Image file size can disproportionately affect page load time, so it's important to get it right. JPEGs are generally more SEO friendly than PNGs, especially if you don't need transparent backgrounds, as they offer better levels of compression. Computer-generated logos and other Industry Email List high-resolution graphics can usually also use the vector SVG file format (make sure your server also caches, minifies, and compresses this format). The Industry Email List GIF format should be reserved for simple animations that do not require large color scales (they are limited to 256 colors).
For large and long moving images, it may be Industry Email List better to use a true video format instead, as it allows for video sitemaps and the schematic. What matters most is the actual file size (in KB) of the images themselves: Industry Email List always try to save them under 100 KB or less whenever possible. If a larger file size needs to be used above the fold Industry Email List (for hero or banner images for example) it can help to save images as progressive JPGs where images can start to appear gradually as they are
Loaded (a blurry version of the full image first appears and gradually sharpens as more bytes are downloaded). So start by selecting Industry Email List the best format for your needs, then select the best settings for them! Although Google's Lighthouse and PageSpeed Insights audit tools recommend even more specific compression formats (next-gen formats such as JPEG 2000, JPEG XR, and WebP), these are not yet necessarily compatible with Industry Email List all browsers; However, some CDN providers offer WebP conversion when visitors use applicable browsers.
