How does PPTX compression work?

PPTX files are ZIP archives. Our tool extracts the archive, re-encodes embedded images at optimized quality, removes unnecessary metadata, and repackages the presentation.

Will the presentation look the same?

Slide layout, text, transitions, and animations remain intact. Only embedded images are re-encoded. The presentation will look the same when opened.

How much can I reduce PPTX file size?

Presentations with many high-resolution images can be reduced by 50-90%. Text-heavy presentations see smaller reductions.

Is this PPTX compressor free?

Yes, completely free with no limits. Process as many PPTX files as you need, no registration required.
