How to convert image to PDF from C#?

Question:I have a "trial" version of img2pdf.exe that I have tested successfully. I am writing an application in Visual Studio .NET with C# that will be deployed as a web-application on one of our servers. I have a requirement to convert .tiff files to .pdf files within the program.I know that img2pdf.exe works fine in a "command line" mode. Do you have an implementation that I can use within my VS Project? What licenses do I need for development as well as on the server?

Answer:According to your needs, you can use VeryPDF Image to PDF COM which can be used to convert raster images such as TIFF, JPM and JPEG to PDF and PDF/A or PDF documents for electronic archiving or electronic data exchange together with API: C#, Java, .NET, ect. And by the Server License, you can apply this software to the whole server. Meanwhile under one Server License, you can use the corresponding SOFTWARE on exactly one server computer that offers service to clients. If the SOFTWARE contains source codes, you have the right to modify and reuse the codes under the Server License.  In the following part, let us check how to convert tiff to PDF from  C#.
