It checks your web pages for broken links and dangling tags and optimizes both web pages and graphic files. The program offers 5 functions plus a number of useful options that make working with HTML-Optimizer very easy. Especially the new 'Duplimize' option comes in handy - see the manual in the program. Though this may seem a small improvement, load time savings is much higher as your client's browser parses the pages more efficient. Embedded script code, e.g. JavaScript, is not ruined.
Resources are of no use on the web.
Another function of HTML-Optimizer is to check the tagged pair structure of your web pages. Any dangling tag will be reported. If you choose the extensive mode, IMG tags are checked for the presence of the Width, Height and Alt attributes. The Width and Height attributes are needed by the browser to build up the page as fast as possible. At the Preferences you can choose to add missing Width and Height attributes with pixel values which are automatically derived from the image concerned.
