Limits

What a link can hold, who can open it and how long it lasts.

Visibility

SettingWho can open the link
Public (the default)Anyone with the link.
PasswordAnyone with the link who also knows the visitor password.

A random address is not private. Anyone who is sent the link, or finds it, can open a public link.

A visitor password is 8 to 256 characters. After entering it, a visitor stays unlocked for 12 hours in that browser. Changing or removing the password signs out everyone who had unlocked the link. Password-protected pages are not cached and cannot be read by other websites.

Ask the person you are publishing for which setting they want before you publish. The CLI and API publish publicly unless you set a password.

Expiry and deletion

What happens
Guest linkExpires 24 hours after it was created. Publishing an update does not extend it. After expiry it stops working and cannot be claimed.
Link in an accountDoes not expire. It stays until you delete it.
Claiming a guest linkMoves it into your account at the same address and removes the expiry.
Deleting a linkStops serving it straight away. Its files are cleaned up afterwards. The name is never given out again.
Pruning a versionRemoves one version that is not live. The live version cannot be pruned.

ZIP files count by their unpacked contents: a ZIP that expands past the file, size or storage limits is refused. ZIPs cannot contain other ZIP, 7z or tar archives, and password-protected ZIPs are refused.

Versions that are staged but not yet finalised count towards storage, so an unfinished upload still takes space until it is published or pruned. Unfinished versions are dropped after 24 hours, and a new link that was never finalised is removed after 24 hours too.

DropZoom only serves static files. It does not run server code, so uploaded scripts run only in the visitor's browser. Some names are reserved for DropZoom and cannot be used for a link.
