Get MediaBastion for Windows

One MSI, no bundled extras, no account. It installs the desktop app and the command-line tool, adds shortcuts, and can check for new versions only if you turn that on.

MediaBastion 0.2.1
Released 6 September 2026 · Windows 11 and Windows 10 (64-bit) · about 97 MB
SHA-256 of MediaBastion-0.2.1.msi: 65AA522E56B419D246474804DA9D84E53B7DACACAEC2E16DB0E539BBC56D681B
Download MediaBastion-0.2.1.msi All versions and release notes No install? Use the browser edition
The installer is not yet code-signed, so Windows SmartScreen may show “Windows protected your PC” the first time. Click More info, then Run anyway. Compare the SHA-256 above with the file if you want to be sure. Code signing is one of the things tips pay for.

Requirements

Windows
Windows 11 (any edition) or Windows 10 version 22H2, 64-bit. Windows 11 Home is the reference machine.
Runtime
Nothing to install first. The MSI is self-contained and includes the .NET runtime. The dashboard uses the Microsoft Edge WebView2 runtime that ships with Windows 11 and most Windows 10 PCs.
Graphics
Any. AI features run on the CPU everywhere and use the graphics card through DirectML when it helps. A GPU with 4 GB of memory makes upscaling and the larger cutout models much faster.
Rights
An administrator account for installation. Day-to-day use does not need elevation; nothing runs in the background.
Space
Installed size about 400 MB. Optional downloads on request: FFmpeg (about 50 MB), ExifTool (about 15 MB), AI models from 5 MB to 350 MB each, speech model 142 MB.

Install

  1. Run the MSI and follow the wizard. Choose a folder or keep C:\Program Files\MediaBastion.
  2. Open MediaBastion from the Start Menu or desktop shortcut, or right-click any picture, video or audio file and choose Open with.
  3. The first screen is Easy mode. Drop files in and pick a chore. Every batch writes new files next to the originals and is recorded in the journal, so it can be undone.

Silent install for IT use:

msiexec /i MediaBastion-0.2.1.msi /qn /norestart

Verify the download

In PowerShell: Get-FileHash .\MediaBastion-0.2.1.msi. The hash must match the SHA-256 shown above; the same value is published next to the installer on the release page.

What it connects to

Nothing, by default. MediaBastion works with the network unplugged. It contacts a server only when you ask it to download FFmpeg, ExifTool, an AI model or a new version, and each of those has its own switch in Settings. The Settings page lists every address the app can ever contact.

Updates

Update checks are off until you turn them on in Settings. When on, the app compares its version with the public release list, downloads the new MSI, checks its SHA-256 and asks before installing. Every published version, including older ones, can be installed from the same panel.

Uninstall

Settings > Apps > Installed apps > MediaBastion > Uninstall, or the “Uninstall MediaBastion” shortcut in the Start Menu. Files you created stay where they are. Settings, the journal, downloaded models and tools live in %LOCALAPPDATA%\MediaBastion; delete that folder if you want everything gone.

Command line

Everything the dashboard does is also a command. mediabastion-cli help lists them: convert, resize, compress, cutout, metadata, rename, stamp, watermark, video, audio, online (fetch a video link, its captions or a transcript), xray, journal, undo and more. Recipes are plain JSON files you can keep and share.
