Clear metadata tied to speaker notes and comments.
Ship client-facing decks safely
Deliver presentations without embedded workflow details.

Strip metadata & comments
We remove author/company fields, comments, revision data, and custom properties.
Preserve slides & media
Design, animations, and embedded media stay intact—only metadata is removed.

Download the cleaned PPTX instantly; the temporary copy is wiped immediately.
What PPTX metadata do we remove?
We clear PowerPoint properties that reveal authorship or workflow while keeping the deck unchanged.
- Author, company, manager, and last modified by fields
- Creation/modification timestamps and revision numbers
- Comments and metadata linked to speaker notes
- Subject, keywords, category, and description fields
- Custom properties stored in docProps/custom.xml
- Template and application/version identifiers
- Hidden slide/slide-part properties that carry editor details
- Embedded document IDs or relationships revealing provenance
Why PPTX decks leak more than DOCX files
PPTX uses the same OPC ZIP structure as DOCX but carries additional metadata surfaces that matter for client-facing presentation work. Every slide has its own XML part with per-slide revision markers, embedded media paths that can include the author's local file-system paths ('C:\Users\jdoe\Desktop\client-draft\logo.png' ends up literally in slide XML until you scrub it), and speaker-notes parts that usually contain commentary the presenter never meant to share with the client. Comments on slides are stored in commentAuthors.xml and comments/commentN.xml and persist through 'delete all comments' if the cleanup is done incorrectly.
PPTX presentations built from corporate templates carry the template's identifier and sometimes its origin URL in docProps/app.xml's Template field, along with 'HyperlinksChanged' flags that reveal whether outgoing links were modified. Embedded Excel charts are full XLSX packages inside the PPTX ZIP, each with their own author/company/revision metadata — and those are routinely missed by point-and-click scrubbers. Cleaning walks every package part, sanitizes docProps, removes comments/author-list/speaker-notes metadata, and recursively cleans embedded OLE objects without altering slide design, media, or animations.
