To check your copy, paste this into PowerShell. It prints True when the file is genuine (change the path if you saved it somewhere other than Downloads):

(Get-FileHash "$env:USERPROFILE\Downloads\CrunchySetup.exe").Hash -eq 'ce456e98c8c341d928dadee93e4aea56a327540c79f912c4da148b4bd6b19906'
  • No admin rights needed. Installs just for you, no UAC prompt.
  • SmartScreen warning? Expected for new indie apps. Here's what to click.
  • Nothing else bundled. No toolbars, no ads, no account.
  • Video and audio tools optional. After installing, the setup offers FFmpeg for videos and audio (about 46 MB, downloaded in the background). About the tools.
Prefer the terminal? One line in PowerShell:
irm https://crunchy.h190k.com/update/CrunchySetup.exe -OutFile $env:TEMP\CrunchySetup.exe; Start-Process $env:TEMP\CrunchySetup.exe

Downloads the latest installer to your temp folder and starts it. Same file as the button above.

Crunch from the command line
crunchy --level maximum --target 25MB file.pdf

Pass files or folders plus options like --level and --target for scripts and batch jobs. Tick the optional Add Crunchy to PATH box in the installer so crunchy works from any PowerShell or Command Prompt window.

Full command-line guide

Install

Up and running in a minute.

  1. Download

    Grab CrunchySetup.exe with the button above. It's the same stable link every release.

  2. Run the installer

    If SmartScreen says "Windows protected your PC", click More info → Run anyway (see how). Its last step offers the video and audio tools (FFmpeg) as an optional background download.

  3. Crunch

    Launch Crunchy from the Start menu and drop in your first files, or right-click any file in Explorer and choose Compress with Crunchy.

Getting past SmartScreen

Crunchy isn't code-signed yet, so Windows may show a blue "Windows protected your PC" window the first time. It's a two-click job, and you can verify the checksum first if you like.

  1. Click More info.

  2. Check the app is CrunchySetup.exe, then click Run anyway.

The video and audio tools

Video and audio compression run on FFmpeg, a free, open-source (GPL) video and audio toolkit. It's too big to ship inside the setup, so once Crunchy is installed, the setup's last page offers to download it in the background.

How video compression works
  • About 46 MB to download. Getting the tools needs an internet connection; installing Crunchy and compressing never do.
  • Optional. You can say no. Crunchy offers the download again when you add a video or audio file (Settings › Video and audio tools always has it), and everything else works without it.
  • Kept up to date. When a newer FFmpeg is out, Crunchy asks, then downloads it, checks its SHA-256 and installs it without a reinstall. crunchy --deps shows what's installed.
  • A separate program. FFmpeg runs next to Crunchy, and its licence and a link to its source code ship with the app. Credits.

Updating

Crunchy checks /update/latest.json at launch and once a day while it's open. When a new version is out it downloads the installer, verifies its SHA-256 and runs it for you. You can also just download and run the latest installer over your current install.

Why the warning?

New, unsigned apps trigger SmartScreen until they build up reputation. It doesn't mean something is wrong, but it's good practice to verify the checksum before running any installer.

Uninstalling

Open Settings → Apps → Installed apps, find Crunchy and choose Uninstall. Your compressed files stay where you saved them.
