WordPress post revision can be helpful for blogger or website owner to compare the previous changes of posts with the newer one.

Limit WordPress Revisions

By default WordPress stores every revision of posts into the database. You can limit it by adding the following code to your wp-config.php file.

By adding the below code, WordPress will store all the revisions of posts.

wp-config.php
define( 'WP_POST_REVISIONS', true);

To limit the post revisions, you need to the add:

wp-config.php
define( 'WP_POST_REVISIONS', 4);

Now WordPress will store only 4 revisions of the post into the database. And to disable the post revisions, your code will be:

wp-config.php
define( 'WP_POST_REVISIONS', false);

true (default), -1: store every revision.

false, 0: do not store any revisions (except the one autosave per post).

(int) > 0: store that many revisions (+1 autosave) per post. Old revisions are automatically deleted.

To delete the revisions form the database, you can use the following query:

DELETE FROM wp_posts WHERE post_type = "revision";</code

Hope it will help to make your website faster. Thank You 🙂
