Large images are the leading cause of slow loading Web pages. GIFBot can optimize your images by up to 90% without loss of image quality. Here's how:

Step 1: Enter the URL of your image.

Step 2: Select the format of the image you want GIFBot to generate. In most cases you will want the output image to be the same as the imput type.

Step 3: Press "Optimize" to start your job.

GIFBot will then generate different versions of your image with progressively less colors (or higher compression ratio). You can then select the image which has the best combination of image quality and file size.

GIFBot's unique "mouse over" feature can help you spot minor differences in image quality. Just move your mouse over the optimized image to see the original image. Click on the image to save it to your computer.

GIFBot works on both GIF and JPEG file. It can process transparent GIFs and GIF animations.

Tip: Enter the URL of a Web page and GIFBot will index all the images on that page. Click on each image's file size on the results page to optimize that image.

Images with large areas on a single color are best saved in GIF format. GIF images may also have animation and transparency. If the original image is a GIF, these attributes will be preserved in the reduced images.

Images with continuously varying tones may benefit from being converted to JPEG format. Scanned images and photographs best fit this category.
