Settings, every option explained

Settings live under Offloft → Settings and save automatically. The defaults suit most sites, and you can leave anything in Advanced alone unless support asks. Number settings stay within an allowed range, and each one notes when it only applies to files offloaded from then on.

Connection

Your provider, keys, bucket and any region or endpoint. See connect a provider.

Delivery

Setting	Default	What it does
Delivery domain	None	The address visitors load your media from. Images switch only after they load from it.
Force HTTPS	Off	Always serve media over a secure connection.
Rewrite media URLs	On	The master switch. Turning it off serves everything from your server again.
Versioned file paths	On	Adds a short version to each address, so browsers never show a stale copy.
Cache lifetime	1 year	How long browsers and CDNs may keep a copy. Without versioned paths, 1 day at most.

Uploads & sync

Setting	Default	What it does
Offload new uploads automatically	On	New media goes up a moment after WordPress finishes creating its sizes.
File types to skip	None	Types to leave on your server, such as application/zip or video/*.
Path in bucket	wp-content/uploads/	Where files go inside your bucket.
Quiet period	30 seconds	Wait this long before uploading, so other plugins can finish editing. 5 to 3,600.
Delete from the cloud when deleted in the Media Library	On	Keeps your bucket tidy.
