Field	Location in PPTX	Risk
Author / Creator	docProps/core.xml	🔴 High
Company / Manager	docProps/app.xml	🔴 High
Last Modified By	docProps/core.xml	🔴 High
Speaker Notes	ppt/notesSlides/*.xml	🔴 High

1. Audit your PPTX

A PPTX is a ZIP archive. Core properties live in docProps/core.xml, app data in docProps/app.xml, speaker notes in ppt/notesSlides/.

# Copy first — never modify originals directly
cp "presentation.pptx" "copy.pptx"

# List all files inside
unzip -l "copy.pptx"

# View core properties (author, dates, last modified by)
unzip -p "copy.pptx" docProps/core.xml | xmllint --format -

# View app properties (company, manager, slide count)
unzip -p "copy.pptx" docProps/app.xml | xmllint --format -

# Check for speaker notes
unzip -l "copy.pptx" | grep notesSlide

# Check for embedded images with GPS
exiftool -G -a -s "copy.pptx" | grep -i GPS

2. Document Inspector

ℹ️

Fastest method — Document Inspector handles most metadata in one click — no extra tools required.

File → Info → Check for Issues → Inspect Document

Remove All for each category found

Open PPTX → File → Info → Check for Issues → Inspect Document.
Tick: Comments and Annotations, Document Properties and Personal Information, Invisible On-Slide Content, Presentation Notes.
Click Inspect, then Remove All for each found category.
File → Save As — save as a new file to preserve the original.

⚠️

Export speaker notes to a separate doc before removing if you still need them for rehearsal.

3. Remove speaker notes

Speaker notes are the most common source of sensitive leaks — draft text, internal strategy, presenter cues. Always remove before sharing publicly.

Via Document Inspector

Removes all notes in one click

Inspect Document → check Presentation Notes → Remove All.

Via PowerShell

Scriptable · batch-friendly

$pptx = "C:\docs\deck.pptx"
$ppt = New-Object -ComObject PowerPoint.Application
$ppt.Visible = [Microsoft.Office.Core.MsoTriState]::msoTrue
$pres = $ppt.Presentations.Open($pptx)
foreach ($slide in $pres.Slides) {
  $slide.NotesPage.Shapes[2].TextFrame.TextRange.Text = ""
}
$pres.SaveAs("C:\docs\deck_clean.pptx")
$pres.Close()
$ppt.Quit()

4. PowerShell automation

Full COM automation — clears built-in properties, comments, and speaker notes in one script. Requires PowerPoint installed on the machine.

# Full PowerPoint metadata cleanup via COM
$path = "C:\docs\presentation.pptx"
$ppt  = New-Object -ComObject PowerPoint.Application
$ppt.Visible = [Microsoft.Office.Core.MsoTriState]::msoTrue
$pres = $ppt.Presentations.Open($path)

# Clear built-in document properties
$props = $pres.BuiltInDocumentProperties
$clearFields = @("Author","Last Author","Company","Manager",
                 "Category","Keywords","Comments","Title","Subject")
foreach ($field in $clearFields) {
  try { $props.Item($field).Value = "" } catch {}
}

# Remove all comments
foreach ($comment in @($pres.Comments)) { $comment.Delete() }

# Clear speaker notes from all slides
foreach ($slide in $pres.Slides) {
  try { $slide.NotesPage.Shapes[2].TextFrame.TextRange.Text = "" } catch {}
}

# Clear custom properties
$custom = $pres.CustomDocumentProperties
for ($i = $custom.Count; $i -ge 1; $i--) {
  try { $custom.Item($i).Delete() } catch {}
}

# Save clean copy
$out = "C:\docs\presentation_clean.pptx"
$pres.SaveAs($out)
$pres.Close()
$ppt.Quit()
Write-Host "Done: $out"

ℹ️

For servers without Office installed, use ExifTool (section 5) for property fields. Notes and comments still need PowerShell COM.

5. ExifTool second pass

ExifTool reads and writes OOXML properties inside PPTX — ideal in CI/CD pipelines without Office installed.

# Clear common properties from a single file
exiftool -Title= -Subject= -Author= -Creator= -Company= -Manager= \
  -Keywords= -Comments= -Category= -LastModifiedBy= \
  -overwrite_original "presentation.pptx"

# Clear XMP metadata too
exiftool -XMP:All= -overwrite_original "presentation.pptx"

# Batch: clean entire folder recursively
exiftool -Title= -Subject= -Author= -Creator= -Company= -Manager= \
  -Keywords= -Comments= -Category= -LastModifiedBy= \
  -overwrite_original -r "./presentations/"

# Verify: check remaining fields
exiftool -G -a -s "presentation_clean.pptx" | \
  grep -iE "Title|Author|Company|Manager|Keywords|Subject|LastModifiedBy"

⚠️

Note — ExifTool cannot remove speaker notes or delete comments — use the PowerShell COM script from section 4 for those.

6. Embedded image EXIF/GPS

Photos inserted into slides retain their original EXIF metadata including GPS coordinates. These are stored in ppt/media/ inside the PPTX archive.

Option A — Clean before inserting

The safest approach. Strip EXIF from photos before adding them to slides.

✅

Use MetaRemover.com — drag and drop your photos, remove EXIF instantly in the browser. No upload, no tracking.

Option B — Strip from existing PPTX

# Extract, strip, and repack media files
mkdir pptx_media
cp "deck.pptx" "deck_work.zip"
cd pptx_media && unzip "../deck_work.zip" "ppt/media/*"

# Strip EXIF from all images in media folder
exiftool -all= -overwrite_original ppt/media/

# Repack into clean PPTX
cd .. && zip -r "deck_clean.pptx" pptx_media/ppt/media/

7. Verify cleanup

Always confirm all fields are actually gone before distributing.

# 1. Re-run Document Inspector — all categories should say "Nothing was found"

# 2. ExifTool cross-check
exiftool -G -a -s "presentation_clean.pptx" | \
  grep -iE "Title|Author|Company|Manager|Keywords|Subject|LastModifiedBy|XMP" \
  || echo "Common fields clear"

# 3. Unpack and inspect XML directly
unzip -p "presentation_clean.pptx" docProps/core.xml | xmllint --format -
unzip -p "presentation_clean.pptx" docProps/app.xml  | xmllint --format -

# 4. Check notes slides are empty
unzip -p "presentation_clean.pptx" "ppt/notesSlides/notesSlide1.xml" | \
  grep -o '<a:t>[^<]*</a:t>' | head -5

# 5. Check no GPS in media
exiftool -GPSLatitude -GPSLongitude "presentation_clean.pptx"
