The ASP.NET Core File Upload is a control for uploading one or multiple files, images, documents, audio, video, and other files to a server. It is an improved version of the HTML5 upload control (<input type="file">) with a rich set of features that include multiple file selection, progress bars, auto-uploading, drag and drop, folder (directory) uploading, file validation, and more.
Select multiple files and upload them to a server at the same time. This is useful for uploading images to a gallery and for file-sharing applications.
Upload multiple files by simply dragging them from the file explorer to the drop area (drop zone), which is a more user-friendly way to select and upload multiple files.
Accepts a folder (directory) as a file source for uploading all the files (including subfolders) of the selected folder.
Using the AJAX library, the ASP.NET Core File Upload control easily uploads files in asynchronous mode.
Manage upload of large file uploads efficiently using chunk upload that slices a large file into smaller chunks and uploads to the server in a sequential order asynchronously.
Allows users to create a custom UI in the ASP.NET Core File Upload based on their application need using a wide range of template options.
Cutting edge design with 5+ built-in themes such as Fluent, Tailwind CSS, Bootstrap, Material, Fabric, and more. Utilize the online Theme Studio tool to customize themes of File Upload easily.
Enables users from different locales to use the File Upload by formatting dates, currency, and numbering to suit their preferences.

We do not sell the ASP.NET Core File Upload separately. It is only available for purchase as part of the Syncfusion team license. This contains over 1,900 components and frameworks, including the ASP.NET Core File Upload. The price of the team license starts at $395 per month for 5 developers, and includes support and updates until the subscription expires. In addition, we might offer discounts based on currently active promotions. Please contact our product specialists today to see if you qualify for any additional discounts.
You can find our ASP.NET Core File Upload demo, which demonstrates how to render and configure the File Upload control.
No, our 1,900+ components and frameworks for web, mobile, and desktop, including our ASP.NET Core File Upload, are not sold individually. They are only available as part of a team license. However, we have competitively priced the product, so it only costs a little bit more than what some other vendors charge for their File Upload control alone. We have also found that, in our experience, our customers usually start off using one of our products and then expand to several products quickly, so we felt it was best to offer all 1,900+ components and frameworks for a subscription fee that starts at $395 per month for a team of 5 developers. Additionally, we might be able to offer discounts based on currently active promotions. Please contact our product specialists today to see if you qualify for any additional discounts.
No, this is a commercial product and requires a paid license. However, a free community license is also available for companies and individuals whose organizations have less than $1 million USD in annual gross revenue, 5 or fewer developers, and 10 or fewer total employees.
A good place to start would be our comprehensive getting started documentation.
