Review website compression settings

Understand the Optimize Website options before changing response compression.

Where Tools → Software → Optimize Website

Before you start

  • Record the existing setting and ask support which compression layer serves your site.
  • A CDN, LiteSpeed or the application may already handle compression.

Steps

  1. 1

    Open Optimize Website and review the current Compress Content setting.

  2. 2

    Disabled leaves this particular cPanel compression setting off; it does not prove every other compression layer is disabled.

  3. 3

    Compress All Content applies broadly. Compress the specified MIME types limits this setting to the listed content types. Choose the scope appropriate for the site.

  4. 4

    Click Update Settings only when ready, then test page responses and downloads. If behaviour changes unexpectedly, restore the recorded setting and ask support about the server’s compression configuration.

  5. 5

    If using specified types, review the MIME Types field carefully. Do not enter file extensions where content types such as text/html are expected.

    Choose the compression scope, then use Update Settings.

Check it worked

  • Check representative page and asset responses with a suitable diagnostic tool or support.
  • The website and downloadable files still load correctly.
