How to Optimize Images: Bitmapped Graphics and Resizing

Tired of slow loading times because of large images? Optimize images is your solution. This guide covers how to modify and resize graphics and rasterized images while maintaining image quality and file size.

Bitmapped (or Rasterized) Graphics

When you make a copy of any graphic or image, try using the original to make that new version so you retain as much of the quality as possible. Always check that your image mode is on RGB color.

Every time you shrink the picture with a graphics package, it degrades to use fewer colors, and the quality decreases. If you use the original, you will always get the best number of colors available. Unless it's a vector, you cannot produce a high-quality, bigger version because there won't be enough color to render the picture the same quality.

Take note: Once the graphics package-for example, Adobe Photoshop or Adobe Fireworks-has optimized the graphic, you cannot get back to the original quality. GIFs are indexed in color, and JPGs may reduce their quality to shrink the file size.

There will always be a trade-off between quality and file size. Opting for a smaller file size will result in faster download times.

Resizing Images on a Web Page

Do not use the width and height attributes of the <img> tag in the HTML code of a web page to resize images. This will consequently increase the browser's time to download the page, as it will now "redraw" the image to an incorrect size, thus taking longer.

Avoid scaling an image because this technique severely lowers the quality and lengthens the loading time. Resize your images properly in your favorite graphics software, and add width and height dimensions for faster downloads. You'll end up with a more attractive website and higher downloading speeds.

Some free online tools to compress and resize images include Kraken.io and Optimizilla.
