--- category: features-image-upload menu-title: Base64 upload adapter order: 40 --- # Base64 image upload adapter The {@link module:upload/adapters/base64uploadadapter~Base64UploadAdapter Base64 image upload adapter} plugin converts images inserted into the rich-text editor into [Base64-encoded strings](https://en.wikipedia.org/wiki/Base64) in the {@link builds/guides/integration/saving-data editor output}. This kind of image upload does not require any server-side processing — images are stored with the rest of the text and displayed by the web browser without additional requests. On the downside, this approach can bloat your database with very long data strings which, in theory, could have a negative impact on the performance.
