Compress PPTX Online
A deck is slides of light XML wrapped around whatever screenshots, photos and video its author pasted in at full display resolution — and the media is the whole story again. This page shrinks what the slides carry without touching the structure, so the deck opens, animates and plays as built, at a fraction of the weight that made it impossible to email.

Frequently Asked Questions About Documents Compression
How do I shrink a PowerPoint file?
The media inside it, almost always: compressed pasted images and removed embedded video are where the weight lives. The slide XML itself is negligible.
Will the images look worse when projected?
At sensible settings, no — the display's own pixel count caps what anyone can see, and screen-sized images fill that cap.
Will my original file be changed?
The result is downloaded as a separate file. Keep your original until you have checked the Compressed PPTX.
What should I check before using the result?
Open the Compressed PPTX in the application that consumes it and spot-check the parts that matter to you; the original file stays untouched if you need to re-run with different options.
Is Compress PPTX Online free?
Yes. The compress PPTX is free with no trial limit, subscription, or watermark on downloads. Use it for personal and commercial projects without creating an account.
Are my files safe when I compress online?

Privacy and Security
FileCompress is built for trustworthy everyday use. When processing runs in your browser, files are not uploaded to our servers. When server-side compression is required for certain formats, transfers use encrypted connections and files are removed after processing according to our privacy policy.

Freelancers bookmark the compress PPTX because it removes the install-and-export cycle from traditional desktop compressors.

For PowerPoint decks ready for email and LMS uploads, compare file size in the results panel before downloading so you catch over-compression early.
