Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Adding an efficient file uploader solution that is easy to use, secure, and comes with rich features is rewarding for your application or website.

It can make file uploading an effortless task no matter what device or browser you use. At the same time, you can ensure your app is safe from security and compliance risks.

But finding a file uploader like that seems to be a little tricky since you have a variety of options available.

To make this easy for you, I’ve come up with this article that tells you a few things about this solution, features to look for, and the best file uploaders for your apps and sites.

Let’s start!

What Is a File Uploader?

A file uploader is a software solution you can use to upload, process, and deliver files to your website or application. It basically accepts and manages users’ files such as images, PDFs, videos, and other documents.

A file uploader on a site or app may look like an actionable button. When you click this button, you can see a dialogue box opened for you to choose and submit a file. Websites need a file uploader to accept user-generated content. It can be:

  • An explanatory image on a blog post
  • Product images on an eCommerce site like Amazon
  • Portfolios or CVs on Indeed
  • Pictures and Reels on Instagram
  • Videos on a YouTube channel

Features a Typical File Uploader?

A typical file uploader on a website or app should have features to ensure proper data security, compliance, a friendly interface, data storage, etc. Let’s look at some of the features that make a file uploader a good choice.

User-friendly Interface

A file uploader interface that’s user-friendly yet intuitive is tough to find. But if you want your entire team to use your file uploader without any confusion or difficulty, you must choose the one that can strike a good balance between the two factors. For this, you can look for features like:

  • A preview option so that users can preview files before they finish uploading them on the site or app, making sure they have chosen the right one.
  • Accommodates large files without compromising the speed. It is handy when you want to upload large video files on sites like YouTube and other use cases.
  • Supports multiple uploads to enable uploading multiple files simultaneously.
  • A responsive user interface lets users upload files conveniently no matter what device they use.

Drag and Drop

A drag-and-drop feature is a must-have for file uploaders. It makes your work easier and more convenient since you can drag a file from somewhere on your computer and drop it on the file uploader.

For example, if you want a file from your browser’s downloads panel or an already open file, you can drag and drop the file and upload it quickly with a simple click.

It will attach the file you may want to preview and then submit. This saves you from the struggles of clicking multiple times and wandering across different folders to choose that one file.

Apart from this, features such as image editing in the browser is a desirable feature so that you can edit the pictures and optimize their look to suit your app and website design. You can also perform operations on an image such as crop, rotate, resize, blur, mirror, invert, etc.

Supports Multiple Sources

A good file uploader will support file uploading from various sources, not just the users’ device storage. So, when you choose a file uploader, check whether it gives you this option or not. You must be able to integrate it with many upload sources such as:

  • Social media platforms like Instagram, Facebook, etc.
  • Local webcams so that users can take images instantly using their mobile or computer camera and upload them straight away.
  • Cloud solutions like Google Drive, OneDrive, Dropbox, etc.
  • Remote URLs where you can upload a file by copying a public link and pasting it into the file upload dialog
  • Other devices such as Flickr, Evernote, Huddle, and more

However, it’s necessary to have all of them. If you use some of these solutions and you require the file to upload, you can look for a file uploader that can support those sources. Having said that, the more, the merrier!


Data security and privacy are big concerns due to the rising cybersecurity risks globally. When you accept user-generated content, your website is subjected to potential risks and threats such as malware, data theft, unauthorized access, etc.

Hence, you must choose a file uploader platform that can secure your site or app from security and compliance risks. For this, you can consider a few points:

  • Scan all the files using anti-malware tools
  • Use an allowlist of file types to verify the file types that a user can upload while rejecting unapproved ones.
  • Define file size with a maximum and minimum size limit to mitigate service outages
  • Upload the files to an external directory and implement data storage outside the Webroot to safeguard the files from security issues and data loss
  • Maintain compliance with regulations such as GDPR, HIPAA, etc. applicable in your country or region
  • Use SSL certificates to secure data transfers between the users’ browsers and the web server.

If the file uploader you have chosen offers these security features, it’s a great asset.

Now, let’s look at some of the best file uploader solutions for your applications and sites.
