Edit PDF and document metadata

Why the author is so often wrong

Almost nobody types these fields in. They are filled in automatically from the account name of whoever was signed into the machine, or inherited from the template the document started as, and then carried through every export and every save afterwards. The result is that a PDF routinely credits someone who never worked on it — a colleague who left, a client whose template was reused, or the person whose laptop happened to produce the first draft.

It matters in three situations in particular. A CV or application that names a stranger looks careless at best. A tender or proposal that names a competitor, because their document was the starting point, is considerably worse. And anything submitted as independent work carries its own history in a field nobody thought to check.

What each file type stores

PDF keeps title, author, subject, keywords, the creating application, the producing library and two dates. Word, Excel and PowerPoint keep those plus "last saved by", the company, and the total number of minutes the file has been open — which is occasionally more revealing than intended.

Removing a field is emptying it

There is a real difference between leaving a field alone and clearing it. Emptying a value here removes the property from the file rather than setting it to an empty string, so the document stops carrying it at all. Fields you do not touch are left exactly as they were.

Nothing happens to the document itself

Only the properties change. A PDF is re-saved with its object graph intact rather than rebuilt, and an Office file is unpacked, has one small XML file edited, and is repacked with every other part carried across unchanged — a 35-part Word document comes back with all 35 parts. The pages, the formatting and the content are untouched.

Photos work differently and are handled on their own pages: a camera's EXIF is a packed structure whose offsets all reference each other, so it is safe to remove but risky to rewrite. See remove EXIF data for those.

Questions

What metadata does a PDF contain?

Title, author, subject, keywords, the application it was created with, the library that wrote the file, and the creation and modification dates. Most of it is filled in automatically by whatever produced the document, which is why it is so often wrong.

Why does my PDF have the wrong author?

Because the field usually comes from the account name of whoever was logged into the machine, or from the template the document started as. Exporting from Word, InDesign or a browser copies that through without asking. It is extremely common for a PDF to credit a person who never touched it.

Can I edit Word and Excel properties too?

Yes. Drop a .docx, .xlsx or .pptx and you can change the title, author, last saved by, subject, keywords, description and company. Office files store their properties as XML inside the package, which BriskFile rewrites and repacks exactly.

How do I remove my name from a document?

Empty the field and save. An empty value removes the property rather than leaving it blank, so the file stops carrying the name entirely. That is different from omitting the field, which leaves it as it was.

Does editing the metadata change the document?

No. The page content is untouched — only the properties change. A PDF is re-saved with its object graph intact, and an Office file is repacked with every one of its parts carried across unchanged.

Does Word keep a record of how long I worked on it?

It does. Office files store total editing time in minutes, and it is shown here alongside everything else. It is occasionally more revealing than anyone intends, particularly on something submitted as original work.

Is my document uploaded?

No. It is read, edited and rewritten by this page on your own device. That matters here more than for a photo: the documents whose author needs correcting are usually contracts, tenders, applications and reports — the last things anyone should be posting to a stranger’s server to change one field.

What BriskFile will not do to you

• Your files never leave your device

  Every conversion runs in your browser. Open DevTools, watch the Network tab, and you will see no upload — because there is not one.

• No account, no email, no watermark

  Nothing to sign up for and nothing stamped on your images. There is no step between choosing a file and getting it back.

• No limits at the download button

  No daily cap, no file counter, no "upgrade to download". If the tool starts a job, it finishes it.

• Checkable, not just claimed

  Open the Network tab and convert something — nothing goes out. Or load the page, disconnect, and watch it keep working: the tool is already on your machine, and your file never leaves it.
