FilePond is an MIT-licensed JavaScript file upload library for front-end developers who need drag-and-drop, clipboard paste, API-driven uploads, and automatic image optimization in one dependency.

What it is

FilePond is a vanilla JavaScript upload library published to npm as filepond, developed by PQINA and documented at pqina.nl/filepond. It lives in the browser ecosystem and carries a plugin architecture: the core handles file intake and transport, while optional plugin packages add validation, previews, and image processing. Official framework adapters ship separately as react-filepond, vue-filepond, ngx-filepond, svelte-filepond, and jquery-filepond, so the same upload behaviour is available across those rendering layers. The repository holds 16,393 stars, 848 forks, and 142 open issues, with the last push on 15 September 2026.

The concrete problem it solves is the file input itself. A bare input element gives no drag-and-drop, no paste handling, no progress reporting, no chunking, and no client-side image work, so teams write the same upload widget repeatedly. FilePond accepts directories, files, blobs, local URLs, remote URLs, and Data URIs. It runs asynchronous AJAX uploads, supports chunk uploads, can encode files as base64 data, and can send files along with a form post. On the image side it resizes, crops, filters, and fixes EXIF orientation before bytes leave the browser, which is the specific work it replaces in photo and video editing interfaces.

Key capabilities

• Accepts directories, files, blobs, local URLs, remote URLs, and Data URIs as upload sources.
• Adds files by drag-and-drop, filesystem selection, copy and paste, or programmatic API calls.
• Performs asynchronous AJAX uploads with chunk upload support, base64 encoding, and form post submission.
• Applies image optimization: automatic resizing, cropping, filtering, and EXIF orientation correction.
• Is accessible and tested with assistive technology such as VoiceOver and JAWS, and is navigable by keyboard.
• Scales responsively to available space and works on both mobile and desktop devices.
• Extends through plugins including filepond-plugin-file-validate-size, filepond-plugin-file-validate-type, filepond-plugin-image-preview, filepond-plugin-image-crop, filepond-plugin-image-resize, filepond-plugin-image-transform, filepond-plugin-file-encode, and filepond-plugin-file-metadata.

Who uses it and how

• Vanilla JavaScript projects use it directly through the filepond package without a framework wrapper, matching the vanilla topic.
• React, Vue, Angular, Svelte, and jQuery teams consume the matching adapter package and follow the StackBlitz live demos published for each.
• Applications handling user-supplied photos use the image plugins to resize, crop, filter, and correct EXIF orientation before upload, reducing payload size.
• Products with accessibility requirements rely on its keyboard navigation and VoiceOver and JAWS testing.
• Teams that also need browser-side image editing pair it with Pintura, the JavaScript image editor from the same vendor.

Getting started

Install the filepond package from npm, import the core, and register the plugins required for the target case, or install the adapter package for React, Vue, Angular, Svelte, or jQuery. Setup, plugin registration, and server configuration are documented at pqina.nl/filepond/docs, and a FilePond v5 alpha is available on the v5 branch for testing.

How it compares

The facts name no competing upload library, so the only other tool listed alongside it is Pintura, a commercial JavaScript image editor that integrates with FilePond rather than substituting for it. On that basis FilePond stands alone in this registry as an upload library, and Pintura covers the adjacent editing step.

When to use it — and when not to

Choose it when the front end needs a configurable, accessible upload widget and the team is prepared to run its own server endpoint, since FilePond is a browser library and the README names no storage, database, or mail service. Avoid it if the requirement is a managed hosted upload service with server-side processing included, or if the project cannot absorb plugin registration and bundler configuration. Note also that version 5 remains an alpha on a branch, and the repository carries 142 open issues, so the stable line is the safer default for production.

npm install filepond

import * as FilePond from 'filepond';

// Create a multi file upload component
const pond = FilePond.create({
    multiple: true,
    name: 'filepond',
});

// Add it to the DOM
document.body.appendChild(pond.element);
