|Maximum size of uploaded files (in bytes)
|Introduced in version:||1.8.0 (r16159)|
|Removed in version:||still in use|
|Allowed values:||integer or array (see below)|
|Default value:||1024*1024*100 (100MB)|
|Other settings: Alphabetical | By function|
This setting allows you to place a maximum size on each file that can be uploaded to your wiki.
The value(s) you specify refer to the maximum size, in bytes, of a single file upload (not the total of all uploaded files). The limit is applied at the time of upload, so lowering this value at a later date won't remove existing files that are now 'too large'. This limit only applies to chunked uploads and uploads without separate chunks might have a lower upload limit based on the PHP setting.
There are 1024 bytes in a kilobyte, and 1024 kilobytes in a megabyte, so 1024 * 1024 * 100 = 100 megabytes.
Note: The limits for file uploads are controlled by PHP configuration directives. To change the limits for file uploads, you need to modify php.ini, see the upload_max_filesize and post_max_size PHP configuration options as well as Manual:Configuring_file_uploads for details. Note that whichever one of these php.ini variables is smallest will be the limiter. By default, PHP does not allow uploaded files to be more than 2 megabytes.
Specifying an integer
This limits the maximum size of uploaded files, in bytes, regardless of how they are uploaded.
$wgMaxUploadSize = 20000000;
Specifying an array
If you would like different maximum sizes for file uploads and upload-by-URL, you can set this variable to an array. For example:
$wgMaxUploadSize = array( '*' => 1024 * 1024 * 100, // 100 MB 'url' => 1024 * 1024 * 2, // 2 MB );
This example will set the maximum for all uploads to 100 MB, except for upload-by-URL, which will have a maximum of 2 MB.
To enable upload-by-URL, see
|MediaWiki version:||≤ 1.17|
Note: This option has no effect on the normal upload feature for MediaWiki 1.17 and lower! If you've enabled $wgAllowCopyUploads, this setting does limit the size of files copied from a remote URL as expected. When uploading files from your local machine, this setting has no effect (for at least versions 1.9.3 through 1.12).
