Presentation privacy

A fresh start.
Every slide. Every image.

Upload a PowerPoint PPTX. Remove presentation properties and clean supported JPEG, PNG, and WebP images embedded across slides, layouts, and masters.

Presentation properties

Load the properties from your uploaded PPTX, then edit any values below. Blank fields are removed. Dates use UTC. Created and Last modified are separate properties; PowerPoint has no separate “last created” property.

Choose a PPTX to load its properties, or enter values manually.

Presentation cleanup

Existing properties, preview thumbnails, and package signatures are removed first. In editable mode, only the fields above are written back. PowerPoint may update metadata when you open and save the cleaned file.

Image cleanup removes supported EXIF/GPS, XMP/XML, prompt/workflow text, comments, and provenance blocks. JPEG orientation can remain. Unsupported or failed images are kept unchanged and clearly listed in the report. External image links are not fetched; embedded videos and documents are not cleaned.

Testing mode: original PPTX, cleaned PPTX, reports, ZIP, and job details are retained in individual storage/jobs folders until manually deleted. Metadata cleanup does not remove visible or pixel-embedded watermarks.

PowerPoint, Google Slides, and Keynote

Download a cleaned PowerPoint file (.pptx). You can open it in Google Slides or Apple Keynote and save a native copy there. This page does not create native Google Slides or .key files. Importing may change fonts, transitions, animation, or formatting.
