![]() ![]() ![]() Occasionally browser support for different formats gets broken, even if a specific browser advertises that a particular format is supported. Cloudinary monitors the browser ecosystem, and thanks to a vast community of users, detects issues in browser support and immediately reacts. When it comes to selecting the best format, Cloudinary does not blindly select the format only by browser, and not even by the accepts-header. The automatic format feature provides live functionality under the hood, and as browser support evolves and changes, Cloudinary customers get continuously growing value as our serving is updated. The remote image is fetched by Cloudinary, stored persistently in the cloud, dynamically converted to AVIF, WebP or JPEG-2000 as required by the user’s browser and delivered optimized and cached through a high-end CDN. ![]() With Cloudinary’s automatic format feature, you can also dynamically convert and deliver remote images and improve your site’s performance.įor example, the following URL delivers a picture of Dwayne Johnson from a remote Wikimedia Commons HTTP URL. Simply prefix your image URLs with Cloudinary’s fetch URL. This means, for example, that you can easily integrate Cloudinary with your website without modifying your infrastructure and code. In addition to direct uploads, Cloudinary also supports fetching images via their public URLs, transforming these on-the-fly and delivering the resulting images optimized via a CDN. The example above demonstrates automatic format selection for images that were uploaded to Cloudinary first, either using our upload API from your server code or directly from your visitor’s browsers or mobile apps. The second image includes f_auto in its delivery URL and so is delivered as either an AVIF ( 14.6 KB – a saving of 56.5%), WebP ( 16.1 KB – a saving of 52%), or JPEG-2000 ( 21.0 KB – a saving of 37%) to supported browsers. The first image uses a URL without Cloudinary’s f_auto flag and is therefore delivered in JPEG format across all browsers (while being scaled on-the-fly to 300px width with its aspect ratio retained). The example below displays two sample images. Just add the fetch_format parameter and set its value to auto ( f_auto in URLs). The result is that the best image to deliver to your visitor depends on which browser they are using.Ĭloudinary has the ability to automatically detect which browser is requesting the image and then select the most efficient image format to deliver. Some formats such as AVIF, WebP and JPEG-2000 are more efficient than the standard JPEG format for delivering web images, but they are not supported by all browsers. 10 million pixels means that if you email this image (or multiple photos) to a friend, the photo (which is a lot of space!) will save 30 million bytes (or 30 megabytes).Selecting the Optimal Image Format – f_auto When your camera or cell phone says it takes 10-megapixel photos, it means that each photo has 10 million pixels (megapixels). When an image is large, it can contain millions of pixels, meaning an image can take millions of bytes to store all the information on a computer or device. Usually, 3 bytes (24 one or zero) are used to store each of these pixels. Images are made up of several points called pixels, each of which has a color that is represented as a combination of three primary colors (red, green, and blue).
