For a safe and efficient setup, you can use the official Office Deployment Tool (ODT) to "compress" your installation by only including the specific apps you need, or use built-in tools to reduce the size of your actual Office documents. 1. Optimize Installation Size (Office Deployment Tool)

Instead of a "highly compressed" unofficial file, use the Office Deployment Tool (ODT) to install a lightweight version of Office by excluding unnecessary apps (like Publisher or Access).

Step 1: Download the ODT from the official Microsoft Download Center.

Step 2: Create a configuration .xml file using the Microsoft 365 Apps Admin Center to select only the essential apps (e.g., Word, Excel, PowerPoint).

Step 3: Run the installation via Command Prompt as an administrator to deploy only your selected, "compressed" suite. 2. Compress Existing Office Files

If you are looking to reduce the disk space used by your Word, Excel, or PowerPoint documents, use these built-in methods:

Compress Images: Select any image in a document, go to Picture Format > Compress Pictures, and choose a lower resolution (e.g., 96 or 150 ppi) to drastically shrink the file size.

Binary Format (.xlsb): Save large Excel workbooks as Excel Binary Workbook (.xlsb). This format is much more compressed and faster to open than the standard .xlsx.

Remove Editing Data: In File > Options > Advanced, select Discard editing data to remove stored information used to undo image edits.

Zip Folders: Right-click your Office files or folders and select Send to > Compressed (zipped) folder for easy sharing and storage. 3. Lightweight Alternatives for Older PCs

If your PC has limited resources (less than 4GB RAM or low disk space), consider these highly optimized alternatives that fully support Office formats: Zip and unzip files - Microsoft Support

This method uses Microsoft’s own deployment tool coupled with high-compression archiving.

The Verdict: Does It Actually Work?

Technically speaking, yes—for older versions (Office 2007, 2010, sometimes 2016). You can find highly compressed versions that will launch Word and let you type a letter.

But the performance is often terrible. Loading takes minutes. Printing fails. Cloud saving is impossible. And you are one Windows Update away from the whole thing breaking.

For modern Office (2019, 2021, 365): No. The activation servers are too sophisticated. Most "highly compressed" copies of modern Office are actually just trial installers with a keygen—which is where the real malware hides.

Q4: Why do some YouTube videos show "Office 2024 highly compressed 80MB"?

They are lying. Often, the video guides you to a link shortener where you wait 60 seconds, then download a .txt file with a password to a non-existent archive. It’s a common clickbait tactic.
