Edit PDF Metadata

Four standard document Information dictionary fields: title, author, subject, and keywords. These are the properties most viewers show under document details, and the ones most people need to correct or clear.

No. The file is read and rewritten entirely in your browser with the pdf-lib library. The bytes never leave your device, so contracts, invoices, and other confidential documents stay private.

Type them in one box separated by commas, for example invoice, 2024, tax. Each comma-separated entry is trimmed and saved as its own keyword, and blank entries from stray commas are dropped. The live counter shows how many keywords will be written.

Yes. Click Clear all to blank every field, then Save and download. That writes empty title, author, subject, and keywords into the Info dictionary, which is useful before publishing or sharing a file more widely.

No. Only the document information fields are rewritten. The pages, text, images, and layout are untouched, so the visible document looks identical to the original.

This tool edits the classic Info dictionary. Many PDFs also embed an XMP metadata packet, and some viewers read title and author from there instead. XMP is not modified here, so a separate inspector may still show those older values.

Not with this tool. It focuses on the four common fields. Creation and modification dates, the producer and creator strings, and any custom properties are outside its scope, and note that saving with pdf-lib may refresh some of those automatically.

If the file is encrypted or corrupted the reader shows an error and cannot load it. Remove the password in a PDF reader first, then bring the unlocked copy back here to edit its metadata.

To avoid overwriting your original, the tool inserts a -metadata suffix before the extension, so report.pdf downloads as report-metadata.pdf. You can rename it afterward.
