Edit PDF Metadata

View and change a PDF's title, author, subject, keywords, creator, producer, dates and language — written to both the document information and the XMP metadata, so every app shows the same. Runs entirely on your device.

About this tool

Edit PDF Metadata — Title, Author, Keywords and Dates

See and change what a PDF says about itself: title, author, subject, keywords, creator, producer, dates and language. Everything runs locally in your browser — no upload, no sign-up, no watermark and no file size limit.

Both Metadata Places in Sync

A PDF keeps its properties twice: in the document information that older apps read and in the XMP metadata that newer ones read. Toolula shows both, says where they disagree and saves every field to both, so every viewer, search engine and archive sees the same title.

Every Script, Exact Dates

Titles and names in any language — umlauts, Chinese, Japanese, Arabic — are stored as Unicode, and dates keep their time zone. Choose whether the modification date becomes now, and whether viewers show the title instead of the file name.

Safe With Signed and PDF/A Files

PDF/A identification is kept and both metadata places stay identical, as the standard requires. A digitally signed file is flagged before you save, because any change invalidates the signature; password-protected files are sent to Unlock PDF first.

How to use it

  1. Drop the PDF whose properties you want to change.
  2. Check the current values. A yellow box lists any field where the document information and XMP disagree.
  3. Edit the title, author, subject, keywords, creator, producer, dates or language.
  4. Click Save metadata and download the PDF.

Frequently asked questions

Are my PDFs uploaded to a server?

No. Toolula processes the document inside your browser tab with pdf-lib and WebAssembly, so the file never leaves your device.

Why does my PDF show a different title in different apps?

Many programs update only one of the two metadata places. Adobe Acrobat prefers the XMP metadata when it is at least as new, while older tools read the document information. Saving here writes the same values to both.

Does editing metadata change the pages?

No. Only the document information, the XMP packet, the document language and the title-bar setting change; text, images, form fields and bookmarks stay exactly as they are.

How do I remove all metadata instead?

Use Remove Metadata, which deletes the document information, the XMP packet and other hidden data in one go. The metadata editor links to it.

Can I set the same title on many PDFs?

Yes. The Batch PDF Processor has a metadata action: fill in only the fields you want to set, and use {name} in the title to insert each file's name.

Is it really free?

Yes. You can use every Toolula PDF tool for free, without an account. The free plan has fair-use limits; Toolula Pro, an optional plan, raises them and adds advanced features.
