Edit PDF Metadata
Edit PDF metadata: drag in a file, change the title, author and other details or remove everything, save. The file is processed in your browser and never uploaded.

How it is calculated
In short: Every PDF carries details about itself: title, author, subject, keywords, the program that created it and dates. This tool shows them, lets you change them or remove them all. The pages stay unchanged and everything runs in the browser.
How it works
- Drag in or choose a PDF. The existing details appear in the fields.
- Change the fields. An empty field deletes the detail from the file.
- “Save metadata” creates a new PDF. “Remove all metadata” deletes everything, including the dates.
What metadata is for
- Title: browsers and PDF programs show it in the tab or window instead of the file name. Search engines often use it for the search result too.
- Author and producer: they reveal who wrote the file and with which program it was made. When you pass on a PDF you sometimes want to remove that.
- Keywords and subject: help with sorting and finding files in document management.
Honest limits
- Only the document information is changed. Text, comments, hidden layers, attachments and the document ID stay as they are.
- An existing XMP data block is removed on saving so that it does not contradict the new details.
- Encrypted or damaged PDFs cannot be edited.
- The tool adds nothing of its own: producer and creator are exactly what you enter.
Privacy
The PDF is processed only in your browser and is not uploaded.
