Edit DOCX Metadata

1. 1

   Add a Word file

   Drag a DOCX, DOCM, DOTX or DOTM file onto the page, or press Browse. The tool reads the document's existing properties and fills every field with them.

2. 2

   Edit the properties you want to change

   Change the title, author, company, keywords, dates or any of the other 26 fields. Or press Strip all to empty every property, or Anonymise to clear only the ones that name a person or an employer.

3. 3

   Apply and download

   Press Apply. The tool writes the new values, re-reads the saved file with a second reader and shows you what changed, then hands you the updated document to download.

Every Word document carries a set of properties that travel with the file wherever it goes: who wrote it, which company they work for, what it is called, when it was created, how long it was edited for, and often a list of keywords. Windows Explorer shows them in the details pane. macOS shows them in Get Info. A document management system indexes them. A recruiter, a client or a journalist who receives the file can read all of them in two clicks. Editing Word metadata means deciding what that file says about itself before it leaves your hands - setting a real title so it is findable, adding keywords so it can be grouped, or removing an author name and a company name before sending a template to somebody outside your organisation.

What editing properties gets you

• A findable document: a real Title, Subject and Keywords make the file searchable in Explorer, in SharePoint and in every document system that indexes properties. A file called Document1.docx with no title is invisible to all of them.
• A clean handover: clearing Author, Last saved by, Company and Manager removes the four fields that most often reveal who produced a document and where they work.
• Correct attribution: a template passed between colleagues keeps the original author's name forever unless somebody changes it. Setting the Author is a one-line fix.
• Honest dates: Created, Modified and Last printed are editable here and untouched otherwise, so a document's history survives an edit to its title.
• Your own fields: custom properties store a client name, a matter number, a review status or a deadline alongside the document, and Word can insert them into the text as fields.
• A batch you can trust: one set of values applied across up to fifty documents, with every document's untouched fields left exactly as they were.

A Word file is a package of small parts, and the properties are not stored in one place. Knowing which part holds what explains why some editors only ever show you five fields, and why clearing the Author can leave a name in the document anyway.

The four places a name can hide

• Core properties: Title, Subject, Author, Keywords, Comments, Last saved by, Category, Content status, Revision number, Version, Language, Identifier, and the Created, Modified and Last printed dates. This is the part most online editors read, and for many of them it is the only one.
• Extended properties: Company, Manager, Application, Template and Total editing time, plus the statistics Word maintains - Pages, Words, Characters, Paragraphs and Lines. Word shows Company and Manager on the same dialog as Title and Author, so a tool that cannot see this part will happily tell you a document is anonymous while it still names your employer.
• Custom properties: your own named fields, with a text, number, date or yes/no value. This is Word's Custom tab. Documents produced by a document management system are often full of them.
• The document body: every tracked insertion, deletion and comment records the name of the person who made it, the person list records their email address, and each paragraph carries an editing-session identifier that links the file to one installation of Word. None of this is a document property, and clearing the Author does nothing to any of it.

This tool reads and writes all four. The property fields cover the first three; the personal-data controls in the settings panel cover the fourth.

Word's Properties dialog groups its fields into a summary block and an origin block, and this page uses the same names in the same order so that what you set here is what you will see there.

The summary fields

• Title: the document's real name, independent of its filename. This is what search and document systems display, and it is the single most useful field to fill in.
• Subject: a short description of what the document is about - a project, a client, a topic.
• Author: the person who wrote it. In the file format this is the creator field, which is what Word's Properties dialog labels Author. It is not the same field as Last saved by.
• Keywords: comma-separated tags. Word calls them Tags in some versions. Used for grouping and for search.
• Comments: a longer free-text note about the document, shown in the details pane.
• Last saved by: whoever saved the file most recently. Word rewrites this every time somebody saves, so it is frequently a different name from the Author and is often the one that gets forgotten.
• Category: a classification, such as Report, Contract or Minutes.
• Content status: where the document is in its lifecycle - Draft, In review, Final.

The origin fields

• Company and Manager: your organisation and the person responsible. Word fills Company in automatically from the installation, which is why so many documents quietly carry it.
• Application and Template: which program produced the file and which template it was based on. Both name the machine the document came from.
• Total editing time: how many minutes the document has been open for editing. Rarely useful and occasionally revealing.
• Revision number and Version: how many times the document has been saved, and a version label if one was set.
• Language and Identifier: the document's language tag and any external reference number.
• Created, Modified and Last printed: the three dates. Each has a Set to now button, and none of them is changed unless you change it.

Sending a document outside your organisation is the moment its properties matter most, and it is the moment they are least likely to be checked. Three presets cover the realistic cases, and each one states exactly what it does before you press Apply.

The three presets

• Anonymise: clears only the fields that identify a person, an employer or a machine - Author, Last saved by, Company, Manager, Application, Template, Total editing time and custom properties - and keeps Title, Subject, Keywords and the dates, so the document stays findable and its history stays intact. This is the right preset for almost every share.
• Strip all: empties every property including the statistics, and removes the custom properties entirely. Nothing is added back in their place: the tool does not stamp its own name into the Application field the way some editors do.
• Restore original: puts every field back to what the document arrived with, so you can experiment without having to reload the file.

Alongside the presets, two controls handle the part that lives in the document body: removing the author names from tracked changes and comments, and removing the editing-session fingerprints. The panel tells you how many names it found and lists them, so you are choosing to remove something specific rather than ticking a box on the off-chance. Both are Pro.

A Word file is an archive of small parts, and the properties live in three of them - docProps. Instead of taking the document apart and putting it back together, this tool reads only the index at the end of the file and the three small property parts it points at, then writes a new file whose other parts are carried across as the original's own bytes. That is why a hundred-megabyte document costs the same as a two-kilobyte one, and it is why the promise that nothing else changed can be checked rather than asserted: every part except the ones you edited is compared byte for byte in the test pack.

What happens when you press Apply

• Only the changed elements are rewritten: a field you did not touch is never visited, so it cannot be reordered, re-escaped or dropped. The elements that stay are the document's own characters, unchanged.
• Missing parts are created properly: if a document has never had a Company or a custom property, the parts that hold them are added along with the entries that make Word notice them. A part added without those is silently ignored, which is how a saved value disappears.
• The rest of the file is copied, not rebuilt: every other part comes across as the original bytes, so images are not recompressed and fonts are not re-embedded. The file size barely moves.
• The result is read back independently: a second reader, sharing no code with the one that wrote the file, opens the finished document and reports what it finds. The comparison you see is between the document you started with and the bytes you are about to download.

Reading a document's properties takes about two milliseconds whether it is two kilobytes or a hundred megabytes.

A few habits make document properties useful instead of an afterthought, and they take about ten seconds each.

Getting it right

• Set a Title on anything you will need to find again. Filenames get changed; titles travel with the file.
• Use Keywords as tags rather than as a sentence - comma-separated terms are what search indexes actually match on.
• Check Company and Manager before sending a document outside your organisation. Word fills Company in for you and almost nobody notices.
• Prefer Anonymise to Strip all when sharing: an empty title makes a document harder for the recipient to file, which helps nobody.
• Leave Created alone unless you have a reason to change it. A creation date is the most useful piece of provenance a file carries.
• Look at the verification panel after saving. It is showing you what is really in the file, and it takes a second to read.

Common use cases

• Sending a proposal to a client: Anonymise, then set the Author and Company to the values you want the client to see.
• Publishing a template: Strip all, so the template arrives with no trace of whoever built it.
• Filing a batch of exports: one Title, Subject and Category applied across fifty documents, each keeping its own dates.
• Preparing a document for review: remove the author names from tracked changes and replace them with a neutral label, so the review stays readable and anonymous.
• Fixing an inherited template: a document created from a colleague's file keeps their name as Author until somebody changes it.
• Adding matter or client references: custom properties store them alongside the document, where Word can insert them into the text as fields.

The numbers below are measured on this tool's own test suite, on a mid-range Windows laptop, and are printed on every run rather than estimated.

Measured on this tool

• Reading a document's properties takes about 2 milliseconds, and the number barely moves between a 2.6 KB file and a 105 MB one - the tool reads the index and three small parts, never the document.
• Writing takes under a millisecond on the same 105 MB document, because every part you did not edit is carried across as the original file's own bytes.
• 26 built-in properties are read and written, against the 5 the previous version of this page could see.
• Every part of the document except the ones you edited is compared byte for byte after every save, on 21 different file shapes.
• A full read and write makes zero network requests: the measurement is part of the test suite, not a promise in the copy.
• Four containers are supported - DOCX, DOCM, DOTX and DOTM - and every unsupported one is refused at the file picker with a message naming what to do instead.
