this problem solved in this way

1) I installed Imazen.WebP nuget. 2) I downloaded the 32bit dll from here and added it to release folder. 3) I added "using Imazen.WebP; " in top of my code 4)I used this code to convert jpg to webp.

var file = await bot.GetFileAsync(update.Message.Photo.LastOrDefault()?.FileId);
var jpgFileName = file.FileId + ".jpg";
using (var saveImageStream = System.IO.File.Open(jpgFileName,FileMode.Create))
{
    await bot.DownloadFileAsync(file.FilePath, saveImageStream);
    await bot.SendTextMessageAsync(update.Message.Chat.Id, "please wait...");
}
var webpFileName = file.FileId + ".webp";
using (Bitmap bitmap = new Bitmap(jpgFileName))
{
    using (var saveImageStream = System.IO.File.Open(webpFileName, FileMode.Create))
    {
        var encoder = new SimpleEncoder();
        encoder.Encode(bitmap, saveImageStream, 20);
    }
}
using (var stream = System.IO.File.Open(webpFileName, FileMode.Open))
{
    await bot.SendStickerAsync(update.Message.Chat.Id, stream);
}
System.IO.File.Delete(jpgFileName);
System.IO.File.Delete(webpFileName);

and it worked correctly
