Product name & version
Aspose.Words(23.2.0) for .NET 8.0
Detailed description of the conversion issue :
When the system attempts to generate Word, it uses 251KB.
The same file we are converting into PDF, which has a size of 17.8MB.
Same 17.8MB PDF file we are converting into bytes for storage in our database.
Due to this, system dumping a large volume of data into our database.
Which is having a significant influence on our business. Users are having trouble in using our app.
Currently, we are clearing some historical data as a quick win.
Need immediate assistance to resolve this issue.

public async Task SaveInvoiceFileInEDMAsync(string invoiceCode, string templateCode = null)
{
var invoiceCodes = new List<string>() { invoiceCode };
var result = await GenerateInvoiceByPlugin(invoiceCodes, templateCode) ?? await _invoiceService.DownloadInvoiceFileAsync(new InvoiceTemplate() { InvoiceCodes = invoiceCodes });
_ = result ?? throw new Exception($"Cannot generate invoice file for {invoiceCode}");

// Convert Stream → byte[] reliably
