The Blazor File Upload is a component for uploading files, images, documents, and audio and video files to a server. The File Upload works in both WebAssembly and Server-side Blazor apps, and also supports a rich set of features that include multiple file selection, progress bars, auto-uploading, drag and drop, folder (directory) uploading, file validation, and more.

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 Blazor File Upload component 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.

No, our 1,800+ components and frameworks for web, mobile, and desktop, including our Blazor 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 component 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 1,800+ 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.
