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 https://stackoverflow.com/questions/41665/bmp-to-jpg-png-in-c-sharp

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
