To remove metadata from a PDF on Windows or Mac, open the file in Adobe Acrobat, go to File then Properties, clear each tab and save. For batch cleaning across many files at once, use PCDOTS Metaraser to scrub author, title, producer, and hidden properties in one click.
PDF files carry hidden data inside every document. This hidden layer is called metadata. It stores the author name, software used, creation date, edit history, and the PDF producer string. A clean PDF should not leak this information when you share it with clients or post it online.
This guide shows how to remove metadata from PDF files on Windows, Mac, and Adobe Acrobat. It also covers bulk cleaning, free and online routes, and what to watch out for when you scrub PDF properties.

What Is PDF Metadata
PDF metadata is descriptive data baked into every PDF file. It records the author, title, subject, keywords, creation date, modification date, and the application that produced the file. Most readers like Adobe Acrobat, Foxit, and Preview show this data under File then Properties.
At a glance
Common PDF metadata fields include Author, Title, Subject, Keywords, Created, Modified, Application, and PDF Producer. Hidden data may also include comments, form data, attachments, and bookmarks.
Why Remove Metadata from a PDF
Metadata leaks personal and business details. A PDF shared with a client may reveal the author username, your office software, and timestamps that show when the file was edited. For privacy, compliance, and clean publishing, you should clear metadata before you send or upload any PDF.
- Protect author identity and team usernames.
- Remove company device names and software versions.
- Strip edit history and hidden comments.
- Meet GDPR, HIPAA, and other privacy rules.
- Stop competitors from reading file production data.
How to Remove Metadata from PDF in Adobe Acrobat
Adobe Acrobat lets you edit and clear PDF properties one file at a time. Use this route for a single document.
Adobe Acrobat DC and Pro DC
- Open the PDF file in Adobe Acrobat DC.
- Click File then Properties.
- Open the Description tab and clear Author, Title, Subject, and Keywords.
- Open Additional Metadata and click Advanced.
- Select each item under XMP and click Delete.
- Click OK and save the file.
Adobe Acrobat X and XI
- Open the PDF in Adobe Acrobat X.
- Choose Tools then Protection then Remove Hidden Information.
- Tick Metadata and any other items you want gone.
- Click Remove and save the cleaned PDF.
Watch out
Acrobat clears only the file open on screen. If you have hundreds of PDFs, this manual route takes hours and leaves room for human mistakes.
How to Remove Metadata from PDF on Windows
Windows users have three common routes: Adobe Acrobat, the built-in File Explorer Properties dialog, or a desktop bulk cleaner like PCDOTS Metaraser.
- Adobe Acrobat: best for single files with full XMP control.
- File Explorer: right-click the PDF, pick Properties, open Details and click Remove Properties. Windows can only strip a small set of fields here.
- PCDOTS Metaraser: best for bulk cleaning on Windows 10 and Windows 11. It strips author, title, producer, and hidden XMP across hundreds of files in one pass.
How to Remove Metadata from PDF on Mac
On macOS you can use Preview for a quick clean or Adobe Acrobat for deeper control. Preview shows only basic fields, so Acrobat is the safer pick.
- Open the PDF in Preview and pick Tools then Show Inspector.
- Click the (i) tab and review the visible metadata fields.
- For full control, open the file in Adobe Acrobat on Mac and use the steps above.
- For bulk cleaning on Mac, export PDFs to a folder and run PCDOTS Metaraser on Windows or through Parallels.
How to Remove All Metadata from PDF in Bulk
Bulk metadata removal is the right approach when you handle PDF folders for legal, design, or publishing work. Manual cleaning is slow and prone to gaps.
PCDOTS Metaraser reads every PDF in a folder, lists every metadata field, and clears them in one batch. It keeps the page content intact and only removes the descriptive layer.
Load PDFs into the cleaner
Launch PCDOTS Metaraser and click Add Files or Add Folder to load every PDF you want to clean.
Pick metadata fields to remove
Tick Author, Title, Subject, Keywords, Producer, Creator, Created, Modified, and any custom XMP fields you want erased.
Choose an output folder
Set a clean folder so original files stay untouched. The app writes cleaned copies into the chosen path.
Run the batch and verify
Click Start and wait for the run to complete. Open one cleaned file in Acrobat and confirm File then Properties shows empty fields.
Clear PDF Producer and Hidden Properties
The PDF Producer field tells anyone reading the file which software wrote it. Common values include Microsoft Word, LibreOffice, Adobe Acrobat, and Chrome. Many users want this string cleared before public release.
Hidden PDF properties also include comments, attachments, form data, and bookmarks. A full clean strips all of these in one pass.
Pro tip
After a bulk clean, drop one file into an online PDF inspector and check that Author, Producer, and XMP are empty. A second check catches any field your method missed.
Online and Free Methods: A Warning
Online PDF metadata removers ask you to upload private documents to a server you do not own. Free desktop tools may bundle adware or leave the XMP packet partly intact.
Privacy risk
If your PDFs hold client data, finance reports, or legal drafts, do not upload them to a free online site. Pick a paid desktop option like PCDOTS Metaraser that runs on your machine and never sends files to the cloud.
Key Takeaway
Pick Acrobat for one-off cleaning. Pick PCDOTS Metaraser for bulk cleaning on Windows. Avoid free online uploads when files hold private or business data.
The Conclusion
We covered every clean path: Adobe Acrobat DC, Acrobat X, the Windows File Explorer trick, macOS Preview, and the bulk route with PCDOTS Metaraser. The manual routes work for single files. The bulk route is the only safe pick when you handle folders of PDFs.
Pick the method that matches your file count and your privacy needs. Always verify the cleaned file in Acrobat to confirm every field is blank.
