How to Install Mass Image Compressor via Winget

Mass Image Compressor (version 4.x for Windows OS) is now distributed through Winget, apart from our traditional distribution channels like SourceForge/GitHub/Microsoft Store, enabling streamlined deployment and upgrades, especially for IT administrators and power users.

Here is how you can install Mass Image Compressor on your Windows 10+ and Windows Server 2019+

Step 1: Update Winget Source

Ensure Winget has the latest package metadata as Cognirush.MassImageCompressor package is added recently (May, 2025).

Run this command in command prompt:

winget source update

Step 2: Uninstall Previous Version

Mass Image Compressor (MIC) installed via Winget cannot coexist with earlier 3.x or 4.x versions due to naming conflicts. If you need to install 3.x and 4.x on your system, avoid getting MIC through Winget.

Uninstall any existing version via:

Option A: Winget

Run this command:

winget uninstall --id=Cognirush.MassImageCompressor -e

Option B: Add or Remove Programs

• Open Settings → Apps → Installed Apps
• Locate and remove Mass Image Compressor

Step 3: Install Version 4.x via Winget

Install using the official Winget command:

winget install --id=Cognirush.MassImageCompressor -e

This installs the latest supported version (4.x) optimized for Windows 10 (updated), Windows 11, and modern Windows Server builds (Updated Windows Server 2019 and above). The package is unsigned but installs normally through Winget without additional flags. You may choose Microsoft Store edition if unsigned package is an issue to you.

Notes for Legacy Users

Version 3.x remains available for older systems like Windows 7, Windows 8, or early Windows 10/Server 2019 builds (no support for winget). Visit SourceForge to get version 3.x

Troubleshooting: Error While Compression

If your system doesn’t have Microsoft Visual C++ 2015 (or higher) Redistributable installed, you may see below error (from a 3rd party dependency called oxipng):

“The code execution cannot proceed because VCRUNTIME140.dll was not found. Reinstalling the program may fix this problem.”

Most systems will not face the problem but if you face this, just install the required dependency from Microsoft: https://aka.ms/vs/17/release/vc_redist.x64.exe

The compression may still work without this but PNGs may not compress well without resolving this error first so it is highly recommended.
