About edit PDF metadata

Metadata is not only a liability to be stripped — set correctly, it makes a document findable and presentable. The Title field in particular does visible work: many readers display it in the window title and in browser tabs instead of the file name, which is why so many PDFs on the web are titled "Microsoft Word - final draft v3.docx". Document management systems, library catalogues, desktop search indexers and accessibility tools all read these fields, and a screen reader announcing a meaningful title rather than a file name is a genuine improvement. This tool writes the Title, Author, Subject and Keywords fields in the document information dictionary only. Any XMP packet is left untouched, so viewers that prefer XMP may still show the old values; a warning explains this after processing. Existing values are not prefilled into the input form. Fields left blank are preserved as they were, so you can correct one value without wiping the others; the result report shows the before-and-after values. Everything runs in your browser, and the page content is not touched.

How to edit PDF metadata

  1. 01

    Load the PDF

    Choose the document to edit. Existing properties are not prefilled into the form; use PDF Metadata Viewer first if you want to inspect them before changing anything.

  2. 02

    Fill the fields you care about

    Anything left empty keeps its current value. This editor cannot clear an individual field; PDF Metadata Remover clears the six supported information fields together, with its stated privacy limitations.

  3. 03

    Write a title that reads well

    Remember it may appear in a window title and be read aloud by a screen reader — write it for a human.

  4. 04

    Save the updated file

    Download the document with its new properties. Content and layout are unchanged.

What this tool does

  • Writes Title, Author, Subject and Keywords in the information dictionary; existing XMP properties are left untouched
  • Blank fields are preserved rather than cleared, so single-field corrections are safe
  • Shows before-and-after values in the result report rather than prefilling the input form
  • A meaningful title can help assistive technology identify the document, depending on the reader and any existing XMP metadata
  • Unicode-safe, so non-Latin titles and author names are stored correctly

Limitations worth knowing

Every PDF tool has constraints. Stating them plainly is more useful than discovering them halfway through your work.

  • Creator and Producer are not editable here — those record the software chain and are better left accurate.
  • Metadata carries no authority. Anyone can set an Author field to any name, so it asserts nothing.
  • Existing creation and modification timestamps are retained. Saving here does not automatically add or refresh a modification date.
  • Very long values may be truncated in some readers' property dialogs, though the full string is stored.

How your file is handled

This tool runs entirely inside this browser tab. When you choose a file, your browser reads it from your own disk and hands the bytes to JavaScript running on this page — no network request carries your document anywhere. You can confirm that yourself: open your browser’s developer tools, switch to the Network panel, and run the tool. You will see no upload.

Nothing is stored after the fact. Closing or reloading this tab discards the file, the result and everything derived from them, because none of it ever left your machine. Read how local processing works.

Questions about edit PDF metadata

Why does my PDF show a strange name in the reader's title bar?

The Title metadata field may contain the original source file name, and many readers use it instead of the current file name. Setting a proper title here updates the information dictionary. If a reader prefers an existing XMP title, it may still show the old value because this editor leaves XMP unchanged.

Does editing metadata change the visible document?

No. These fields live in the document properties, not on any page. Nothing in the layout, text or images is modified.

Do these fields help with search engine visibility?

Modestly. Crawlers indexing a PDF do read the Title and Subject fields, and a descriptive title is more useful in results than a file name. The document's actual text still matters far more.

Should I put my real name in the Author field?

That is a privacy judgement. For anything published, an organisation or team name is usually the wiser choice — it stays accurate and discloses nothing about an individual.
