You can increase the upload limit to your Wordpress installation by adding (or amending) a php.ini to the wp-admin folder with the following settings:
post_max_size = 150M upload_max_filesize = 100M
The php.ini settings are non-recursive (i.e., only apply to that folder and not its children).
Adjust as needed by making the settings larger than the file you're uploading.
You can see this process in the video below.
If you're still having difficulty uploading after changing the settings above, or you get an error saying "413 request entity too large", you may need to configure one additional setting on your server.
- Apache: Set the LimitRequestBody directive in either your httpd.conf file or a local .htaccess file. (https://stackoverflow.com/a/3719358/1688568)
- Nginx: Set the client_max_body_size directive in nginx.conf (http://www.cyberciti.biz/faq/linux-unix-bsd-nginx-413-request-entity-too-large/
