<p>I would recommend ted, it's the best light weight app I've found for rtf's.</p>

<p>In terms of converting them to html, you might look into DocFrac</p>
<p>I know it can be used from the cli, and offers rtf2html.</p>
<p>Lastly there is a php converter out there called rtf2htm</p>
<p>it's located at <a href="http://freshmeat.net/projects/rtf2htm" rel="nofollow">http://freshmeat.net/projects/rtf2htm</a></p>
<p>It doesn't look like it has been developed recently, but it worked when I looked into it.</p>
