![]() ![]() The number of variants Webflow generates depends on the image's original size. How many variants are generated per image? We recommend SVGs and PNGs for high detail or vector based images, since these have lossless compression. It also doesn't apply to background images. This feature generates responsive variants for all inline JPGs, PNGs, and WebP images, except those added via rich text elements. Common questions about responsive images What are the supported image types? For example, you may need to set the image's width to 100% to fill its container. In some cases, you may need to add additional styling to override the sizes attributes effect on image element dimensions. After adding hover state styles or interactions, it's a good idea to go through your site and make sure everything looks okay before publishing. Webflow creates responsive images from their normal states - not their hover states or interactions that may change the size of the image. Manage responsive images with interactions Type Command + Shift + O (on Mac) or Control + Shift + O (on Windows).To disable this feature for a specific image (e.g., if you need to force the browser to use the original image size): If you'd rather do this later, you can start the process anytime from the Asset panel or by using the shortcut Command + Shift + I (on Mac) or Control + Shift + I (on Windows). This process can take a few minutes, depending on the size of your site. The next time you open the Designer, you'll see a modal asking you to start the migration process. If you created your site before September 14th, 2016, you'll need to walk through a quick process to generate responsive images on your site. ![]() Generate responsive images for sites built before September 2016 To ensure that all your images remain responsive, you can either visit the affected page, or use the shortcut Command + Shift + I (on Mac) or Control + Shift + I (on Windows), and the Designer will scan and re-measure all your pages for you. ![]() But you may make changes that affect images on other pages (e.g., updating a Symbol or class). Webflow measures your images and generates responsive variants as you work on a site page. Manually generate responsive images across a site Important: If your original images are compressed enough, Webflow uses your original images. To give the browser access to different sized versions of images, Webflow creates a set of variants for each image upon upload, then encodes instructions for your browser to know when to serve each variant. Making an image responsive means that your browser serves a different sized version of that image based on the size of the image on your page and the screen resolution (by adding srcset and sizes attributes to your elements). This can help your mobile pages load up to 10 times faster. When you upload images to your site, Webflow creates variants of your uploaded images to make sure they’re responsive and load quickly on any device. There is an original image and then variants with sizes of 2000px, 1600px, 1080px, 800px, and 500px. Want to understand the technical details? Read more.Webflow-created variants of an uploaded image. Images are analyzed to find the best breakpoints on an image by image basis, rather than creating all possible image resolutions, and enables developers to easily create 'picture' and 'img' HTML5 elements based on the calculated breakpoints. The algorithmic concept is to find image width values that offer a significant reduction in file size. To solve this problem, our breakpoint generator tool uses Cloudinary's advanced algorithms to easily generate best matching breakpoints for each uploaded image. This breakpoints generator tool helps developers automatically find the optimal image sizes needed for the best viewing experience in web and mobile apps on a variety of screen sizes.Ĭommon responsive image solutions tend to generate images based on a fixed set of image width values, disregarding the actual saving in file size bytes. Responsive web design requires developers to determine the image dimensions that best fit their website. ![]() It's time to solve these issues and start calculating image breakpoints more mathematically, rather than haphazardly. They compromise on either the image dimensions or the number of images. Responsive websites, even the most modern ones, often struggle with selecting image resolutions that best match the various user devices. ![]()
