![]() CSS3 effects and animations along with web fonts can sometimes be used to produce resolution-independent resources at a fraction of the size of the corresponding image.Using vectors for geometric graphics, enables sharp results at every resolution and zoom, with a minimal file size. Vector graphics (SVG) are based on line, point, and shape markup, rather than pixels.You can also consider delivering lossy animated GIFs to get a smaller file when image quality is not a top priority. Instead of large animated GIFs, deliver animated WebP or use JPEG-XR (with CSS Animations (using the step property) to supported browsers, or convert to an MP4.Take advantage of CDN services or other tools/logic to check which browser is making the request and deliver different formats for different browsers using the element and its srcset attribute.Make sure each image is delivered in the right format for its image content.These types of images don’t look good in lossy formats, but delivering them as PNGs results in a large cumulative size for these images, which can slow your page load time. Small images, like buttons and logos are often a larger percentage of site images than designers realize and many appear on every page.Delivering the standard formats for all browsers misses out on valuable savings from newer formats like AVIF and WebP. Different browsers support a variety of formats that may be more efficient than the standard JPG, PNG, and GIF formats.Lossy formats work quite well for some image content, but not for others. Some image formats are also lossy, meaning they discard some pixel data. All image formats use some form of image compression.When it’s important to deliver top-quality images for high-res devices, use the element and its srcset attribute to deliver different resolutions for different devices. ![]() Consider your image purpose and audience, and use the lowest possible quality that is acceptable for the image content, audience, and purpose. In most cases, you can significantly lower quality without a significant visual impact. The result is a huge file and slow delivery speeds. Often photographs are delivered at their original extra-high resolution, for fear of losing too much visual quality or to make sure users with high-res (retina display and DPR 2+) devices will get the quality they expect. Click the link on each issue to learn how to use Cloudinary functionality to implement these solutions with minimal or no coding. However, in many cases, implementing the solutions on your own can be very time or labor intensive. The following table summarizes the main elements that impact image file size and potential solutions for addressing those issues. Optimizing an image involves delivering images in the format, dimensions, resolution, and quality that will yield the smallest possible file size while ensuring that the resulting image is appropriate for the specific content, the overall page design, the requesting device, and the expectations of your site visitors. ![]() User-defined variables and arithmetic transformations.
