title: ImageFactory is generating .webp file that is larger than .jpeg file
body: <p>I have an ASP.NET Core based WebAPI. I am trying to convert uploaded <code>.jpeg</code> images to <code>.webp</code>. I tried using <a href="https://imageprocessor.org/" rel="nofollow noreferrer">ImageProcessor</a> library along with the <a href="https://www.nuget.org/packages/ImageProcessor.Plugins.WebP/" rel="nofollow noreferrer">ImageProcessor.Plugins.WebP</a> to generate the <code>.webp</code> compressed file. Here is the code I used</p>
  
  <pre><code>public async Task&lt;IActionResult&gt; Store(IFormFile file)
  {
      if(!ModelState.IsValid) 
      {
          return Problem("Invalid model!");
      }
  
      string absoluteFilename = Path.Combine("d:/uploaded_images", Path.GetRandomFileName() + ".webp");
  
      using var stream = new FileStream(absoluteFilename, FileMode.Create);
      using ImageFactory imageFactory = new ImageFactory(preserveExifData: false);
      imageFactory.Load(file.OpenReadStream())
                  .Format(new WebPFormat())
                  .Quality(100)
                  .Save(stream);
  
      return Ok(absoluteFilename);
  }
  </code></pre>
  
  <p>But the above code takes an 83.9KB JPEG file and created a 379KB WEBP file. I tried to convert my JPEG file to WEBP using <a href="https://image.online-convert.com/convert-to-webp" rel="nofollow noreferrer">an online converter</a> and the outcome was  73KB.</p>
  
  <p>How can I correctly convert the <code>.jpeg</code> file to <code>.webp</code>?</p>
