# File Upload

The `File Upload` field allows users to upload a single or multiple files.

You can also configure the type of files allowed to be uploaded (e.g. documents, media, etc.) and specify a max file upload size as well.

If no max file size is specified, the field will have a default size constraint of 10MB, and at most 20 files can be uploaded to a single field. These constraints can be increased on the business plan.
