This online tool will take HTML code (either a full web page or a snippet of HTML) and convert it to plain text. This tool will automatically remove all HTML tags. It also displays the title and description meta tag information if present
It should work perfectly fine unless you have a less than or greater than sign in your text content then things might go haywire. Because HTML tags also use these symbols, they may, if present in the content, cause unexpected conversion problems.
If you do run into problems then my recommendation is to remove any less than or greater than sign that occurs in your text content before converting to plain text.
If you just want to get the text content from a page in order to edit the revise the content than this could be a very useful tool for you.
