ImageResizer & Imageflow


We expect a usable beta of libimageflow and imageflow-server in 2016, with a stable release the following year. Imageflow makes a cross-platform ImageResizer 5 possible. If you have backed Imageflow on Kickstarter, you can already access a limited command-line version of the tool.


ImageResizer is the best image server for ASP.NET. It can be dropped into existing apps and works alongside your CMS or existing platform to eliminate manual image tasks, enable fast and adaptive websites, and improve your sales by reducing page load time.

Imageflow is open-source software which scales, edits, and optimizes images. It’s similar to ImageResizer, but faster and is not bound to the Windows API. Imageflow supports Linux, Mac, and Windows – and can be used from any programming language.

Imageflow tackles image optimization – expect smaller images, faster website load times, and increased sales.

Imageflow-server will offer a REST Querystring API like ImageResizer, but will also include a REST JSON API so you can perform complex operations on an arbitrary number of images. It will be easier to deploy, manage, and communicate with.

Imageflow is ImageResizer’s future. Without it, ImageResizer can’t become cross-platform, run on .NET Core, or be deployed on Windows Server Core.

After we deliver Imageflow, we’ll turn our attention to ImageResizer 5, which will become a thin compatibility layer over Imageflow. If you want Imageflow’s benefits sooner, consider adopting Imageflow directly as it reaches a stable phase.

Our Imageflow Kickstater ended June 28th, but we will be making new Imageflow licenses available soon.
