Let Community Guest Users Upload Files

Promote file sharing in your communities. Let guest users upload files using the lightning:fileUpload component.

Where: This change applies to Lightning Experience in Contact Manager, Group, Professional, Enterprise, Performance, Unlimited, and Developer editions.

How: By default, guest user files are blocked from being uploaded. Once developer customizations (Lightning pages, for instance) have been created, admins can change the settings to let guest users upload files. To enable, go to Setup > General Settings, and select Allow site guest users to upload files.

Allow guest users to upload files



By default, unassigned files are public. As a best practice, set up a trigger to assign an owner to files uploaded by guest users. You may also wish to restrict file upload size or type using community file moderation.
