Best Angular File Upload Libraries Compared

The short answer: for an Angular uploader that sends files straight to your own S3-compatible bucket, with cloud drives and resumable uploads, use upup or Uppy. If your app already uses PrimeNG, its FileUpload component is the smallest step. ngx-file-drop only handles the drop zone, and FilePond gives you one polished component that posts to your server.

This roundup compares five Angular file upload libraries on the features that usually decide the choice, then explains how to pick.

Comparison table

The libraries

upup

upup's @useupup/angular is a native Angular port of its uploader: a standalone component with a single config input, built on the same headless core as every other upup package. It uploads directly to S3-compatible storage with presigned URLs, either from your own signing endpoint or through @useupup/server, and lets users pick files from the device, Google Drive, OneDrive, Dropbox, Box, a camera, a screen capture or a link. The built-in image editor is available in the React and Preact packages only, not in Angular. See the Angular file uploader page for a three-step setup.

ngx-file-drop

ngx-file-drop is a drop-zone component that accepts dropped files and folders and hands them to your code. It does not upload anything, so you add the HTTP requests, progress and storage yourself. It is a good fit when you only need the drop target.

PrimeNG FileUpload

FileUpload is one component in the PrimeNG suite. It offers a basic button mode and an advanced mode with a drop zone, file list and progress bar, and it posts to a URL you give it or hands the files to your own upload handler. It's the natural choice if PrimeNG is already your component library.

FilePond

FilePond is a single animated upload component with an Angular adapter. It posts files to your own server endpoint, supports chunked uploads, and extends through plugins for previews, validation and image transforms. See upup vs FilePond.

Uppy

Uppy is a modular uploader with Angular components. Plugins cover the Dashboard UI, sources (webcam, screen capture, remote drives through Companion, a server you host) and destinations such as tus and S3. See upup vs Uppy.

How to choose

• You want a finished uploader on your own bucket: upup or Uppy.
• Your users pick files from Google Drive, OneDrive, Dropbox or Box: upup or Uppy. Uppy routes remote files through Companion; upup does it in the browser (client mode) or in @useupup/server (server mode).
• You already use PrimeNG: start with PrimeNG FileUpload and switch only if you need S3, cloud drives or resumable uploads.
• You only need a drop target: ngx-file-drop, then write the upload code.
• You need image editing in Angular: Uppy's Image Editor plugin, or FilePond's plugins. upup's editor is not available in Angular.
• You upload very large files: use resumable uploads, with upup or Uppy.

Minimal upup example

Install the package:

npm i @useupup/angular

Add the standalone component and point it at an endpoint that returns a presigned URL:

import { Component } from '@angular/core'
import { UpupUploaderComponent } from '@useupup/angular'

@Component({
    selector: 'app-root',
    standalone: true,
    imports: [UpupUploaderComponent],
    template: `<upup-uploader
        [config]="{ provider: 'aws', uploadEndpoint: '/api/upload-token' }"
    />`,
})
export class AppComponent {}

Load the stylesheet once globally: add @useupup/angular/styles to the styles array in angular.json, or @import '@useupup/angular/styles'; in your global styles.css. The Angular quickstart covers the endpoint, and Code Examples has a ready-to-copy presign handler.

FAQ

What is the best file upload library for Angular?

For a complete uploader against your own storage, upup or Uppy. Inside a PrimeNG app, PrimeNG FileUpload. For just a drop zone, ngx-file-drop.

Which Angular upload libraries upload directly to S3?

upup, with presigned URLs from your endpoint or @useupup/server, and Uppy, with its AWS S3 plugin. With the others you write the S3 signing and upload code yourself.

Does upup's Angular package include the image editor?

No. The image editor ships in @useupup/react and @useupup/preact only. Everything else, including cloud drives, camera, screen capture and resumable uploads, works the same in Angular.

Is upup's Angular component standalone?

Yes. UpupUploaderComponent is a standalone component with the selector upup-uploader. Add it to a standalone component's imports, or to an NgModule's imports.

Are these libraries free?

Yes. All five are MIT-licensed. FilePond's full image editor, Pintura, is a separate commercial product.
