## About

PDF Metadata Editor reads and rewrites the Document Information Dictionary — the properties every PDF viewer shows under File → Properties. Set a proper title (the one browsers use for the tab and search engines for the snippet), name the author, add a subject, or list keywords.

It also cleans the creator string left behind by whatever tool generated the file. Edits are saved back into the PDF locally; the file never leaves your device.

## How to use

1. **Choose the PDF** — Current properties load into the form.
2. **Edit the fields** — Title, author, subject, keywords, creator, producer.
3. **Save** — A new PDF with the updated properties is downloaded.

## FAQ

### Which fields can I edit?

The standard Info-dictionary fields: title, author, subject, keywords, and creator — plus the modification date, which is refreshed automatically. The Producer field is shown for reference but is re-stamped by the processing library on every save.

### Does this remove hidden metadata too?

It rewrites the visible properties panel. Attachments, annotations, and revision history are separate structures — use Flatten PDF for form/annotation content, and re-derive sensitive documents from source if that matters.

### Can I blank a field completely?

Yes — clearing a field and saving writes an empty value, which viewers display as unset.

### Why does the Producer field not stick?

pdf-lib, the in-browser library that rewrites the file, writes its own producer string during every save. Editing Producer would be silently undone, so the tool labels it as informational rather than pretend to change it.

### Why does the browser tab still show the old title?

Viewers may cache properties until the file is reopened. The saved PDF carries the new title; re-download or reopen it to see the change.
