PDF Metadata Editor
Change or remove a PDF’s title, author, keywords, dates and custom fields. The XMP copy is updated too, so every reader shows the same details.
Free · No sign-up · No watermark · Files stay on your device
What Does a PDF Metadata Editor Do?
A PDF metadata editor changes the hidden properties stored inside a PDF: title, author, subject, keywords, the apps that made it and its dates. PDFdukan reads every field, lets you rewrite or clear it, and saves a new copy in your browser without touching the pages.
PDFdukan also updates the XMP copy of these details, the second record many PDF readers check first. When we tested another free online editor, its saved file still carried the old title in XMP, so readers that check XMP showed the old title.
How to Edit PDF Metadata in 4 Steps
- Add your PDF. Tap Choose PDF or drop up to 20 files; current values fill the form.
- Change the fields. Type a new title or author, or empty a box to delete that value.
- Save the copy. Tap Save metadata; PDFdukan reopens the file to check the result.
- Download. Tap Download PDF, or Download all (ZIP) for several files.

When Should You Change PDF Properties?
- Before sending a resume built on someone else’s template
- When a report still shows “Microsoft Word - draft3.docx” as its title
- Before posting a PDF online, so search results show a real title
- When filing papers in a document system that sorts by author or date
Tips for Clean, Consistent Metadata
Keep “Also update XMP metadata” ticked, so every reader shows the same title. For a batch, set author and keywords on one file, tap Apply to all files, then give each file its own title.
Edit properties before you sign a PDF. Any change to the file afterwards makes the digital signature show as invalid, and PDFdukan warns you when a file is signed.
Is My PDF Uploaded?
No. PDFdukan edits the file with pdf-lib inside your browser tab, and restricted files are unlocked on your device with qpdf. Nothing is uploaded.
What This Tool Doesn’t Change
PDFdukan does not edit the text on the pages, file-system dates on your computer, or metadata inside images. A saved copy of a restricted PDF opens without its restrictions; use Unlock PDF to learn how those limits work.
