About PowerPoint PPTX Metadata Editor

Every PowerPoint deck carries a quiet manifest — author from your Office profile, company from your Office install, lastModifiedBy showing whoever last touched the file, plus extended properties about edit time, slide layout count and the template path. For an internal sales deck this is fine; for a client-facing pitch, a board presentation, a job-interview portfolio or a deck circulated under NDA, it's a privacy leak. PowerPoint's own Document Inspector covers it, but requires having PowerPoint installed and removes everything in one blunt sweep instead of letting you set, say, just the title to a specific value.

This PowerPoint PPTX metadata editor does the targeted version — view every property, edit any subset of the fields to specific values, and download a fresh .pptx with the new metadata baked in. 15 core fields (title, subject, creator, keywords, description, lastModifiedBy, revision, category, contentStatus, language, version, identifier, created, modified, lastPrinted) and 8 extended fields (Application, AppVersion, Company, Manager, Template, TotalTime, DocSecurity, PresentationFormat) are individually addressable. Fields are whitelisted server-side so a hand-crafted JSON payload can't inject arbitrary XML, and only docProps/core.xml and docProps/app.xml are touched — slide content, layouts, themes, embedded images, charts, speaker notes and TitlesOfParts / HeadingPairs (the OOXML slide-structure index) stay byte-identical.

Use it to anonymise a deck before sharing with a recruiter, sanitise a sales pitch before circulating outside the company, replace a placeholder author after a content-team handoff, scrub board-meeting decks for SEC disclosure, or clean up a template before publishing it to a downloads page. Files up to 50 MB.

PowerPoint PPTX Metadata Editor Use Cases

  • Sales teams scrubbing internal author and company names before client circulation
  • Job applicants anonymising portfolio decks before uploading to recruiters
  • Board secretaries cleaning meeting decks before SEC or regulator disclosure
  • Consultants replacing in-house author names with client names before delivery
  • Marketers stripping internal Company metadata from publicly-downloadable templates
  • Compliance teams auditing what hidden info sits in a deck before public release
  • Educators replacing placeholder author data with the right name after content handoff

PowerPoint PPTX Metadata Editor Features

  • Edit 15 core properties (title, subject, creator, keywords, description, lastModifiedBy, revision, language, dates) one at a time
  • Edit 8 extended properties (Application, AppVersion, Company, Manager, Template, TotalTime, DocSecurity, PresentationFormat)
  • Server-side whitelist on every field — hand-crafted JSON cannot inject arbitrary XML elements into docProps
  • Only docProps/core.xml and docProps/app.xml are touched — slides, themes, embedded images, charts, speaker notes stay byte-identical
  • TitlesOfParts and HeadingPairs (the OOXML slide-structure index) preserved verbatim so the slide-count summary stays accurate
  • Extract action shows the current values without modifying the file so you can audit before deciding what to change
  • Files up to 50 MB processed in a stateless serverless function and discarded immediately after the response

How to Use PowerPoint PPTX Metadata Editor

Upload your .pptx file

Drag-and-drop or click to select a PowerPoint .pptx file (up to 50 MB). Works on .pptx files from any PowerPoint version (2007 onward), Keynote export, Google Slides export and LibreOffice Impress — they all use the same OOXML container.

Extract to see current metadata

Click Extract. The current core and extended properties are read from docProps/core.xml and docProps/app.xml and shown in a table. The most common author leak comes from creator and lastModifiedBy; the most common company leak from Company and Manager.

Edit the fields you want to change

Type new values into the editable fields, or clear a value to remove it. Leave any field blank or unchanged to keep the original. Each field is independent — change author without touching the dates, or vice versa.

Click Update

The document is repacked with the new metadata and the slide content, themes, charts and speaker notes unchanged. The TitlesOfParts and HeadingPairs indices are preserved so PowerPoint's slide-count summary stays accurate in the rewritten file.

Download and verify

Download the rewritten .pptx. Open it in PowerPoint's File → Info pane, in Keynote, or in Google Slides to confirm the metadata changes landed. The slide content and rendering will be identical to the original.

PowerPoint PPTX Metadata Editor FAQ

No. Only the two XML parts docProps/core.xml and docProps/app.xml inside the .pptx package are rewritten. Slide XML files, themes, fonts, embedded images, charts, speaker notes and the TitlesOfParts/HeadingPairs slide-structure indices stay byte-identical to your upload. Open the rewritten deck alongside the original in PowerPoint and the slides render identically.

Core (15): title, subject, creator, keywords, description, lastModifiedBy, revision, category, contentStatus, language, version, identifier, created, modified, lastPrinted. Extended (8): Application, AppVersion, Company, Manager, Template, TotalTime, DocSecurity, PresentationFormat. Custom properties and comment authors are not currently exposed — for full inspector parity, use PowerPoint's built-in Document Inspector after this pass.

50 MB. This comfortably covers most decks including image- and chart-heavy presentations. Decks with embedded HD video can exceed 50 MB — either compress the embedded media in PowerPoint (File → Compress Media) first, or use python-pptx in a local script for arbitrary file sizes.

Document Inspector is all-or-nothing — it removes every category of personal info you tick and runs only inside PowerPoint. This tool is field-level: you can keep the Company name but change the Author, or replace the Manager without touching the dates. Useful when you want to set new metadata for the recipient (their name as creator) rather than wipe everything to defaults. Run Document Inspector afterwards if you also want to strip speaker notes, presentation comments and embedded personal data.

Yes. PowerPoint computes the slide-count summary that shows in File → Info from docProps/app.xml's TitlesOfParts and HeadingPairs blocks — both are preserved verbatim through the rewrite. Editing the creator or company name leaves the slide structure completely intact.

Yes, to a stateless serverless function — rewriting the .pptx package needs a real ZIP/XML pipeline that doesn't run cleanly in the browser. The file is deleted immediately after the response and nothing is logged to durable storage. For absolute paranoia, python-pptx (pip install python-pptx) does this locally in a few lines.

No — speaker notes and comments live in separate XML parts (notesSlide*.xml and comments*.xml) that are deliberately preserved here. If you also need to strip those before sharing externally, run PowerPoint's Document Inspector after this metadata pass, or use python-pptx to script the additional clean-up.

PowerPoint PPTX Metadata Editor Tutorial

Why edit PPTX metadata?

PowerPoint presentations carry hidden metadata: author name, company, last modified by, even the original template. When you share a deck with a client or post it online, all of that goes with it.

  • Privacy: Strip your name and company before sharing externally
  • Whitelabel: Replace internal author info with your client's name
  • Compliance: Finance and HR teams often require metadata cleanup before delivery
  • Forensics protection: Avoid leaking who edited a deck and when

How does it work?

A .pptx file is just a ZIP archive containing XML files. The metadata lives in docProps/core.xml (Dublin Core fields) and docProps/app.xml (Office-specific fields). This tool reads those XML files, lets you edit the values, and rebuilds the .pptx with the new metadata. Slide contents and structure are never touched — slide titles (HeadingPairs / TitlesOfParts) are preserved verbatim.

Editable fields

Core properties (Dublin Core):

  • title, subject, creator (author)
  • keywords, description (comments)
  • lastModifiedBy, revision
  • created, modified dates (W3CDTF)
  • category, contentStatus, language

Extended properties (Office-specific):

  • Application, AppVersion
  • Company, Manager, Template
  • TotalTime (minutes spent editing)
  • DocSecurity (0=none, 1=password, 2=read-only rec, 4=read-only enforced)
  • PresentationFormat (e.g. "Widescreen")

Slide titles, slide counts, and shared-doc flags are read-only — they're tied to the presentation structure and editing them would corrupt the file.
