Using Online Image Optimization Tools with WordPress
Web images must be optimized, or compressed, to keep website load times down. For WordPress websites, online images can be optimized using image-editing software programs that compress the files as much as possible without losing image quality. If such image-editing software is not available, you can compress them using online image optimization tools.
Here are a few nifty, free, online, image optimization tools that you, and your clients, can use:
Dynamic Drive: This tool lets you input the web address of the image you want to compress or upload an image from your computer. The image optimizer lets you choose what type of image you want to output — PNG, GIF, or JPG — or you can choose all three.
After this tool gives you the optimized, compressed images, you can save them to your local computer (usually by right-clicking the images and choosing Save Image As) to use on your website later.
Yahoo! Smush.it: This tool lets you upload an image from your computer or enter the URL of the image, and it optimizes and compresses the image to make it available for you to download. Smush.it also reports on the results of the image compression by telling you, in percentages, how much it was able to smush, or compress, your image.
Image Optimizer: Image Optimizer is another free online service that compresses and resizes your images, and then provides them in a downloadable format for you to use on your website pages.
Image Optimizer is also available as an application that you can download to your computer so you can use it locally, rather than using the Image Optimizer website to compress your images.
Web Resizer: The Web Resizer tool does the same as the previous tools, allowing you to upload an image that it compresses and then makes available for download to your computer. This tool also provides other image-editing tools like resizing, cropping, adding borders, and changing the tint and contrast of the image.
