Will it be convenient for the recruiters if I attach a single file web page, while sending job search emails?

File attachments other than your CV and a cover letter are not recommended unless you are asked for it.
If you mean single file webpage with your CV and more details on it, I won't hesitate to put a link to that web page alongside my contact details on CV and cover letter.
But if you mean to show just your work skills (in case of graphic designers etc) than my answer may change slightly.
