To use the plugin, put the file found in the bin folder inside your Photoshop plugin directory: WebPShop 0.2.1, released under the Apache License 2.0 license, is a Photoshop module for opening and saving WebP images, including animations, and can be found at. If you're a Photoshop user, you need a plugin to convert the files, as Photoshop does not include it natively. From version 2.10 on, it supports WebP natively. To convert images to WebP with a photo editor, use GIMP. Free online course: RHEL technical overview.It offers several options for quality and compression profile: The open source image editor GIMP supports WebP as an export format. By converting it to WebP, I reduced the file size to 45 KB, and there was no discernible loss in quality. On one graphic I tested, the original web version was 650 KB in size. Each audit has a reference doc explaining why the audit is important, as well as how to fix it." Creating a smaller WebP image From there, use the failing audits as indicators on how to improve the page. You give Lighthouse a URL to audit, it runs a series of audits against the page, and then it generates a report on how well the page did. You can run Lighthouse in Chrome DevTools, from the command line, or as a Node module. It has audits for performance, accessibility, progressive web apps, SEO, and more. You can run it against any web page-public or requiring authentication. Īccording to its official description, "Lighthouse is an open source, automated tool for improving the quality of web pages. To test the speed of one of the pages, I turned to web.dev, which is powered by Lighthouse, released under the Apache 2.0 license, and can be found at. Since the website is a marketing tool and site speed is a critical aspect of the user experience, I have been working to improve the speed, and reducing image sizes by converting them to WebP has been a good solution. Part of my job is to design and maintain our organization's website. The workaround for this is to serve up a JPG/PNG alongside a WebP, and there are methods and Wordpress plugins to do that. At the time of this writing, it is not compatible with Apple's Safari browser. The WebP format is compatible with vast majority of the web browsers in use worldwide. The standalone libwebp library serves as a reference implementation for the WebP specification and is available from Google's Git repository or as a tarball. The WebP file format is based on the RIFF (resource interchange file format) document format. Google reports a 64% reduction in file size for images converted from animated GIFs to lossy WebP, and a 19% reduction when converted to lossless WebP. For cases when lossy RGB compression is acceptable, lossy WebP also supports transparency, typically providing three times smaller file sizes compared to PNG. Lossless WebP supports transparency, as well. WebP lossy images are often anywhere from 25-34% smaller than comparable JPEG images at equivalent SSIM (structural similarity) quality index. WebP lossless images are often at least 25% smaller in size compared to PNGs. A faster loading website is critical to the user experience and for the website's marketing effectiveness.įor optimal loading across all devices and users, images on your site should not be larger than 500 KB in file size. Using WebP, web developers can create smaller, richer images that improve site speed. WebP is an image format developed by Google in 2010 that provides superior lossless and lossy compression for images on the web.
