Hide Text tool protects your text to be found by search engine spiders by converting text to image. Did you know every time you post text online it gets spidered and stored in various caches, including Google, Alexa Wayback machine and more. For example you selling a site on a popular forum, typing an URL in plain text format will mean the future buyer will have to live with people seeing the topic he brought the site from... less than ideal!
Or another example is if you've ever popped your email online, no doubt it's got spammed as a result, spiders cannot understand pictures as well meaning you won't get hardly as much spam! Simply put it's free to do, and could help you out more than you would know!.
