between 0 & 100. This option is useful only if the input image/filename starts with an ‘-‘. If this option is omitted, cwebp will perform compression but will only report the statistics using “-” as the name of the output file/image name. To explicitly specify the name of the output webp file. Using cwebp to compress a 2.1 MiB jpg image to 983 Kib webp image (52% lossless compression) In the below example, using cwebp command without using -q option, so by default, it is 75. In the above command, the quality compression factor is 80. User can convert a PNG image file to a WebP image format with the quality range of 0 to 100 with the following command : cwebp -q 80 image.png -o image.webp Converting Images to the WebP Format using cwebp tool:
Note: Animated PNGs and WebP files are not supported.

Precompiled WebP utilities and library for download are also available : LinuxĬwebP compresses the image using WebP format. WebP: Getting started Download the pre-compiled packages for different OS (s) :Īll the WebP packages are available in Google’s official downloads repository. Note: WebP can also be displayed in all major browsers using the WebPJS JavaScript library, although support in Internet Explorer 6 and above is achieved using Flash. Safari also has added support for WebP format files and images with iOS 14 and macOS Big Sur.Versions of Microsoft Edge based on EdgeHTML support WebP via a platform extension that is installed by default.Google Chrome and all Chromium-based browsers,.Horizontal differences b/w pixels in A (starting from P) are generated using the pixels from L to start each row. TM_PRED (TrueMotion prediction): It uses pixel P above & to the left of the block.DC_PRED (DC prediction): It fills the macroblock with a single value based on the avg of the pixels in the row above A (V_PRED) & the column to the left of L (H_PRED).V_PRED (vertical prediction): It fills every row with the macroblock with the generated copy of the above row denoted by A.H_PRED (horizontal prediction): It fills every column with the macroblock with the generated copy of the left column of the same denoted by L.These macroblocks share the following 4 common intra-prediction modes : The image frame is “key” in the sense that it only uses the pixels already decoded in the immediate spatial neighborhood of each of the macroblocks & tries to recover the unknown parts and uniquely identify the macroblock.Within each macroblock, the encoder ( a process to convert data from one format to another, in this case, one image format like jpeg/png to webp) can predict redundant motion & color information based on previously processed macroblocks.You don’t have to remember every technical jargon associated with this technology. VP8 divides the frame into smaller segments called macroblocks. VP8 is based on block prediction & like any block-based codec. It is loss compression process uses the same methodology as VP8 (created by On2 technologies, which is a royalty-free video compression format) for estimating (video) frames. Images in webp format are 26% smaller compared to PNGs and also are 25-34% smaller than respective equivalent JPEG images.

Through WebP, web developers and software engineers can create smaller, richer images that make their web application faster, improve performance and google SEO ranking. Google acquired On2 Technologies & its video products & technologies in February 2010.
It is currently developed and supported by Google, based on technology acquired with the acquisition of On2 Technologies.It is a new image format for the web employing both loss and lossless compression.
