PDF metadata is the information about the document rather than the page: title, author, subject, keywords, creator and dates. It helps a library or search engine describe the file, but it can also carry a name or software history you did not mean to share.
Step by step
-
1
Upload your PDF
Drag your PDF onto the box or click Choose file. It is sent over an encrypted connection and only used for this task.
-
2
Set the options
Adjust title, author, subject and keywords. Every field has a sensible default, so you can usually run the tool straight away.

3
Run it and download
Press Edit Metadata and the page shows progress while it works. When it finishes you get a download link — nothing is emailed and nothing is stored longer than it needs to be.
What the common fields mean
Title and author describe the document, not the file name. Subject and keywords are free text used by catalogues. Creator and producer often name the software that made the PDF; changing them does not change the file’s actual contents. Check the fields before editing so you know what is already there.
Remove all or edit selectively
“Remove all metadata” is the right choice for a clean outgoing copy or a privacy review. Editing individual fields is better when the document belongs in a catalogue and needs an accurate title and author. Custom fields can carry application-specific data; inspect them rather than assuming the standard five are the whole story.
Metadata is not redaction
Removing metadata does not remove text or images from the page. Conversely, redacting a page does not automatically clear the document’s title or author. For a sensitive release, do both: redact the content, then remove metadata, then verify the exported file in a second viewer.
Good habits for Edit Metadata
- The preview updates as you type, so you can judge spacing before running it.
- Leave a page range blank to apply to every page.
- Colours accept a hex value, so you can match an existing brand colour exactly.
Common questions
Is this tool free?
Yes. Every tool on this site is free to use, with no sign-up, no watermark and no daily task limit.
Do I need to install anything?
No. The tools run in your browser and are processed by this server.
What happens to my files?
They are stored under an unguessable id and swept automatically after a couple of hours. Nothing is shared or indexed.
Does it work on a phone?
Yes. The page pickers and editors are built for touch, so dragging, rotating and selecting pages all work without a mouse.
What does Edit Metadata do exactly?
Change PDF Author, Title, Keywords, Subject and other metadata fields
Does editing metadata change the PDF content?
No. It updates document information, not the pages. Redaction or page editing is a separate operation.
What hidden information can a PDF contain?
Author and software fields, XMP metadata, embedded attachments and comments are common. Remove metadata and inspect attachments separately if the document is sensitive.
Can I set a custom metadata field?
Yes. Add the field name and value in the custom-fields section; check the exported file to confirm the viewer displays it as expected.
