PDF Metadata Editor

View and change your PDF's title, author, subject, and keyword information.

With PDF Metadata Editor, you just pick your file and download the result in seconds — no extra software needed. PDF Metadata Editor speeds up a step that often comes up right before sharing a PDF or moving it into another system. The whole process happens locally in your browser; nothing is sent to a server.

Step-by-step

Choose the document you want to edit in the PDF File field.
Fill in Title, Author and Subject with information that describes the document accurately. You can leave any field you don't want to change as it is.
Enter related terms in Keywords (comma-separated), for example: annual report, 2025, sales.
Click Save, then open the downloaded file and check the new values in your PDF reader's Document Properties window.

When is it useful?

When you publish a PDF on a website, browsers and search results may show the document's Title instead of its file name. Files exported from Word often arrive with an empty title or a meaningless one like Document1. The Author field can also carry the computer username of whoever created the file, which you may not want attached to a document you share on behalf of a company.

Example

Imagine a city council posting a tender specification on its website. Because the file came straight out of Word, the Title says draft_v3_final and the Author is a staff member's personal login. Change the Title to Park Landscaping Tender: Technical Specification, set the Author to the council's name, add a short Subject, and save. Anyone who downloads the file now sees clean, official details in the properties window.

What is metadata and why does it matter?

Separate from the pages, a PDF stores document information such as title, author, subject and keywords. Reader programs may show the title in the tab, and file managers and search tools can read this information. The tool only updates the fields you fill in and leaves the empty ones alone. You type keywords separated by commas, and the edited copy downloads as duzenlenmis.pdf.

Practical tips

Write the title as a readable phrase different from the file name; it may appear in the tab.
Before sharing, check that the author field does not carry a person or company name you do not want shown.
If the document covers one topic, put a short summary in the subject field.

Common mistakes

Expecting an empty field to erase the old value; empty fields are not changed.
Separating keywords with semicolons (the tool expects commas).
Thinking metadata alone is enough for privacy; it does not change information inside the document content.

Things to keep in mind

Metadata does not touch the document's content. A typo on page 3 can't be fixed here.
Fields like creation date or producing software are not part of this form; the tool only edits title, author, subject and keywords.
Stuffing the Keywords field won't lift a PDF in search rankings on its own. An accurate title does more than a long list of loosely related words.
Password-protected PDFs may refuse changes. Remove the protection first, then edit.
