You can use the JavaScript LoadFromUri method provided through the LEADTOOLS toolkit to load a PDF Document that is stored in a remote URL. From here, you can save the document to cache and then pass the DocumentId into the DocumentConverter which will allow you to save the document to PDF locally. The DocumentConverter saving will need to be performed through a backend service such as C#. The sample code and examples in the links will show how to do this:
loadDocument = () => {

      const index = this.processedCount;
      const loadOptions = new lt.Document.LoadDocumentOptions();
      DocumentHelper.log("Loading " + this.urls[index]);
      lt.Document.DocumentFactory.loadFromUri(this.urls[index], loadOptions)
         .done((childDoc) => {
            // Finished, save the document and load next
            this.loadedCount++;
            this.childDocs.push(childDoc);
         })
         .fail(DocumentHelper.showServiceError)
         .always(() => {
            this.processedCount++;
            if (this.processedCount >= this.childDocCount) {
               // All children loaded, if we did not have an error continue with the example
               if (this.loadedCount === this.processedCount) {
                  DocumentHelper.log("All documents loaded", this.childDocs);
                  this.createDocument();
               }
            }
            else {
               this.loadDocument();
            }
         });
   }

   logDocument = (doc) => DocumentHelper.log("Name: " + doc.name + " Pages: " + doc.pages.count + " Documents: " + doc.documents.count, doc);

      // Save the ID so we can load it
      const documentId = doc.documentId;

      // Now save this 'parent' document into the cache
      lt.Document.DocumentFactory.saveToCache(doc)
         .done(() => {
            DocumentHelper.log("Document saved to cache at " + documentId) // document ID needed for DocumentConverter

Step 1. Create a .NET application and install Spire.Pdf.dll via NuGet.

Step 2. Use the following code snippet to download the PDF document from URL.
using System.Collections.Generic;
using System.IO;
using System.Net;
using Spire.Pdf;

namespace DownloadPdfFromUrl
{
    class Program
    {
        static void Main(string[] args)
        {
            PdfDocument doc = new PdfDocument();

            WebClient webClient = new WebClient();

            using (MemoryStream ms = new MemoryStream(webClient.DownloadData("https://c342635.ssl.cf1.rackcdn.com/6ac890fe-ad9a-11eb-9f49-42010a8a0027")))
            {
                doc.LoadFromStream(ms);
            }

            doc.SaveToFile(@"C:\Users\Administrator\Desktop\result.pdf", FileFormat.PDF);
        }
    }
}
