# Upload Large Files To SharinPix

## Overview

In this article, we will demonstrate how to use a multipart image upload on a SharinPix Album or SharinPix Single Image. To do so, we will:

* [Create a SharinPix Permission to set Multipart Upload](#creation-of-sharinpix-permission)
* [Assign the Permission to a SharinPix Component](#assign-the-sharinpix-permission-to-the-album-component)

SharinPix uses a feature called **Multipart Upload** for large file transfers: breaking a large file into smaller parts, uploading them in parallel for speed, and reassembling them in Amazon S3.

The key benefits include:

* Improved Throughput/Speed when uploading large files
* Enhanced Reliability and Fault Tolerance
* Efficient Memory Usage

**Note:** 

* If you do not frequently upload files larger than **100 MB**, do not activate this, as it will affect performance
* **Before using this feature, ensure you have the latest SharinPix package installed.** [*How to upgrade SharinPix package*](https://app.gitbook.com/s/i8tH1o5AHthxksYgF6ij/how-to-update-sharinpix-package-from-the-appexchange)

## Creation of SharinPix Permission

* In [SharinPix Permissions](https://docs.sharinpix.com/documentation/access-and-security/sharinpix-permission-object-how-to-create-and-assign-custom-permission), create a new record or edit an existing permission.
* Open the Upload section and check Multipart Upload.

## Assign the SharinPix Permission to the Album component

* On a [SharinPix Album](https://docs.sharinpix.com/documentation/lightning-web-component/sharinpix-album-lwc), add the **ID** or **Name** of the SharinPix Permission record, which includes the maximum file size.
* In this example, the custom permission was named **Upload Multipart**. It has been set in the **Custom Permissions ID or Name** parameter of a *SharinPix Album* component.

**Tip:**\

The above will also work for a [SharinPix Single Image](https://docs.sharinpix.com/documentation/lightning-web-component/sharinpix-single-image). The custom permission created should then be defined as a Single Image Permission.
