PowerPoint

Compress a PowerPoint

Almost every oversized deck is oversized for one reason: full-resolution photos nobody downscaled. This re-encodes the images inside your .pptx at the size they are actually shown, then rebuilds the file. Text, layout, animation and notes are copied across untouched.

Compress a deck

Photos are resampled to the width your slides actually show.

How to use it

  1. 01/03

    Drop the deck in

    The archive is opened and every embedded image is measured against the size it occupies on screen.

  2. 02/03

    Choose a quality

    Screen is right for anything projected or emailed. Print keeps more pixels for large-format output.

  3. 03/03

    Download the rebuilt file

    You get a before-and-after size, plus which images gave back the most.

Good to know

Why is my PowerPoint file so large?

Pasted photos keep every original pixel. A 12-megapixel phone photo carries roughly 24× more data than a 1920-wide slide can display, and ten of them push a deck past 50 MB on their own.

Will it visibly lower quality?

Images are resampled to the width they occupy on the slide and saved as high-quality JPEG. On a screen or projector the difference is invisible. For large-format printing, use the print setting.

What size does email allow?

Gmail and Outlook both stop at 25 MB per message and many corporate servers stop at 10 MB. Under 10 MB is the safe target.
