Optimizing sprites for the web

From: Illustrator for Web Design

Video: Optimizing sprites for the web

Once you have all of your images loaded into your sprite grid here inside of Illustrator, it's time to take them and export them out for use in an HTML/CSS editor, and to display them on the web. So the first thing we need to do is go to the File menu and choose Save for Web. Once we have that done, we need to pick the best type of export for our icons or whatever it is that we might be exporting. Now, this is going to be dependent on exactly what type of graphics you've created. In this case I've a lot of flat areas of color and I don't have any transparency, so I think the best thing to do here would either be a GIF or a PNG.

Optimizing sprites for the web

Once you have all of your images loaded into your sprite grid here inside of Illustrator, it's time to take them and export them out for use in an HTML/CSS editor, and to display them on the web. So the first thing we need to do is go to the File menu and choose Save for Web. Once we have that done, we need to pick the best type of export for our icons or whatever it is that we might be exporting. Now, this is going to be dependent on exactly what type of graphics you've created. In this case I've a lot of flat areas of color and I don't have any transparency, so I think the best thing to do here would either be a GIF or a PNG.

So in this case I think maybe PNG would serve me well. PNG-24 might actually be the best, in terms of quality, but it's also going to be a higher file size. But in this case these are so small, 4.5k, it's not that big of a deal. And so once I pick this, I'll go ahead and hit Save, and I'll go out to my desktop and I'll just save this out as social_icons, and hit Save. Once I do that, I now have a PNG graphic saved out to my desktop which I could then hand off to my developer, and they could use that, along with some creative positioning techniques via CSS, to display these individual icons anywhere that they need to on my web site, but they would all load instantly in the background because they're all a part of this one single image sprite.

If you would like more information about how to optimize your graphics for the web, including all types of web graphics with transparency, photographs, et cetera, you want to go back and watch chapter 10 of this course, because that's where I cover all of the optimizing web graphics and how to get your things out of Illustrator at the highest quality for the smallest file size possible.
