POWERPOINT + PPTX METADATA REMOVER
Remove metadata from a PowerPoint presentation
A PowerPoint file can reveal its creator, last editor, organization, timestamps and contributor identities. KillMetadata removes supported package metadata from a rebuilt PPTX copy without uploading the presentation.
THE CLEANING PLAN
Remove what exposes you. Keep what makes the file work.
Every field is shown before the rewrite and classified by action and coverage.
- Slides, layouts, themes and speaker notes
- Images, audio, video and embedded media
- Transitions and animations
- Accessibility labels and presentation structure
- Sensitive text visible on slides or notes
- Hidden slides and off-canvas objects
- Embedded workbook contents
- PPTM macros, encryption and password protection
WHY THE ENGINE MATTERS
The presentation stays a valid OOXML package
PPTX stores slides and properties in related XML parts inside a ZIP container. The handler cleans known property and attribution parts, resets package timestamps, and passes slide and media entries through.
Speaker notes and hidden slides can contain private content, but deleting them would change the presentation. They stay intact and are listed as a separate pre-sharing review task.

QUESTIONS, ANSWERED
Know the boundary before you clean.
No vague “100% clean” claim.
Are my files uploaded?
No. The cleaner runs in your browser, has no upload endpoint, and only enables the file picker after its processor assets are available locally.
Is the original file changed?
No. KillMetadata reads the original and creates a separately named cleaned copy. It never overwrites the source file.
Are speaker notes removed?
No. Speaker notes are presentation content. Review or remove sensitive notes in PowerPoint before sharing.
Will animations and embedded media remain?
Supported slide, animation and media entries are preserved. Open the saved copy and test playback as a final content check.
