The Hidden Fingerprints on Your PDF Files
You might not know this. Every time you make a PDF or change it or even just save it some information gets added to the file that you cannot see. This is a fact. These hidden fingerprints, which are called metadata can show a lot of things about the file. For example the PDF can show what software you used to make it what kind of computer or scanner you used, when you made changes to it and sometimes even your name or what company you work for. When you look at the PDF it might look like it does not have any information but if you look closer you can find a lot of details about it. The PDF has a history that is attached to it. This history can be very detailed. Your PDF files have these hidden fingerprints. They can reveal a lot of things, about you and your computer.
When you share sensitive files like legal contracts, medical reports, or anonymous submissions, the last thing you want is for someone to snoop through your metadata. You've got this handled with our PDF Sanitizer. It acts like a digital eraser, meticulously stripping away all the hidden trackers, author dictionaries, and XMP streams. But the real highlight?
