Increase the Maximum File Upload Size in WordPress

In most situations there is a need to upload bigger file to WordPress site, and by default there is a limit of file size for uploading. Below are few options to increase file size which can be uploaded to WordPress.

Theme Functions File
There are cases where we have seen that just by adding the following code in the theme function’s file, you can increase the upload size:

@ini_set( 'upload_max_size' , '64M' );
@ini_set( 'post_max_size', '64M');
@ini_set( 'max_execution_time', '300' );

Create or Edit an existing PHP.INI file
In most cases if you are on a shared host, you will not see a php.ini file in your directory. If you do not see one, then create a file called php.ini and upload it in the root folder. In that file add the following code:

upload_max_filesize = 64M
post_max_size = 64M
max_execution_time = 300

htaccess Method
Some people have tried using the htaccess method where by modifying the .htaccess file in the root directory, you can increase the maximum upload size in WordPress. Open or create the .htaccess file in the root folder and add the following code:

php_value upload_max_filesize 64M
php_value post_max_size 64M
php_value max_execution_time 300
php_value max_input_time 300
