PDF Metadata Editor
Edit Title, Author, Subject & More

No. All processing happens entirely in your browser using JavaScript. Your PDF files never leave your computer and are never uploaded to any server. This makes the tool completely private and secure.

No. Metadata is separate from the document content. Your pages, text, images, and formatting remain completely unchanged.

You can edit the document title, author, subject, keywords, and creator application. The Producer, Copyright, and Creation date are set automatically when you save.

Click the "Clear All" button to remove all editable metadata fields. Then download the PDF with empty fields. Note that Producer and modification date will still be set when saving.

Creator is the original application that authored the content (like Microsoft Word). Producer is the software that converted or processed the PDF. When you edit with this tool, Producer is updated to show RJL.io PDF Tools.

Yes. The metadata is written using the standard PDF Info dictionary format, which is supported by all PDF readers including Adobe Acrobat, Chrome, Preview, and others.

Yes. Keywords in PDF metadata can be indexed by operating systems and document management systems, making your PDFs easier to find through search. Separate multiple keywords with commas.

This tool can open PDFs with viewing restrictions but cannot modify PDFs that require a password to open. You'll need to unlock the PDF first.

The edited PDF is downloaded as a new file - your original remains unchanged. If you need the original metadata back, simply use your original file.

Common reasons include removing personal information before sharing, adding proper attribution, improving searchability with keywords, meeting corporate standards, or updating outdated information in legacy documents.

There's no enforced limit since processing happens in your browser. However, very large PDFs (100MB+) may slow down your browser. For best performance, keep files under 100MB.
