Many of us programmers want to hide the file extension of server files such as .php, .jsp, .py etc….
You can easily hide these extensions with the help of a .htaccess file. This feature is only available to Apache servers.
Create a file named .htaccess if your root directory of site doesn’t have one.
Add these lines to the .htaccess file :
<span style="background-color: white; font-family: inherit;"><span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteEngine</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> </span><span class="kw2" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">on</span></span>
<span style="background-color: white; font-family: inherit;"><span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME} !-d</span></span>
<span style="background-color: white; font-family: inherit;"><span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME}.php -f</span></span>
<span style="background-color: white; font-family: inherit;"><span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteRule</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> .* $0.php</span></span>
The above lines wll hide the PHP extension. If you want to hide the HTML and other extension too add these line after
<span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME}.php -f</span>
as you want. You can also replace it if you don’t want php extensions to hide.
HTML
<span class="kw1" style="border: 0px; color: #2060a0; line-height: 18.200000762939453px; margin: 0px; outline: 0px; padding: 0px; vertical-align: baseline; white-space: nowrap;">RewriteCond</span><span style="line-height: 18.200000762939453px; white-space: nowrap;"> %{REQUEST_FILENAME}.html -f</span>JSP

You really should go into each page and delete the extensions, but I believe you can redirect them by adding another rule :
<span style="color: #2060a0;">RewriteRule </span>(.*).<span style="color: red;">html</span> $1 [R=301,NC]
The above rule will redirect all .html pages to non .html extension page.
Replace the red highlighted text with any extension you want to redirect.
