You can use LEADTOOLS Imaging SDK technology in your application.
https://www.leadtools.com/sdk/engine/imaging
For your use-case you can leverage the RasterCodecs class. The RasterCodecs class provides support for loading and saving raster image files, including but not limited to JPEG, TIFF, BMP, PNG, etc.
https://www.leadtools.com/help/sdk/v22/dh/co/rastercodecs.html

Here is some sample code:
// File path to your BMP/TIF/TIFF input file
string filename = @"File path to your BMP/TIFF input file";
string outputfile = @"File path to your JPEG/PNG output file";
// Create a new instance of RasterCodecs
using (RasterCodecs _codecs = new RasterCodecs())
{
    using(RasterImage _image = codecs.Load(filename);
        _codecs.Save(_image, outputfile, RasterCodecs.Jpeg, 0);
}

for each source and target filetypes you have to come up with own logic.

For example; if you want to convert .bmp to .jpg a separate logic, and for .bmp to .png a separate logic has to be written

Refer this article for .bmp to jpeg conversion, you wont get the same quality as source image

Its hard to achieve by coding,
you can use npm package:- https://www.npmjs.com/package/tiff-to-png
var ConvertTiff = require('tiff-to-png');

var options = {
  logLevel: 1
};

var converter = new ConvertTiff(options);
var location = '/srv/www/mysite/public/documents'; // where to save

converter.convertOne('/home/tiffs/document_one.tif', location); // file path, location
