You can take a stream and convert it to PDF using the DocumentConverter class. Here is an example that you can build on: static void Main(string[] args) { var outBytes = ConvertStreams(new MemoryStream(inBytes)); File.WriteAllBytes(C:\Output\file.pdf outBytes.ToArray()); } static MemoryStream ConvertStreams(Stream inputStream) { var ms = new MemoryStream(); //output stream using var document = DocumentFactory.LoadFromStream(inputStream new LoadDocumentOptions()); using var documentConverter = new DocumentConverter(); var jobData = new DocumentConverterJobData { Document = document DocumentFormat = DocumentFormat.Pdf OutputDocumentStream = ms }; var job = documentConverter.Jobs.CreateJob(jobData); documentConverter.Jobs.RunJob(job); if (job.Status == DocumentConverterJobStatus.Success) return ms; else return null; } https://www.leadtools.com/help/sdk/v22/tutorials/dotnet-console-convert-files-with-the-document-converter.html
