About the PDF Metadata Editor
PDF Metadata Editor shows the hidden details stored inside a PDF and lets you change them. Open a file to see its title, author, subject, keywords, creator, producer and dates, edit any of them, and save a new copy. You can also remove all of the document's details, including the second XMP copy some programs add, before you share a file. It changes only the document's information fields. Text, names and dates printed on the pages are not touched, and other software may have stored similar data elsewhere. Everything happens in your browser.

What is hidden in a PDF
Every PDF carries a small record of facts about itself. The classic record holds a title, author, subject, keywords, the creating program, the program that saved it, and two dates. Some files add a second, richer record in XMP format with editing history and software details.
Most people never see this record, yet it travels with every copy of the file. That is useful for organising documents and awkward when it contains a name, a company or an old title you did not mean to share.
Editing title, author and keywords
A clear title helps in browser tabs, reading apps and search results. Fill in the author when you want credit, and add keywords to help you find the file later. Type keywords with commas or semicolons; the tool tidies them and stores them separated by spaces, as PDF viewers expect.
The modified date is refreshed by default when you save. Untick it if you want to keep the earlier date. Non-Latin text such as Japanese or Hindi is saved as Unicode, and if a character cannot be stored the tool warns you.
Removing metadata before you share
Ticking Remove ALL metadata clears every information field and deletes the XMP block, then saves a copy named with -clean. Use it before you post a PDF publicly, submit it anonymously, or send it to someone who does not need to know how it was made.
Open the cleaned file in a viewer and check the properties to confirm the fields are empty. Keep your original in case you need the details again.
What this tool cannot remove
Metadata is only one place where information hides. Names and dates printed on the pages, comment authors, embedded files, form values and your computer's own file dates are outside its reach. For text and images on pages, use Redact PDF. To make a form permanent, use Flatten PDF.
This is not a guarantee of anonymity. For a smaller file, see Compress PDF, and for a password, see Protect PDF.

Frequently asked questions
What is PDF metadata?
It is information about the document rather than its pages: the title, the author, keywords, the program that created it and when it was made or last changed. Viewers show it in the document properties, and search tools and file managers may read it.
How do I remove the author name from a PDF?
Open the file here and clear the Author box, or tick Remove ALL metadata to empty every field. Save, and download the new copy. Check the pages too, because a name printed in the text or in comments is not metadata and stays.
Why does the browser tab show a different title?
Many browsers display the title stored in the metadata, not the file name. If the title field is empty or wrong, the tab may show something odd. Set a clear title here and it will appear in most viewers.
Can metadata reveal personal information?
Yes. Author names, the software used, and creation and edit dates are often filled in automatically by whatever made the file. Before sharing a document publicly, look at these fields and clear what you do not want others to see.
Does this change the pages?
No. Only the document information fields are rewritten. The pages, fonts and images are carried over as they were, though the file is saved again, so its byte size can change slightly.
What are XMP and Info metadata?
Info is the classic small dictionary with fields like Title and Author. XMP is a newer XML block that many programs also add, often repeating the same details and more. This tool edits the Info fields and deletes the XMP block when you remove everything.
