Add / Edit PDF Metadata

How to Edit PDF Metadata

1. Drop your PDF onto the tool, or click Choose PDF File.
2. Fill in the fields you want to set: Title, Author, Subject, and Keywords. Separate keywords with commas.
3. Check what is already there. The boxes open filled with the Title, Author, Subject and Keywords stored in the PDF. Edit what you need. A box you empty is removed from the file.
4. Click Update Metadata. A confirmation appears when the new properties are written.
5. Click Download PDF. The file is saved with _updated added to the name. If you change a field afterward, click Update Metadata again before downloading.

Why Use This PDF Metadata Editor

• Your file stays on your device. The PDF is edited by code running in your browser. Nothing is sent to a server.
• Pages are left alone. Only the document properties change. Text, images and layout stay exactly as they were, and text stays selectable.
• The fields people actually use. Title, Author, Subject and Keywords are what viewers, file managers and search tools read.
• Quick and reversible. Your original file is never touched, so you can edit again from the original any time.

Good to know: the boxes open with the values already stored in the PDF. Emptying a box removes that entry from the file. The Creator and Producer entries are left as they were, and the modification date is set to the moment you click Update Metadata. Some PDFs also keep a second copy of the title and author in an XMP block, which this tool does not edit, so a few readers may still show the old text. Password-protected PDFs will not open here, so use Unlock PDF first. To strip metadata instead, try Remove Metadata from PDF.
