PPTX Lightweight Compression · Local-only

Free Online Lightweight PPT Compressor

Lightweight PPTX compressor that repacks the underlying ZIP container locally in your browser, trying to reduce size without touching slide content. It does not recompress images or media, so size reduction is not always guaranteed.

Note: This tool performs a “lightweight” compression by repacking the PPTX ZIP container. It does not parse or recompress images/media, so file size may not always shrink. Best used as a quick pre-share repack.

Pick a PPTX file, adjust compression level, and export.

Tips

The tool only repacks the PPTX container and does not modify slide content or layout.
If the deck is dominated by high-resolution images or videos, large reductions are unlikely.
Everything runs locally in your browser with zero uploads.
