Ever think that the WordPress maximum upload file size is small?
How to know the maximum upload file size?
From the dashboard, go to Media > Add New
The maximum upload size depends on the server settings, if you want to tweak it, here are a few ways to do it.
functions.php
@ini_set( 'max_execution_time', '300' );
@ini_set( 'upload_max_filesize' , '128M' );
@ini_set( 'post_max_size', '256M');
@ini_set( 'memory_limit', '128M');
php.ini
max_execution_time = 300
upload_max_filesize = 128M
post_max_size = 256M
memory_limit = 128M
.htaccess
php_value max_execution_time 300
php_value upload_max_filesize 128M
php_value post_max_size 256M
php_value memory_limit 128M
wp-config.php
@ini_set( 'max_execution_time', '300' );
@ini_set( 'upload_max_filesize' , '128M' );
@ini_set( 'post_max_size', '256M');
@ini_set( 'memory_limit', '128M');
If you don’t have access to any of those, then add the Increase Maximum Upload File Size plugin.
Please take note that the maximum upload size also depends on the server settings, if these do not work, contact your host.
