Compress PowerPoint online
Shrink a .pptx presentation that's grown large with images.
Presentations get heavy fast — every full-resolution photo, screenshot and chart image adds up. This tool re-compresses the images embedded in your .pptx so the file becomes much smaller, while your slides, text and layout stay the same. It's the quickest way to get a deck under an email or upload limit.
Image-heavy decks shrink the most; a slide deck that's mostly text and shapes has less to remove. Set a quality preset or aim for a target size. Files are processed privately and deleted right after.
Frequently asked questions
Will my slides or animations change?
No — only embedded raster images are re-compressed. Text, shapes, layout and transitions are preserved.
How much smaller will my deck get?
It depends on how image-heavy it is. Decks full of photos and screenshots often shrink dramatically; mostly-text decks change little.
Does it work on embedded video?
The tool focuses on images, which are the usual cause of large files. Very large embedded videos are better compressed separately with a video tool before inserting.
Is it safe and private?
Your file is uploaded over HTTPS, processed on our server, and the upload is removed right after. The generated result is cleaned up automatically by a periodic job. We never share your files and no account is needed. See our Privacy Policy.
