Hey guys, today in this post we are going to learn about How to creates a custom file uploader component that allows multiple files of JPG, PNG, PDF to be upload in object Uses of ‘lightning-file-upload’ elements in Salesforce Lightning Web Component — LWC .

A lightning-file-upload component provides an easy and integrated way for users to upload multiple files. You can configure the file uploader to accept specific file types, and the file types are filtered in the user’s file browser. To upload files using lightning-file-upload, you can:

  • Select a file on your system by clicking the button to open the system’s file browser
  • Drag a file from your system into the file selector dropzone

To associate an uploaded file to a record, specify the record-id attribute. Uploaded files are available in Files Home under the Owned by Me filter and on the record’s Attachments related list that’s on the record detail page. If you don’t specify the record-id attribute, the file is private to the uploading user.

Although all file formats that are supported by Salesforce are allowed, you can restrict the file formats using the accept attribute.

The button label is “Upload Files” by default. Use the label attribute to add a descriptive label above the Upload Files button.
