About PDF Metadata Editor
This tool reads a PDF's document properties — title, author, subject, keywords, the creator application, the producer engine, and the creation and modification dates — and lets you edit any of them, then download the updated file. Pick a PDF and its current values load into the form so you can see exactly what's stored before you change anything.
Everything runs locally in your browser using the pdf-lib library. Your PDF is never uploaded to a server, so even sensitive documents stay on your device. Keywords are stored as a comma-separated list, and dates use your local time; leaving a field blank clears that property in the saved file.
One limit worth knowing: PDFs can carry metadata in two places — the classic Info dictionary and newer XMP packets. This editor writes the Info dictionary, which is what most viewers (including Adobe Reader and Preview) display in their Properties panel. It also cannot edit password-protected files; unlock those first.
Frequently asked questions
- What PDF metadata can I edit?
- Title, author, subject, keywords, creator (the source application), producer (the PDF engine), and the creation and modification dates. These are the standard document-info fields shown in a PDF viewer's Properties panel.
- Is my PDF uploaded anywhere?
- No. The file is read and rewritten entirely in your browser using pdf-lib. Nothing is sent to a server, so private or confidential documents never leave your device.
- Why don't my changes show up in some programs?
- Some PDFs also store metadata as XMP, a separate embedded block. This editor updates the classic Info dictionary that most viewers read. If a program is showing an old value, it may be reading the XMP copy, which this tool does not modify.
- How do I remove metadata instead of changing it?
- Clear a field and it will be blank in the saved PDF. Use the 'Clear all fields' button to wipe title, author, subject, keywords, creator and producer at once before downloading.
- Can it edit password-protected PDFs?
- No. Encrypted PDFs must be unlocked first. If you load one, the tool will tell you it's protected so you can remove the password and try again.
- Does editing metadata change the actual content of my PDF?
- No. Only the document-properties fields and dates are updated. The pages, text and images are re-saved unchanged.
