What is PPTX Tools?

PPTX Tools is a small client-side utility that cleans unwanted repeated embedded images from .pptx files.

Some exported presentations include extra images inside slides, slide layouts, or slide masters. Removing those manually can be annoying, especially when the same asset is repeated across many layouts.

This tool scans the internal PPTX structure and removes matching repeated layout assets while trying to preserve the actual slide design and full-slide backgrounds.

How it works

A .pptx file is basically a zip archive containing XML files and media assets.

PPTX Tools:

1. Opens the .pptx file locally using JSZip.
2. Reads slide, layout, and master relationship files.
3. Maps image references to their XML traces.
4. Detects repeated embedded image assets using file hashes.
5. Filters out full-slide background-like images.
6. Removes matching unwanted image references.
7. Rebuilds the .pptx file and downloads the cleaned version.

When it is useful

This tool can help when a presentation contains:

• repeated embedded layout images
• unwanted exported branding assets
• small repeated images inside slide layouts
• assets that are difficult to remove manually from PowerPoint

---

Limitations

This tool may not work for every PPTX file.

It currently focuses on repeated embedded image assets. It may not remove:

• text-based marks
• shapes drawn directly in XML
• watermarks baked into full-slide background images
• locked/protected presentation content
• unusual PowerPoint export structures

Always check the cleaned file before using it.
