Image Optimizer for Visual Studio

Build status

Download this extension from the VS Gallery or get the nightly build.


Uses industry standard tools to optimize any JPEG, PNG and Gifs - including animated Gifs. It can do both lossy and lossless optimization.

Features

Adds a right-click menu to any folder and image in Solution Explorer that let's you automatically optimize all PNG, GIF and JPEG files in that folder.

  • Optimizes PNGs (uses Zopfli compression)
  • Optimizes GIFs
  • Optimizes animated GIFs
  • Optimizes JPGs (uses MozJPEG)
  • Works on single images files or entire folders
  • Copy any image as base64 dataURI to clipboard

Optimize images

Simply right-click any file or folder containing images and click one of the image optimization buttons.

Context menu

You can also right-click a folder to optimize all images inside it.

Best quality

If you chose best quality optimization, the tool will do its optimizations without changing the quality of the image.

Best compression

If you decide to sacrifice just a small amount of image quality (which in most cases is unnoticeable to the human eye), you will be able to save up to 90% of the initial file weight. Lossy optimization will give you outstanding results with just a fraction of image quality loss.

Output window

The Output Window shows the detailed output from the optimization process and progress is displayed in the status bar.

Performance

Optimizing an image can easily take several seconds which feels slow. This extension parallelizes the workload on each CPU core available on the machine. This speeds up the optimization significantly.

API for extenders

Any extension can call the commands provided in the Image Optimizer extension to optimize any image.

public void OptimizeImage(string filePath)
{
	try
	{
		var DTE = (DTE2)Package.GetGlobalService(typeof(DTE));
		Command command = DTE.Commands.Item("ImageOptimizer.OptimizeLossless");

		if (command != null && command.IsAvailable)
		{
			DTE.Commands.Raise(command.Guid, command.ID, filePath, null);
		}
	}
	catch (Exception ex)
	{
		// Image Optimizer not installed
	}
}

The commands are:

  • ImageOptimizer.OptimizeLossless - Optimize for best quality
  • ImageOptimizer.OptimizeLossy - Optimize for best compression
