Remove metadata from a PowerPoint

The pitch deck you’re about to send still names its author, the last person who saved it, your company and manager, how long you spent on it, when you last printed it, and where every photo on your slides was taken. Here’s how to remove metadata from a PowerPoint presentation, on Windows and Mac, comments and speaker notes included.

Short answer

PowerPoint metadata is the hidden information saved with a deck: author, last saved by, company, manager, dates, editing time, comments, speaker notes and the EXIF data of the photos on your slides. Three ways to remove it:

  1. Windows: File › Info › Check for Issues › Inspect Document › Inspect › Remove All for Document Properties, Comments and Presentation Notes.
  2. Mac: there’s no Document Inspector; clear Author, Company and Manager under File › Properties › Summary, then Review › Delete › Delete All Comments in This Presentation.
  3. Everything, photos included: open the PPTX in MetaClean and save a verified clean copy; your original stays as it was.

What metadata a PowerPoint presentation reveals

PowerPoint writes these details into every PPTX automatically, and anyone you send it to can read them under File › Info, or in Properties on Windows and Get Info on a Mac:

  • Author and last saved bySensitiveYour name, and the name of the last person who saved it.
  • Company and managerSensitiveFilled in from your Office account or your organisation’s template.
  • Photos on your slidesSensitiveEach image keeps its EXIF: GPS location, camera, serial number.
  • Comments and speaker notesSensitiveReview notes with names, and what you planned to say.
  • Editing time and revisionsRevealingTotal minutes spent editing and how many times it was saved.
  • DatesRevealingCreated, modified and last printed, to the second.
  • Hidden slidesRevealingSlides you skipped in the room still travel with the file.

You sent the pitch.It showed where you shot it,and who worked on it.

The photos on your slides carry their GPS location until something removes it.

How to use PowerPoint’s Document Inspector

PowerPoint for Windows has the Document Inspector built in. PowerPoint for Mac doesn’t, and unlike Word and Excel for Mac it has no option to remove personal information on save either, so there you clear the fields by hand:

PowerPoint for Windows

  1. Save a copy of the presentation first.
  2. Go to File › Info › Check for Issues › Inspect Document.
  3. Click Inspect, then Remove All next to Document Properties and Personal Information.
  4. Close the inspector and save.

PowerPoint for Mac

  1. Save a copy of the presentation first.
  2. Go to File › Properties › Summary and clear Author, Manager and Company.
  3. On the Review tab, choose Delete › Delete All Comments in This Presentation.
  4. Click OK and save.

What the inspector checks in each app, what to do on a Mac and why it can be greyed out: see the Document Inspector guide.

Remove comments and speaker notes from a PowerPoint

Comments and speaker notes are part of the slides themselves, so PowerPoint is the place to remove them. The Document Inspector does both in one pass:

  1. 1

    Open the Document Inspector

    File › Info › Check for Issues › Inspect Document, with Comments and Presentation Notes ticked.

  2. 2

    Remove them

    Click Inspect, then Remove All next to Comments and next to Presentation Notes. Every slide is cleared at once.

  3. 3

    Clean the rest in MetaClean

    Open the saved deck in MetaClean to remove the author, company and the location and camera details of every photo, and get a verified copy.

To delete the comments on one slide only, open the Comments pane and choose Delete All Comments on This Slide.

What PowerPoint’s own tools leave behind

The Document Inspector and the manual Mac steps clean the presentation’s own properties. Three things still go out with the file:

EXIF

Photos on slides

Every photo keeps its GPS location, camera model and serial number.

FILE

Your original

The inspector cleans the deck you have open, so the version with your details is gone unless you saved one first.

CHECK

No proof

Nothing confirms afterwards that every field is really empty, file by file.

That’s the gap MetaClean fills: it removes the presentation’s metadata and the photo metadata on every slide, from a copy, and checks the result.

How to remove all metadata from a PowerPoint

  1. 1

    Open the presentation in MetaClean

    Choose Documents › Single document and pick your PPTX or PPT file. It’s read on your computer; nothing is uploaded.

  2. 2

    See what it reveals

    A privacy warning lists the author, last saved by, company, manager, editing time and every other field, plus the details hidden in the photos on your slides. Comments and hidden slides are pointed out too.

  3. 3

    Choose what to remove

    The Privacy preset selects names, company and photo location and camera details. Tick anything else you want gone, field by field.

  4. 4

    Save the clean copy

    MetaClean checks that every selected field is gone and the slides are unchanged, then saves the copy in a “Clean” folder beside the original.

MetaClean for Windows inspecting Q4 Campaign Pitch.pptx: high-risk privacy warning “This document reveals sensitive details” with AI and Content Credentials, location in embedded photos, names and personal details and dates and software, the Privacy preset, and a Save clean copy button.
MetaClean shows what a deck reveals before you change anything: names, dates and software, and the photos on the slides.
MetaClean's Embedded images group for the photo on a slide: Content Credentials, lens model, camera serial number, GPS altitude, latitude and longitude, each selected for removal.
A photo on a slide keeps its own metadata: the camera’s serial number and the exact GPS location. MetaClean removes them without touching the picture.
MetaClean result for Q4 Campaign Pitch.pptx: Clean copy verified, saved as clean_Q4 Campaign Pitch.pptx. Removed: author Jordan Miller, last saved by Taylor Brooks, manager Alex Morgan, company Northwind Studio, and from the photo its Content Credentials, lens model, serial number and GPS location.
Every removal is checked in the saved copy: names, and the photo’s location and camera details.

Change the author in PowerPoint instead of removing it

Sending a deck under your company’s name rather than yours? In PowerPoint for Windows, go to File › Info, right-click the name under Related People › Author and choose Edit Property. In MetaClean, switch to Edit metadata to change the author, last saved by, company, manager and title at once, or clear any of them, and save a modified copy.

MetaClean's Edit metadata tab for a PowerPoint presentation: the author changed to Northwind Studio and the last saved by field cleared, with title, subject, keywords, dates, last printed date and revision number editable, and a Save modified copy button.
Edit metadata: here the author becomes the company name and “last saved by” is cleared, then a modified copy is saved.

Word documents, Excel workbooks and PDFs work the same way: see the guides for Word, Excel and PDF files. For photos on their own, use the photo metadata remover.

Your presentations stay on your computer

Pitches, board decks and client work shouldn’t pass through someone else’s server to remove a name. MetaClean works on your own Mac or Windows PC: no uploads, no account, no file size limits. More about privacy →

PowerPoint metadata: your questions

How do I remove metadata from a PowerPoint?

In PowerPoint for Windows, go to File › Info › Check for Issues › Inspect Document, click Inspect, then Remove All next to Document Properties and Personal Information, and save. PowerPoint for Mac has no Document Inspector, so clear the author, company and manager by hand under File › Properties › Summary, and remove comments with Review › Delete › Delete All Comments in This Presentation. To also remove the metadata inside the photos on your slides, and get a checked copy, open the PPTX in MetaClean and save a clean copy.

Where is the Document Inspector in PowerPoint?

In PowerPoint for Windows: File › Info › Check for Issues › Inspect Document. Tick what to check (comments, presentation notes, off-slide and invisible content, document properties), click Inspect, then Remove All next to each result you want gone. Save a copy first: its removals can’t be undone.

How do I remove comments from a PowerPoint?

On a single slide, open the Comments pane and choose Delete All Comments on This Slide. To remove every comment in the deck, use the Document Inspector: File › Info › Check for Issues › Inspect Document › Inspect › Remove All next to Comments. Then open the presentation in MetaClean to remove the author, company and photo metadata as well.

How do I remove all speaker notes from a PowerPoint?

Run the Document Inspector (File › Info › Check for Issues › Inspect Document) with Presentation Notes ticked, then click Remove All next to Presentation Notes. It clears the notes on every slide at once. Save a copy first if you want to keep a version with your notes.

What metadata does a PowerPoint file contain?

The author, last saved by, company and manager, title, subject and keywords, created, modified and last printed dates, the revision number and total editing time, comments with their authors’ names, speaker notes, hidden slides, and the EXIF data of every photo on your slides, including GPS location and camera serial number.

How do I change the author in PowerPoint?

In PowerPoint for Windows, go to File › Info, right-click the name under Related People › Author and choose Edit Property. In MetaClean, open the presentation, switch to Edit metadata, type the new author (your company name, for example) and save a modified copy. Last saved by, company and manager can be changed or cleared the same way.

Does removing metadata change my slides?

No. MetaClean edits only the metadata fields you choose and copies every slide, layout, image and animation unchanged, then reads the copy back to confirm it. Photos are cleaned without being recompressed.

How do I remove metadata from many presentations at once?

Drop the folder into MetaClean’s Documents › Batch folder: it cleans every PPTX, PPT, DOCX, XLSX, PDF and OpenDocument file inside, subfolders included, and saves verified copies.

Does this work for Word and Excel too?

Yes. Word documents and Excel workbooks store the same author, company and date metadata, and MetaClean cleans DOCX, DOC, XLSX and XLS files the same way, plus PDF and OpenDocument ODT, ODS and ODP.

Send the deck.
