Custom upload adapter

There are several reasons why developers choose to implement custom upload adapters in CKEditor 5. These may include server integration requirements (dependent on the existing architecture where the editor is deployed), local security and authentication rules, or business logic.

The CKEditor 5 Framework offers an open API with a set of classes for upload adapters that handle the entire upload process from when a user adds a file (for example, by dragging an image) to when the server responds, acting as a bridge between the editor and your server.

Check out this dedicated Custom Upload Adapter guide, which explains how to create custom file upload functionality for the editor.
