How to reduce the size of your PPT files significantly, at no cost, using Smallpdf. No watermark, no registration, and no installation.

We’ve come across many large PPT files in our years of compressing digital documents, from handbooks to training manuals and product catalogs. One of the most common needs for compressing PPT is to send them via email, where the file size cap is usually 20 MB. You can use our online compress tool to shrink your PPT down significantly.

How To Compress a PPT File for Free

  1. Upload your PPT to the compress tool, then choose “Basic Compression.”

  2. Download the file and go to our PDF to PPT converter.

  3. Drag the downloaded file into the orange toolbar.

  4. Once the tool has converted the file, go ahead and hit “Download.”


Convert, compress, and download your PPT using Smallpdf

The first step will simultaneously convert your PPT to PDF and compress its content. The second will revert the file back to PPT format, in a considerably smaller size. You can get started for free right away, without having a Smallpdf account—just go to the tool and drag your file in!

Will the Document’s Formatting Remain the Same?


We aim to maintain the layout and quality of your document as close to the original PPT as possible. Smallpdf caters to over 40 million users every month and uses the most reliable software library on the internet to convert files from one format to another. So you can trust that we will only churn out the absolute best conversion quality.

There are extra measures that you can take to ensure that the final content resembles its original form perfectly. You can “embed” the fonts of the text in your PowerPoint presentation. You’ll find this option under “Preferences” in PowerPoint. Doing this will ensure that the fonts remain the same, even when we don’t have the same ones on our servers.

If you need to compress multiple PowerPoint files or want to compress images and other formats, you can repeat the same process via the two tools: compress and convert. Smallpdf accepts all Office-related files and JPG images. If you go Pro, you can also compress files in batches and we’ll conveniently store them in a zip file for you. Why not sign up for a 7-day free Pro trial before fully committing?

And that’s all there is to it! Enjoy compressing your PPT and be sure to explore the many other tools we offer.
