How to Remove Hidden Metadata From a PDF (Free & Private, 2026)
You send a PDF and think you sent a document. You also sent your full name, the exact minute you last saved it, the version of Word or the printer driver you used, and sometimes the name of your company or the template it came from. All of it travels invisibly inside the file, and anyone who receives it can read it in a few clicks.
This hidden layer is called metadata, and it leaks more than people realise. This guide explains what your PDF is quietly telling people, how to check it yourself, and how to strip every trace of it for free, right in your browser, without uploading the file anywhere.
- Head to the Metadata Scrubber and add your PDF.
- Pick the Metadata Scrubber tool, which leads the list because it is the most useful one.
- Click Scrub Metadata and download the clean copy.
- Your original is untouched. The new file has no author, dates or software fingerprint.
What PDF metadata actually is
Think of metadata as a hidden label stitched into the file. It is not part of any page you can see, but the PDF carries it everywhere it goes. Some of it is harmless housekeeping. A lot of it is a quiet record of who you are and how you work.
There are two places it hides. The Info dictionary holds the classic fields: title, author, subject, keywords, the creator and producer software, and the creation and modification timestamps. Alongside it sits an XMP stream, a second block of metadata that programs like Adobe and Office use for richer details, edit history and application-private notes. Both travel inside the same file, and both are invisible until someone goes looking.
What your PDF is quietly telling people
The details sound minor one by one. Together they paint a surprisingly complete picture:
- Your name. The author field is usually your real name or your computer account name, set automatically the moment you created the file.
- Your software and version. Producer and creator fields reveal the exact app and version, which can hint at your operating system and even your employer's standard toolset.
- When you worked. Creation and modification timestamps show the precise date and time, which can quietly contradict a story about when a document was really prepared.
- Where it came from. Custom fields left by office software can include a company name, a template path, or the account of whoever last saved it.
- A trackable fingerprint. Every PDF has a document ID that can link one copy of a file back to the original you sent to someone else.
For a resume sent to a recruiter, an anonymous tip, a leaked-then-shared document, or a contract passed between parties, that hidden label can say far more than you meant to.
How to see the metadata in your own PDF
Before you clean a file, it helps to see what is in it. On most computers you do not need any special tool. On Windows, right-click the PDF, choose Properties, and open the Details tab. On a Mac, select the file and press Command plus I, or open it in Preview and choose Show Inspector. In Adobe Acrobat and most PDF readers, look under File then Properties. You will usually find the author, the software, and the dates sitting right there.
Seeing it is the moment most people decide to remove it. A resume that lists a previous employer's licensed software, or a personal document stamped with your full legal name, is not something you want travelling with the file.
How to remove every trace of it, free
The fastest way is the Metadata Scrubber, a free tool that runs entirely in your browser. It does not just blank the common fields, it wipes the whole hidden layer.
Step 1. Add your PDF
Open the tool and tap to add your file, or drag it in. Nothing is uploaded. The file is opened in your browser's own memory and stays on your device the entire time.
Step 2. Choose Metadata Scrubber
It is the first tool in the list, marked with a privacy tag. It clears the title, author, subject and keywords, the creator and producer software, the creation and modification dates, the entire XMP stream, application-private data, and the document ID fingerprint. Custom fields that ordinary tools leave behind, such as a company name or a last-saved-by account, are removed too.
Step 3. Download the clean copy
Click Scrub Metadata and save the result. Your original stays exactly as it was. Check the new file in Properties or Preview and you will see the fields are empty. The document reads identically, it simply no longer tells anyone who made it or when.
Metadata, redaction and passwords do different jobs
These three are easy to confuse, and using the wrong one leaves a hole:
- Scrubbing metadata removes the hidden properties around the file: who, what software, and when.
- Redacting permanently blacks out sensitive text on the visible page, so it cannot be copied or recovered.
- Password protection controls who is allowed to open the file in the first place.
A truly private document often needs more than one. Redact the visible secrets, scrub the metadata, and add a password if you also want to limit who can open it. Each step closes a different gap.
It all happens in your browser
There is a certain irony in uploading a private file to a stranger's server just to make it more private. The Metadata Scrubber avoids that entirely. The whole process runs on your own device, so the very file you are trying to keep quiet never travels anywhere. If you want that same privacy across other tools too, read our guide to Browser mode, which keeps dozens of PDF tools running fully offline on your device.
Frequently asked questions
What is metadata in a PDF?
Metadata is data about the file that is not part of the visible page. It typically includes the author name, the software that created and last edited the file, the exact creation and modification timestamps, the title, keywords, and sometimes application-specific fields like your company name or template path. None of it shows when you read the document, but any curious recipient can pull it up in seconds.
Can removing metadata be traced back to me?
No. Scrubbing happens on your own device and produces a clean copy. There is nothing to trace because the file never leaves your computer and the new version simply has no author, dates or software fingerprint attached.
Does deleting metadata change how the PDF looks?
Not at all. Every visible page, its text, images and layout stay exactly the same. Only the invisible properties are wiped. Open the scrubbed file and it reads identically, it just no longer answers questions about who made it or when.
Is removing metadata the same as redacting a PDF?
No, they solve different problems. Redaction blacks out sensitive text on the visible page. Metadata scrubbing removes the hidden properties around the file. If your document contains secrets in both places, you want to redact the visible content and scrub the metadata as two separate steps.
Will a password on the PDF hide the metadata?
No. A password stops people from opening the document, but once it is open the metadata is right there. Encryption and metadata scrubbing are unrelated. For truly private sharing, scrub the metadata first, then add a password if you also want to control who can open it.
Does the free scrubber leave a watermark or limit?
No watermark, ever. Without an account you can clean one file at a time up to 50 MB. A free account raises that to three files at once. The tool runs entirely in your browser, so there is nothing to meter.
Which metadata fields does the scrubber remove?
All of them. Title, author, subject, keywords, the creator and producer software fields, creation and modification dates, the XMP metadata stream, application-private data, and the document ID that can link one copy of a file back to another. What is left is a genuinely anonymous document.
