How to edit PDF metadata online free

  1. Add your PDF: Drop the PDF. Its current title, author, subject and keywords fill in the boxes.

  2. Check the settings: Change what you like. Leave a box empty to remove that field.

  3. Save the result: Save. The Info dictionary and the XMP metadata are both updated, so every reader agrees.

Why it doesn’t upload

Changing a title shouldn’t require handing a whole document to a website. The PDF is read and rewritten in your browser tab, and nothing about it leaves your device.

Check it in your browser’s Network tab

Worth knowing

  • Only metadata changes: pages, text and images are copied as they are.
  • Dates are written in your computer’s time zone.
  • Digital signatures stop being valid after the file changes.

Under the hood

What happens to your file

Title, author, subject and keywords are written to both the Info dictionary and the XMP packet, because viewers show whichever is newer and editing only one leaves the old values showing somewhere. qpdf saves the file so replaced values do not linger inside it.

Why edit a PDF’s title and author?

The title stored inside a PDF is what browsers show in the tab and what search engines often show as the result’s headline — and for many files it’s “Microsoft Word - final_v3_JS.docx” or blank. Setting a proper title, author, subject and keywords makes your PDF look finished wherever it opens, and helps people find it.

Only the metadata changes. Pages, text and images are copied across untouched, and the whole job happens in your browser.

Common reasons to change PDF properties

  • PDFs published on a website

    Give each downloadable PDF a readable title so it looks right in search results and browser tabs.

  • Ebooks and reports

    Set the author and title that e-readers and document libraries display.

  • Correcting a template’s author

    Replace a colleague’s or a template designer’s name with yours or your company’s.

  • Document management systems

    Fill in subject and keywords so files are easier to search and sort.

  • Accessibility

    A title and language help screen readers announce the document correctly.

Tips for good PDF metadata

  1. Write the title for people: “Annual Report 2026 — Northfield Library”, not the file name.
  2. Set the language (en-US, fr-FR…) so screen readers pronounce the text properly.
  3. Keep keywords few and specific; they help internal search more than web search.
  4. To start from a clean slate, remove all metadata first, then set just the fields you want.
  5. Editing changes the file, so any digital signature becomes invalid — edit before signing.

Questions

How do I change the title of a PDF?

Drop it here, type the new title and press Save metadata. The title is also set to show in the reader’s window bar instead of the file name.

Why does my PDF show the wrong title in Google or a browser tab?

Browsers and search engines show the Title stored in the PDF’s metadata, not the file name. Setting it here fixes what they display.

How do I change the author of a PDF?

Replace the name in Author and save. Both places the author is stored — the Info dictionary and XMP — are updated, so no reader shows the old name.

Can I remove metadata instead of editing it?

Yes — leave the boxes empty, or use Remove PDF Metadata to strip everything including edit history in one go.
