Easy File Uploading With JavaScript | FilePond by PQINA

Upload anything, from anywhere.

A JavaScript library that can upload anything you throw at it, optimizes images for faster uploads, and offers a great, accessible, silky smooth user experience.

Framework Adapters

The core library is written in vanilla JavaScript and therefor can be used everywhere.

Below you can find a list of adapters that make it easier to use FilePond with your favorite framework.

Example Implementations

Let's look at two quick example implementations and see what FilePond is capable of.

Multi-file upload

  • Add the multiple attribute to a file input to create a multi-file drop area.
  • Limit the maximum amount of files with the data-max-files attribute.
  • Drop an image and FilePond will render a quick preview. It'll also correct mobile photo orientation info.

The classic file input element we'll enhance
to a file pond, configured with attributes
<input type="file" 
// We want to preview images, so we register
// the Image Preview plugin, We also register 
// exif orientation (to correct mobile image
// orientation) and size validation, to prevent
// large files from being added

// Select the file input and use 
// create() to turn it into a pond

Profile picture selection

  • Dropped images will automatically be cropped to a 1:1 aspect ratio and scaled to fit a 200 × 200 bounding box.
  • Should you accidentally drop an image on the browser window, FilePond will prevent the browser from opening it.
  • In this example the image is stored in base64 format so it can be sent with the form post.

to a file pond, we moved the configuration
properties to JavaScript
<input type="file" 
    accept="image/png, image/jpeg, image/gif"/>
// We register the plugins required to do 
// image previews, cropping, resizing, etc.

// Select the file input and use 
// create() to turn it into a pond
    labelIdle: `Drag & Drop your picture or <span class="filepond--label-action">Browse</span>`,
    imagePreviewHeight: 170,
    imageCropAspectRatio: '1:1',
    imageResizeTargetWidth: 200,
    imageResizeTargetHeight: 200
