The data your PDF is carrying without telling you
Removing PDF metadata means stripping a hidden layer that has nothing to do with what's printed on the page — and if your document contains photos, that layer can include the exact GPS coordinates of where each picture was taken. Send a scanned contract, a property listing, or a portfolio, and you may be handing over your home address, your camera's serial number, your full name, the software you use, and a timestamp of every edit. None of it appears when you read the file. All of it appears in two clicks to anyone who receives it.
MiniPNG removes it at the root — not just the fields a PDF reader displays, but the data buried inside the embedded images, inside design-app leftovers, and inside the file's own identity fingerprint.
Location and camera data inside your photos
This is the part almost every other PDF metadata tool misses. A photo placed into a PDF keeps its own EXIF block: GPS latitude and longitude, camera make and model, lens, and serial number. Clearing the document's properties does nothing to it. Every embedded photo is cleaned individually.
Document properties and the XMP record
Title, author, subject, keywords, the application that created the file, the library that produced it, and the creation and modification timestamps. Modern PDFs also carry a second, richer record called XMP that duplicates these and adds an edit history — and it can attach itself to individual pages and images, not only to the document. All of it is hunted down, wherever it hangs.
The traces design and office software leaves behind
Illustrator, InDesign, and similar tools store private blocks inside PDFs that can name the workstation the file was made on. Comments and annotations carry the name of whoever wrote them along with timestamps. Files attached inside the PDF travel with it. Each of these is removed — though the text of a comment is kept, because that is content you wrote, not a fingerprint.
The identifier that links your copies together
Every PDF carries a pair of identifiers that tie one copy of a document to another, surviving even when everything else is cleaned. A fresh identifier is written so old and new copies cannot be matched.
Your file is rebuilt, not patched over
This is where most metadata removers quietly fail. Clearing a field by appending a correction leaves the original values sitting in the file — invisible in a PDF reader, and readable in seconds by anyone who opens it in a text editor. The document is rebuilt from the ground up instead, so the old values are physically gone.
Then it is checked. The cleaned file is re-opened and verified before you receive it. If anything survived, the job fails rather than handing you a file you believe is safe to send.
What is removed
- GPS location, camera make, model and serial number inside embedded photos
- Title, author, subject, keywords, creator and producer
- Creation and modification dates
- The XMP metadata record, at document and object level
- Private blocks left by design and publishing software
- Comment and annotation author names and timestamps
- Files attached inside the PDF
- The document identifier that links copies together
- Existing password protection, so the file opens freely afterwards
What is not removed
- Anything visible on the page — a name printed on a letterhead stays printed
- The text of your comments; only the name attached to them goes
What's next?
Cleaning a scanned document or portfolio? Remove Photo Metadata strips the same GPS and camera data from standalone images before you even build the PDF. Once your file is clean, Compress PDF can shrink it for sending, and Merge PDF can combine it with other cleaned documents — each source file's metadata stripped the same way.
