the part nobody looks at
Every PDF carries a small block of document information: title, author, subject, keywords, and two fields naming the software involved. Word processors fill it in from your account, so the author of a file exported from a work laptop is usually a full name, and the producer often says exactly which version of which program made it. None of it appears on the page, and it travels with the file to everyone you send it to.
That block is also useful when it is right. A correct title is what a browser shows in the tab and what many document systems index instead of the filename — a report called "final_v3.pdf" whose title field still says "Untitled Document" looks unfinished in every list it appears in. So this tool does both jobs: fill the fields in properly, or empty them entirely, and either way the file is rewritten in your browser rather than being handed to a server.
three steps
The existing values are read out of the file and put into the boxes, so you can see what was there before you change anything.
Type over any field, or use the clear button to empty all six at once. Nothing is written until you save.
The PDF is rewritten with your values and downloaded. The pages themselves are untouched.
quick answers
Title, author, subject, keywords, creator and producer, plus creation and modification dates. Creator names the program the document came from, producer the one that wrote the PDF — often two different pieces of software, and often more specific than you would expect.
It empties those fields in the document information dictionary and the file is rewritten without them. Note that this is the standard metadata block only: a PDF assembled from other documents can carry additional structured metadata inside embedded objects, which no field editor reaches.
The pages are not touched. The file is parsed and written back out, so the byte layout differs and the size may shift slightly, but the content, fonts and links are the same.
Most libraries stamp their own name into it when they save. This one is explicitly told not to, because a tool whose job is clearing metadata should not be adding its own — whatever you type is what ends up in the file.
Not here. They are shown but read-only: the format has no way to express "no date", so a clear button would leave you with a wrong date instead of no date, which is worse than showing the real one.
No. The PDF is read, parsed and rewritten in your browser, which matters for exactly the documents whose author field you would want to check before sending.
