Edit PDF Metadata: Title, Author, Keywords
Metadata is the part of the document nobody edits and everybody sees: the title in the viewer, the author in the properties panel, the keywords in search.
What this tool does
Edits the document properties a reader sees in their PDF viewer: title, author, subject, keywords, creator, producer, creation and modification dates, plus custom fields.
How it works
Fill the fields you care about, add any custom pairs, and save. “Remove all metadata” strips the lot when a file must travel clean. This is the field set search engines and document managers read, so fixing the title here is worth doing before publishing a PDF on a site.
- Choose the PDF, or drag it onto the page.
- Set custom fields (add field) — the settings below explain what each one changes.
- Run the tool and download the result.
Settings that decide the result
- Custom fields (Add field) — One per line as Name = value.
- Title
- Author
- Subject
The remaining 6 controls stay on the tool page, where each one sits next to the live preview.
When to reach for it
- A published file shows Microsoft Word - untitled. Set the title and author properly before it goes out.
- Files need consistent keywords for a document system. Write them once per file, in one pass.
Questions we get
Which fields can I change?
Title, author, subject, keywords, creator, producer and the created/modified dates — plus custom fields of your own. Viewers, search engines and document managers all show this information.
Where it fits
The tools people usually open next to Edit Metadata:

- Grayscale — Make a PDF text and images grayscale
Every tool works on a copy, so the original file is never modified. Uploads are stored under an unguessable id and deleted automatically two hours after you last open them; nothing is listed, shared or indexed. More on the security page.
