A journalist at a national newspaper sent a source a draft article for fact-checking. She exported it from Word as a PDF. The source opened it, went to File → Properties, and found her full name, her editor's name, the newspaper's internal template classification, and the fact that the document had been modified three times in 48 hours. None of that was in the article. All of it was in the metadata.
That kind of exposure happens every day, across every profession. Lawyers send contracts. HR teams send offer letters. Freelancers send proposals. Consultants send reports. Every one of those PDFs carries a hidden data layer the recipient can read without any special software — just three clicks in a free PDF viewer.
This guide covers exactly how to remove metadata from a PDF, using every available method, so you can choose the one that fits your workflow.
To remove metadata from a PDF: drop your file into FileIntel's PDF Metadata Remover — it strips the Author, Creator, Keywords, timestamps, and the XMP stream in under 5 seconds, entirely in your browser. For command-line users: exiftool -all= document.pdf. Saving or re-exporting does not remove metadata — you need a dedicated stripping step.
#1 What you are actually removing
Before you strip metadata, it helps to understand what you are stripping — because this is where most guides stop short and why "partial" removal fails.
Every PDF carries metadata in two separate stores. This is the fact that most people don't know, and it's the reason their metadata still shows up after they think they've cleaned the file.
Store 1: The Info dictionary. A key-value block embedded in the PDF's trailer section. Contains Author, Creator, Producer, Subject, Keywords, Title, CreationDate, and ModDate. Acrobat's Properties panel reads this.
Store 2: The XMP stream. An XML document embedded elsewhere in the PDF file body. Added by Adobe as a standard in 2001 and now part of ISO 32000. Contains the same fields as the Info dictionary, plus additional fields like dc:rights, xmp:CreatorTool, and revision history. ExifTool reads this. Most metadata "cleaners" don't touch it.
If you only clear the Info dictionary — which is what Acrobat's built-in cleaner and many online tools do — the XMP stream remains fully intact. Run ExifTool on that "cleaned" file and every field comes back.
Complete removal means stripping both stores. That's the standard we're working to here.
The fields above are real. The Manager field is the one that surprises people most. If you've ever used Office on a corporate machine, your company's Active Directory may have written your manager's name into your Office profile. That name has been silently stamping itself onto every document you've created and every PDF you've exported since.
To understand the full range of fields and what each one reveals, see our guide on what PDF metadata actually contains.
#2 Method 1 — Browser-based removal (fastest, no install)
This is the method most people should use. No software to install, no files uploaded anywhere, works on any OS.
Open FileIntel PDF Metadata Remover
Go to fileintel.me/pdf-metadata-remover. No account. No sign-up. The tool runs entirely in JavaScript inside your browser.
Drop your PDF in
Drag and drop or click to browse. The file is read into browser memory locally — nothing is transmitted to any server. You can verify this by opening DevTools → Network tab while the tool runs. Zero outbound requests carrying your file.
Read the Privacy Risk Score
The tool scores your file from 0–999 and shows every exposed field. Author gets 25 points. Manager gets 15. Keywords get 8. You see exactly what a recipient would find if they checked.
Strip and download
Click Strip Metadata. The tool uses a three-strategy approach: setter methods on the Info dictionary, direct deletion from the trailer dictionary, and full XMP stream removal. The result is a PDF with no recoverable metadata in either store.
Verify before you send
Open the output in Acrobat Reader → File → Properties → Description. All fields should be blank. The Producer field shows "FileIntel — fileintel.me" as confirmation the strip completed.

Free, private, browser-only. Nothing leaves your device. Works on any file size.
#3 Method 2 — ExifTool (command line, free)
ExifTool by Phil Harvey is the most trusted metadata tool in the world. It's free, open source, cross-platform, and used by digital forensics professionals. For stripping PDF metadata it works correctly and completely.
# Mac: brew install exiftool
# Windows: download installer from exiftool.org
# Linux: sudo apt-get install libimage-exiftool-perl
# Strip all metadata from a single PDF
$ exiftool -all= document.pdf
# Strip metadata and overwrite original (no backup)
$ exiftool -all= -overwrite_original document.pdf
# Strip metadata from all PDFs in a folder
$ exiftool -all= -overwrite_original *.pdf
# Verify the result — all fields should return blank
$ exiftool document.pdf
ExifTool Version Number : 12.76
File Name : document.pdf
Author :
Creator :
Producer :
ExifTool's -all= flag removes all metadata fields including the XMP stream. The default behaviour creates a backup file with _original appended to the name — which is useful if you want a safety copy but means you end up with two files. The -overwrite_original flag skips the backup.
One important limitation: ExifTool strips the Info dictionary and XMP stream, but it does not remove embedded document structure data like revision markers or incremental update sections. For most professional use cases, this is fine. For forensic-grade sanitisation in legal proceedings, a full PDF rewrite is needed.
#4 Method 3 — Adobe Acrobat Pro
If you have Acrobat Pro, the built-in sanitisation tools work for most cases but have known gaps. Here's the correct sequence — not just the obvious one.
Use Sanitize Document, not Remove Hidden Information
Tools → Redact → Sanitize Document. This is more thorough than "Remove Hidden Information." Sanitize performs a complete PDF rewrite, which destroys incremental update history and is more reliable at XMP removal.
Verify with ExifTool after
Even after Sanitize, run exiftool document.pdf to confirm the XMP stream was fully removed. Acrobat's Sanitize is thorough but has version-dependent behaviour on XMP stream removal.
Many users use "Remove Hidden Information" (the non-Sanitize option). This clears fields in the Properties dialog but often leaves the XMP stream intact. If you subsequently check the file with ExifTool, you'll see all the original metadata still present in the XMP fields. Always use Sanitize Document for complete removal, or follow up with ExifTool.
#5 Method 4 — QPDF (advanced command line)
QPDF is a free, open-source command-line tool that rewrites the PDF structure. Unlike ExifTool, which targets metadata fields, QPDF linearises and rewrites the entire file — which eliminates incremental update history, normalises the file structure, and often reduces file size.
# Mac: brew install qpdf
# Ubuntu: sudo apt install qpdf
# Rewrite PDF structure (removes incremental updates)
$ qpdf --linearize input.pdf output.pdf
# Combine with ExifTool for complete sanitisation
$ qpdf --linearize input.pdf temp.pdf
$ exiftool -all= -overwrite_original temp.pdf
$ mv temp.pdf output-clean.pdf
The QPDF + ExifTool combination is the most thorough free approach. QPDF handles structural sanitisation; ExifTool handles metadata field removal. Together they address every layer of the PDF that carries identifiable information.
#6 Which method for which situation
#7 What doesn't actually remove metadata
These are the methods people try first. None of them work for metadata removal.
| Method people try | Does it remove metadata? | What actually happens |
|---|---|---|
| Re-saving or exporting from Word | ✖ No | Adds new metadata — updates ModDate and may add additional Creator fields |
| Printing to PDF | ~ Partial | Loses some fields but often preserves Author and adds new Producer data from the print driver |
| Previewing on macOS and re-saving | ✖ No | Preview preserves existing metadata and adds its own Producer field identifying it as the last tool to touch the file |
| Acrobat "Remove Hidden Information" | ~ Partial | Clears Info dictionary but typically leaves XMP stream intact. ExifTool will still find metadata. |
| Converting to Word and back | ✖ No | Conversion adds your Office credentials as Author and Creator on the newly generated file |
| Changing file extension | ✖ No | The file contents are unchanged. Metadata is inside the file, not in the name. |
| Online tools (upload-based) | ~ Variable | Some work, most strip only the Info dictionary. Privacy risk: your document is uploaded to their server. |
#8 Understanding your Privacy Risk Score
FileIntel's PDF Metadata Remover scores every file before stripping. The score runs from 0 (no metadata) to 999 (maximum exposure). Here's how the weights break down:
#9 Why this matters for compliance
For EU and UK organisations, metadata removal is not just professional hygiene — it has a legal dimension under GDPR.
Under GDPR Article 5(1)(c), personal data must be "adequate, relevant and limited to what is necessary in relation to the purposes for which they are processed." An Author field containing an employee's full name is personal data under Article 4(1). Sending it to an external party in a document where it serves no purpose violates the data minimisation principle.
The UK's ICO has published guidance specifically noting that organisations sharing documents externally should check for and remove personal data in metadata fields. This applies to all file formats, not just PDF. See our detailed guide on GDPR and PDF metadata for the full compliance picture, or the UK GDPR vs EU GDPR comparison for post-Brexit specifics.
Make metadata removal a step in your document checklist, not an afterthought. Any PDF leaving your organisation — to clients, counterparties, regulators, media — should pass through a metadata check before it goes. The 30-second cost of checking is trivial against the risk of inadvertent disclosure. For freelancers specifically, our guide on metadata in proposals and contracts covers the professional implications in detail.
