Tools and Tips on how to Optimize Images for the Web

The time a page takes to load is something every designer worries about, or at least is something that every designer should worry about. It doesn’t matter if the layout is nice and beautiful if it doesn’t function properly. Since images can be pretty heavy, this is certainly an issue to keep an eye on. And this is why today we gathered a few links here to show you some tools and articles that will help you with this issue. Even if you are a pro at “saving as better quality jpg” it is always nice to check out some tools (old or new) to have you covered when it is time to optimize images.

    Great little list. I’v always noticed its PNG that tend to be the heavy files on my sites. Some times they just cant be avoided though so some good tools to help with the file size. Iv used Tiny PNGs so will try some others as well.

    If you use a *nix OS, Trimage is a pretty nice equivalent to ImageOptim and worth a mention too. On Ubuntu/Debian:

    sudo apt-get install trimage

    A good trick with 32bit alpha transparent PNGs is to put them through Adobe Fireworks 8-bit alpha transparent PNG filter to see if they can be optimised a fair bit as long as you don’t mind reducing the colour palette down to 256 colours. It’s especially useful for photographic images with a transparent background, where JPEG isn’t an option because of the transparency, and 32bit PNGs offer very poor compression (because they’re meant for block colours).

    Sometimes the effect can be a little ‘grundgy’, and the alpha transparency isn’t always as perfect as 32bit, but still better than 8bit indexed transparency you see on standard 8bit PNG or GIFs. For a few of our sites, its reduced the overall image load on a page from a totally unacceptable 10MB to a more reasonable 200KB.

    It seems that out of all the Adobe software though, only Fireworks does this 8-bit alpha export. File > Image Export > PNG > 8bit Alpha

    Oh, and remember to put them through ImageOptim afterwards to improve the compression even more!

    This is a very important thing for site load times as well. Most people pick the highest resolution images that they can get their hands on and then shrink them without lowering the image file size.

    Nightmare!

    Some of these most basic things seem to be the most forgettable for web designers.

    Simply use Photoshop and use save as for web it will automatically optimize it for web and you have custom setting as well…you can also check the image load time etc.

    these tools can be helpful but i always prefer Photoshop.

    Good overview. I’m sure most people use software on their computer for this but there are some good tools out there to take care of this. I did a video overview of some of the options for optimizing images for speed and size and found imageoptimizer.net to be a pretty useful tool. I explained a couple other options including software and WordPress plugins. Here’s the video I did for those that are interested. http://youtu.be/oi5SCqS-7xw
