PDF Metadata Editor
Update document details without changing the visible page content or converting the PDF into images.
What is PDF metadata?
Metadata is information stored with the file, such as title, author, subject, keywords, creator application, producer and dates. It may appear in a PDF reader’s properties panel and can help identify a document even when the file name changes.
When should metadata be reviewed?
Check it before publishing, sending client documents, sharing templates or reusing a PDF created by another application. Old author names, internal project titles or software details can remain in a file even when they are not visible on the page.
What this editor does not change
- Page text, images, fonts and layout remain untouched.
- The tool does not remove attachments, comments or hidden layers.
- Changing metadata does not prove authorship or ownership.
- Password-protected files may need to be unlocked by an authorized user first.

Review page count, first-page dimensions and source file size before editing.
Clear author, creator, producer, keywords and date fields in one step.
Metadata is saved without rendering, compressing or rebuilding the page artwork.
How to edit PDF metadata online
- Choose a PDF and review the metadata fields: document title, author, subject, keywords, creator application, producer and dates.
- Edit only the fields you need. Clear a text field to remove its value, or open the Privacy clean tab and use Clear all personal metadata fields before sharing a file publicly.
- Leave fields unchanged when you want to preserve their current values.
- Open the Output tab, click Save metadata & download, then check the new copy’s document properties to confirm the changes.
Before sharing, follow the checklist on how to remove PDF metadata before sharing and the wider PDF privacy and security guide.
Who this metadata editor is for
It is for anyone who publishes or sends PDFs and wants the hidden document details to be correct: freelancers reusing an old proposal, teachers sharing worksheets made from a colleague's template, small businesses posting price lists, and job seekers sending a CV that still carries an old author name. It changes the file's properties only, so the pages look exactly the same.
A worked example: a proposal made from an old template
Open proposal.pdf and look at the current fields. Suppose the Title says "Template v3 – internal", the Author shows a former colleague, and the Keywords field lists an internal project code. Change the Title to "Website redesign proposal – Asha Designs", set the Author to your name, delete the Keywords, and leave the dates alone. Save and download, then open the new copy's document properties in your PDF reader to confirm the new values before you send it.
Common mistakes to avoid
- Assuming metadata is the only hidden data. Comments, form fields, attachments and layers need a separate check.
- Expecting printed names to change. A name typed on the page stays there; use Redact PDF for visible text.
- Stuffing the keywords field. Keep it to a few honest terms that help you find the file later.
- Treating dates as proof. Creation and modification dates can be edited and are not evidence of when a document was written.
Frequently asked questions
Will editing metadata change the visible PDF pages?
No. The tool updates document properties and saves a new PDF without rasterizing or redrawing the pages.
Can I remove an old author name?
Yes. Clear the Author field and save the new copy.
What should I put in the keywords field?
Use a short comma-separated list that helps your own document management. Avoid adding confidential internal terms to public files.
Are metadata dates always reliable?
No. Creation and modification dates can be changed by software and should not be treated as proof of when a document was authored.
Does this remove all hidden information?
No. Metadata is only one source of hidden information. Comments, form fields, attachments and layered content require separate review.
Is the PDF uploaded?
No. Metadata is read and written locally in your browser.

Review PDF metadata before sharing: an old author or title may remain from an earlier template. Clearing metadata does not remove names printed on the pages or replace a full privacy review.
🔒 Privacy: the tool processes files in your browser. Your document is not uploaded to LyfPDF.
Metadata is the hidden label, not the page text
The metadata editor reads and writes document info such as title, author, keywords and dates. It does not rasterise pages, so the visible PDF and its selectable text stay. Clearing the info dictionary does not remove text that is written on the page, a watermark, a comment stuck to a sentence, or a hidden attachment. Those need the editor, redaction, or a full rebuild.
Do this before you send a CV, a contract draft, or a file exported from Word that still says “Author: your personal name”. After saving, open the file in a second viewer and look at its properties. If a portal rejects the file, the cause is often encryption or a form, not the title field.
