Compress Word Files Online

Compress Word documents online: drag and drop, pick basic compression, export as DOCX, and instantly shrink your document size for free.

Why Compress Word Files?

Word documents can balloon in size—especially when you add high‑res or uncompressed images—so it’s important to optimize Word document size. Luckily, Smallpdf isn’t just for PDFs: our online PDF compressor also helps you reduce Word file size for free, without downloads or sign‑ups. Whether you’re emailing reports, collaborating with colleagues, or archiving large documents, keeping files lean speeds up uploads and saves storage space. In this article, you’ll learn how to shrink a Word document online with our tool (plus explore other handy features).

How to Compress a Word File Online

Want to compact Word doc in seconds? Just follow these steps:

1. Drag and drop your Word file into the compressor.
2. Choose “Basic compression” and continue.
3. Click on “Export As” and choose the option “Word.”
4. All done—Your compact Word doc is ready for download!

How This Tool Slims Down Word Documents

The list above should help you understand how to compress Word documents online, but you might still have questions—for example, “how can a PDF compressor also compress Microsoft Word files?”

Here’s how we decrease Word document size: first, our PDF compressor uses Smallpdf’s conversion technology to turn your document into a PDF document; then, we compress pictures and text in that PDF. You can then choose to export your newly compressed file in your format of choice, including Word, Excel, PDF, or PPT.

If you’re sharing a document that doesn’t need to be edited by its recipient, you can skip the last step in this process and keep your file in PDF format. Instead of choosing “Export As,” just download the compressed PDF version of your Microsoft Word file via the download button.

For security reasons, we’ll remove your file from our servers an hour after you decrease Word document size online. If you want to keep this file there for a longer period, you can store it with our file storage feature or generate a shareable URL.

Can You Compress More Than One Word Document?

Smallpdf’s Word document compressor workflow is simple enough—assuming you only need to reduce Word file size for a single document, anyway. On the other hand, repeating this process for multiple files could feel like a hassle.

Fortunately, Smallpdf Pro users can process multiple documents at once. Once you have an active Smallpdf Pro subscription, open the PDF compressor and upload as many Word files as you want. This batch mode acts as a powerful DOCX size optimizer, and when you’re done, you can download a ZIP file containing all your compressed Word documents.

Having a Pro account will also allow you to use Strong compression on your files. This option is perfect if you have a large file that’s too large for our Basic compression to shrink Word documents effectively.

Not a Smallpdf Pro user? Don’t worry—you can take advantage of our seven-day free trial to test these compression options and other Pro-exclusive features.

Do Even More With Smallpdf

Though our PDF compressor is certainly powerful, we’ve only scratched the surface of what Smallpdf can do for you. From Word size optimization to AI‑powered features, here’s what else you can do:

Compress Pictures and More

While our compressor can shrink PDFs and Word documents with ease, these aren’t the only file types it can work with. You can also drag and drop documents saved in other Microsoft 365 formats to our online platform—including PowerPoint presentations, Excel spreadsheets, and even JPG images.

When you upload files like these, we’ll simultaneously upload, convert, and compress pictures, spreadsheets, and more. And after you compress your documents, you can export them in their original format.

Edit Your PDF Documents

The PDF format is undeniably popular, but it can also be surprisingly inconvenient when you want to edit a document. The good news is that Smallpdf’s PDF Editor can help.

After uploading a document to this tool, you can add images, highlights, shapes, and annotations throughout your PDF file. If you have Smallpdf Pro, you’ll even be able to edit existing text in this document.

Merge Your PDFs

Sending multiple PDF files to a single person can get unwieldy—especially when these files could just as easily be shared as a single document. If you have several PDFs that you’d like to combine, give our Merge PDF tool a shot.

While using this tool, you’ll drag the files you want to merge into your browser window. After you upload these documents and click “Finish,” you’ll be able to download a single file with the contents of all the documents you uploaded.

Explore The Possibilities of AI

In addition to the tools listed above (and many others), Smallpdf’s newest capabilities allow users to work with their files in new ways thanks to AI technology. Our AI-powered tools include:

• Chat with PDF. While using this tool, Smallpdf users can ask their documents questions and get immediate answers.
• AI PDF Summarizer. Our AI PDF Summarizer creates “at-a-glance” overviews of PDFs and other files.
• Translate PDF. With Smallpdf’s PDF Translator, you can easily translate summaries of your documents into other languages.

Compress DOCX Online the Easy Way

When you know how to compress DOCX online, you can use this well-known file format as efficiently as possible. Of course, you shouldn’t rely on just any Word file size reducer for this job—if you aren’t careful, you might have to pay for a subscription or deal with hassles like mandatory registration before you can compress these documents.

By using Smallpdf for your file compression needs, you can shrink your Microsoft Word documents (and many other files) in mere moments—no registration required. And while Smallpdf Pro users can enjoy additional features, our basic Word document compressor is 100% free!
