I have enabled GZIP in cPanel (Software > Optimize Website). It's set to "Compress All Content". GTmetrix speed test reports that one CSS file is not being compressed:
https://www.swphotovideo.com.au/wp-content/cache/min/1/2affb9ab843ac1d569fdadbf67636031.css
Any idea why this might? It's quite large (1mb~) so I'd like to sort it out. GZIP seems to be working for everything else, but this file.
We use GZIP to compress files so that Websites speed will become fast. As your problem shows you are able to compress all other files but not able to compress "CSS" files.
First of all, you should check your .htaccess file and check whether "TEXT/CSS" is there under "mod_deflate" or not.
# BEGIN GZIP
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</ifmodule>
# END GZIP
Also, to speed up your WordPress website you can use mod_expires to have Browser cache in WordPress which will speed up your website.
You can refer this article to speed up your WordPress application.
https://hoststud.com/resources/tips-to-leverage-browser-caching-in-wordpress.156/
Or, you should ask your hosting provider regarding this issue.
I have added the following code in my .htaccess file:
<ifmodule mod_deflate.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml text/css application/x-javascript application/javascript
</ifmodule>
However, I have one URL "http://www.example.com/foo/" that doesn't behave well when gzipped.
This is for a wordpress site, so the /foo/ isn't a real folder/directory -- it's just the permalink slug. I've found the following code to exclude folders but I can't get it to work and I think it's because /foo/ is not an actual directory?
SetEnvIf request_uri ^/foo(.*) no-gzip dont-vary
Is there a way to exclude any URL that contains /foo/* from being deflated?
Thank you!
I Was using google page speed insights and it recommended my css pages to be compressed.So I added this htaccess
<filesMatch "\.(js|css)$">
Header set Content-Encoding x-deflate
# Header set Content-Encoding compress
# Header set Content-Encoding x-gzip
</filesMatch>
So It was compressing css and working fine in chrome , But in firefox When I access http://fasttorrent.me/cdn/bootstrap.css css link it was blank and I get below error
The character encoding of the plain text document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the file needs to be declared in the transfer protocol or file needs to use a byte order mark as an encoding signature.
So I added below code
<filesMatch "\.css$">
FileETag None
<ifModule mod_headers.c>
Header set Content-type "text/css"
</ifModule>
</filesMatch>
But still I get same error in firefox and iphone safari.
EDIT : I tried to set charset like below..still error
<filesMatch "\.(html|css|js)$">
AddDefaultCharset UTF-8
DefaultLanguage en-US
Header set Content-Encoding x-deflate
</filesMatch>
I was having a similar problem earlier and it looks like firefox doesn't support the following lines because they are declaring that the output is compressed but not actually compressing it. https://support.mozilla.org/en-US/questions/1063554
<filesMatch "\.(js|css)$">
Header set Content-Encoding x-deflate
# Header set Content-Encoding compress
# Header set Content-Encoding x-gzip
</filesMatch>
So as per this link https://varvy.com/pagespeed/enable-compression.html I replaced it with the following and now all seems to be working.
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
Goal
I'm new to the world of compression.
I would like to enable the gzip compression for my website.I'm not sure how will accomplish that the right way.
I've tried
create .htaccess in the root/ directory of my site and add these lines :
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/xml
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/x-javascript
Test using cURL
I tried run curl -I -H 'Accept-Encoding: gzip,deflate' http://my-site.com
Result :
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
0 20 0 0 0 0 0 0 --:--:-- 0:00:30 --:--:-- 0
Content-Encoding: gzip
Note : Content-Encoding: gzip
Test using GZip Testing Online Tool
I go this site and enter my URL.
http://checkgzipcompression.com/?url=http%3A%2F%2Fwww.bunlongheng.com%2F
Result : You're blessed! It's GZIP Enabled.
I also test on : https://www.feedthebot.com/tools/gzip/
Result : Gzip working? Yes reducing file size by 71.6%
Browsers
I've tried on : Safari, Firefox, and Chrome.
After passing 2 tests, I thought, I did it correctly, but when I go to my site : My styles all screw up. Feel free to see it : here
My console keep giving me this error :
Failed to load resource: net::ERR_CONTENT_DECODING_FAILED
Can someone please explain why is this happening ?
Do I need to configure anything in my php.ini ?
If so, I might need to create one because I don't have that.
Any helps will be really appreciated.
I'm gonna suppose that you are using an Apache Web Server. You have to add into your .htaccess these lines:
<ifModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file .(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text/.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image/.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</ifModule>
To check if GZip is enabled you can use this tool:
https://www.feedthebot.com/tools/gzip/
YSlow is telling me that my css should be compressed, but after several hours of tinkering, I cannot for the life of me get gzip to work for my website. At this point, I'm not even sure if the performance increase (will there be one?) will be worth the effort.
I'm running a WordPress site on a 1&1 shared hosting account.
Honestly, I don't really know what I'm doing with this stuff, and can't seem to get an appropriate setup. I read in a few places that with 1&1, "modules Apache mod_deflate and mod_gzip are not installed.", so I assume this is part of the problem.
I have tried the following code:
This one doesn't seem to do anything:
<IfModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_dechunk Yes
mod_gzip_item_include file \.(html?|txt|css|js|php|pl)$
mod_gzip_item_include handler ^cgi-script$
mod_gzip_item_include mime ^text\.*
mod_gzip_item_include mime ^application/x-javascript.*
mod_gzip_item_exclude mime ^image\.*
mod_gzip_item_exclude rspheader ^Content-Encoding:.*gzip.*
</IfModule>
This causes a 500 error

I followed the tutorial found here
(http://mrrena.blogspot.com/2009/01/how-to-compress-php-and-other-text.html)
but this essentially completely broke the appearance of my site.
Tried this in my Functions.php, and it seemed to compress my html, but leaves some js and css uncompressed
if(extension_loaded("zlib") && (ini_get("output_handler") != "ob_gzhandler"))
add_action('wp', create_function('', '#ob_end_clean();#ini_set("zlib.output_compression", 1);'));
So, after a while I figured out how to compress html, css and js files having a 1&1 Webhosting package. Deflate is not supported!
For the dynamic content you add php.ini to your root directory of your website. Content of php.ini:
zlib.output_compression =1
zlib.output_compression_level =9
Of course you can also choose another compression level, 9 is the highest (and causing the highest server load). That will compress your the dynamically generated html file.
To compress static files (css, js and images...) you need to modify the .htaccess file. For that append
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteBase /
RewriteOptions Inherit
ReWriteCond %{HTTP:accept-encoding} (gzip.*)
ReWriteCond %{REQUEST_FILENAME} !.+\.gz$
RewriteCond %{REQUEST_FILENAME}.gz -f
RewriteRule (.+) $1.gz [QSA,L]
</IfModule>
to your .htaccess file (you find that file in the root directory of your website - else create it).
But the compression is not done automatically. So you have to compress the files on your own! Use e.g. 7-zip and compress the js and css files with .gz -> the result should be e.g. stylesheet.css.gz.
Then upload the file to the same directory as the file you just compressed.
Now it should work!
PS: compression is not always useful especially when the file is very small. So check the differences before and after compression.
It looks to me like you have exhausted your option. Looking at the above it seems like the host indeed doesn't have mod_deflate or mod_gzip. So I guess you are just out of luck.
The PHP solution is indeed only for the HTML. So just stick with that one. HTML is also the best place to add compression, as, most of the time, the CSS and JS are only downloaded on the first page.
You could redirect the request to CSS and JS though a PHP script, and use the PHP to compress. But I would not go there, as you would also have to implement 304 Not modified and set the appropriate expires headers.
Enable gzip compression
The gzip compression can be activated in php.ini with the following code:
zlib.output_compression = On
zlib.output_compression_level = 9
allow_url_fopen = On
I know this question is a bit old now, but I've found a solution that works for me.
Add a file called "php.ini" to the root folder containing the following;
zlib.output_compression = On
zlib.output_compression_level = 9
Then (and this is the bit you might not expect) add the following to your .htaccess file;
AddType x-mapp-php6 .html .htm .php
Yes, that's right. I've put php6 in that. Apparently that will run the latest stable version of PHP (currently 5.4) which will allow gzip compression. This will also run .html and .htm files through the PHP parser, which means that they can be compressed (files not run through the PHP parser will not be compressed). Feel free to add any other extensions that you want to be run through PHP (.xml for example).
By the way, if you do run .xml files through PHP, remember to set the header declaring it as an xml file, otherwise it won't work properly.
Hope this helps!
Works for me,
First you have to copy the php.ini in all directory.
(1and1 provided a script to facilitate this manipulation in their faq)
with this content :
zlib.output_compression =1
zlib.output_compression_level =9
Then add this in the htaccess :
<IfModule mod_gzip.c>
mod_gzip_on Yes
mod_gzip_item_exclude file \.(gz|zip|xsl)$
mod_gzip_item_include mime ^text/html$
mod_gzip_item_include mime ^text/plain$
mod_gzip_item_include mime ^image/x-icon$
mod_gzip_item_include mime ^httpd/unix-directory$
mod_gzip_item_include mime ^text/javascript$
mod_gzip_item_include mime ^application/javascript$
mod_gzip_item_include mime ^application/x-javascript$
mod_gzip_item_include mime ^text/x-js$
mod_gzip_item_include mime ^text/ecmascript$
mod_gzip_item_include mime ^application/ecmascript$
mod_gzip_item_include mime ^text/vbscript$
mod_gzip_item_include mime ^text/fluffscript$
mod_gzip_item_include mime ^text/css$
</IfModule>
You can enable compression by adding this code into your .htaccess file :
<IfModule mod_rewrite.c>
AddOutputFilterByType DEFLATE text/text text/html text/plain text/xml image/svg+xml image/x-icon text/css application/x-javascript application/javascript application/x-httpd-php application/x-httpd-fastphp application/x-httpd-eruby
</IfModule>
