Method 2: Utilize Microsoft Word for Compression​

Surprisingly, Microsoft Word can also serve as a PDF compressor. This method is best suited for PDFs that are lightly formatted because Word may slightly alter complex layouts.

• Open Your PDF in Word:
• Launch Microsoft Word.
• Go to File > Open > Browse and select your PDF file.
• Accept the prompt that warns you about potential layout changes.
• Export as a Compressed PDF:
• Click File in the top-left corner.
• From the sidebar, select More > Export, then click on Create PDF/XPS Document.
• On the Publish as PDF or XPS dialog box, check the option labeled Minimum Size (Publishing Online).
• Choose your destination folder, provide a new file name, and click Publish.

Summary: This method repurposes a familiar tool, making PDF compression accessible for those who routinely work with Word. However, keep an eye on formatting alterations, especially for richly formatted source PDFs.

Method 3: Web-Based Compression Tools​

If you only have a few PDFs to compress and prefer not to install any software, web-based tools can be a quick alternative. Popular options include:

• Smallpdf
• iLovePDF
• PDF Compressor

How to Use a Web-Based Tool (e.g., Smallpdf):​

• Upload Your File:
• Navigate to the Smallpdf website.
• Click on Choose Files or simply drag and drop your PDF into the designated area.
• Select Compression Options:
• You’re usually offered options such as Basic or Strong compression:
• Basic: Achieves moderate compression while maintaining standard resolution.
• Strong: Offers more intense compression, albeit with potential quality loss.
• Note that free plans may limit the number of times you can use high-intensity compression.
• Download and Secure:
• Once compression is complete, click Download to save your file.
• For added privacy, delete the file from the web service’s server if given the option (typically via a delete or trash can icon).

Important Caution: Avoid using web-based tools for files containing sensitive or proprietary data. Offline methods are highly recommended for confidential documents.
Summary: Web tools are efficient and user-friendly but always consider privacy concerns, especially when working with confidential PDFs.

Method 4: Create a Compressed Archive with 7‑Zip​

7‑Zip, a popular archiving tool, takes an indirect approach by packaging your PDF into a compressed archive. This method is particularly effective when you have multiple PDFs or if you need to compress files for transport.

• Download and Install 7‑Zip:
• Obtain 7‑Zip from its official site.
• Install the app and then restart your Windows 11 system if needed.
• Compress Your PDF:
• Open File Explorer (Windows+E), right-click your PDF file, and select Show More Options.
• Choose 7‑Zip > Add to Archive.
• From the Add to Archive dialog, choose 9 - Ultra under the Compression Level dropdown.
• Optionally, ensure your archive format is set to .zip for maximum compatibility.
• Click OK to create the compressed archive.

Summary: Using 7‑Zip is an excellent way to compress single or multiple PDF files without altering the content, though the output is in archive format rather than as a single PDF file.
