WordPress Theme users, let’s remove “Proudly powered by WordPress” from the footer of your website. It’s pretty simple. A line of CSS would do the job.

Remove “Proudly powered by WordPress” on Twenty Sixteen, Twenty Seventeen, Twenty Nineteen, Twenty Twenty-One Theme

Open Up the CSS Editor:
(Go to the Backend page -> Appearance -> Editor)

footer .site-info { 
 display: none !important; 
}
footer.site-footer:after {
 content: "© YOUR WEBSITE NAME";
}

Replace YOUR WEBSITE NAME as you like.

footer.site-footer:after {
 content: "© YOUR WEBSITE NAME";
 margin: auto;
}

If you want to center align the Copyright line, add margin:auto like below:

Remove “Powered by WordPress” on Twenty Twenty Theme

Open Up the CSS Editor:
(Go to the Backend page -> Appearance -> Editor)

.powered-by-wordpress {
    display: none;
}

Remove “Proudly Powered by WordPress” on Twenty Twenty-Two Theme

Open Up the CSS Editor:
(Go to the Backend page -> Appearance -> Editor)

.has-text-align-right {
    display: none;
}

Now it’s all good!
