Check and Enable GZIP compression

Description

GZIP compression is bundling (zipping) pages on a web server before the page is sent to the visitor.
This saves bandwidth and therefore increases the loading speed of the page significantly.
The visitors’ web browser then automatically unzips the pages. This compressing and unzipping only takes a fraction of a second.

This plugin checks if your WordPress site has GZIP compression enabled. Every time you run this check, your domain name will be sent to http://checkgzipcompression.com. We won’t sent any other private information.

Screenshots

  • When enabled the plugin will tell you if GZIP is enabled.
  • The detail page will show you details about the GZIP compression state. And will make it possible to enable GZIP compression.

What is GZIP compression?

GZIP compression is bundling (zipping) pages on a web server before the page is sent to the visitor.
This saves bandwidth and therefore increases the loading speed of the page significantly.
The visitors’ web browser then automatically unzips the pages. This compressing and unzipping only takes a fraction of a second.

GZIP compression is recommended for all types of text files such as:
– HTML (.html) but also all types of dynamic HTML (such as extension .php, .aspx)
– Textfiles (extension .txt)
– CSS and Javascript (extensie .css and .js)
– Webservices, such as WSDL, REST and JSON

GZIP compression is not recommended for non-text files, such as graphical files and .zip files because it hardly saves space and can therefore increase the loading time.

Why is GZIP compression important?

GZIP compression saves 50% to 80% bandwidth and will therefore significantly increase the website’s loading speed.
The textfiles are compressed (zipped) on the web server after which the visitor’s web browser will automatically unzip the files. This compressing and unzipping only takes a fraction of a second without the end user noticing.

Just about all the large websites worldwide use GZIP compression. For and actual overview of GZIP usage nowadays please check our statistics page.

Intermittent success

I’ve used it on a few sites – would love to put it on all my clients’ sites, but often it fails to connect to checkgzipcompression.com
This is the message I get:
Oops! Something went wrong 🙁 It could be that you are on a local development environment, or that we couldn’t contact checkgzipcompression.com

We checked the url: [link removed]

This is a live site – would love to get this working. Any ideas?

It works

Gzip compression stopped working in my site despite it was enabled in CPanel settings. This plugin made it work again. Thanks.

Disable GZIP Compression ”

Makes admin panel extremely slow

Since a couple of weeks I was struggling with an extremely slow and almost non reactive admin panel. I thought that after some updates the problem would solve by itself but it didn’t.

Today I started to deactivate all the plugins and when deactivating GZIP my admin panel started to respond fast again.

I will keep deactivated the plugin until next update.

Site crashed. It took me an hour to restore it.

Installed the plugin, activated and all my site went down. This should NOT happen when it says it’s compatible with the version of wordpress I have. I have not a special installation. I have a basic wordpress installation.

It sucked. I had to skip lunch. Now I am angry and hungry.

Don't use this plugin, it will break your site

I installed this plugin this evening. After I activated and selected “Enable GZIP compression”, then the disaster came! My site completely down, I even can’t login to WordPress! I called my hosting customer support, and it took them at least half an hour try to find the problem – but they can’t even figure out why this happened! So I have to restore my backup, unfortunately I forgot the backup my site since two month ago. Now my site is back, but it is two months old, I lost all of my updates. I am very unhappy with this plugin, please stay away from it if you don’t want trouble!
