How do I edit PDF metadata for free online?

Drop your PDF, the existing title, author, subject, keywords, creator, and producer fields appear. Edit any field, click Save, the updated PDF downloads. Free for all users on any PDF.

What is PDF metadata?

PDF metadata is a set of property fields embedded inside the file that describe it: title, author, subject, keywords, the application that created it (creator), and the library that produced the final file (producer). PDF viewers and document-management systems display these fields, and search engines index them.

Why would I want to edit PDF metadata?

Three reasons. One, professionalism: a PDF with the title 'Untitled' or the author 'Microsoft Word' looks unfinished. Two, branding: putting your firm name in the author field makes the document attributable. Three, privacy: stripping metadata removes personal info that can leak through unintentionally (your laptop username, the original file path, draft document titles).

Is this tool really free?

Yes. Editing PDF metadata is free for everyone, on any PDF, with no signup. Tools Pro is not required for this tool. We charge for the higher-volume browser-side tools (merge, watermark, redact, OCR) where the work is heavier.

Is my PDF uploaded when I edit metadata?

No. Metadata editing runs in your browser using the pdf-lib library. Your file never leaves your device.

Does the edited PDF have a Nuvenar watermark?

No. This tool does not add a watermark on any tier. The output is identical to the input except for the metadata fields you changed.

Can I remove all metadata at once for privacy?

Yes. Click Strip All Metadata to blank out every field at once before saving. Useful for anonymising whistleblowing documents, FOI release files, and personal documents before sharing publicly.

What about hidden metadata like the original file path or laptop username?

PDF producers (Word, Pages, LibreOffice) embed varying amounts of incidental metadata in their PDF output. The standard fields (title, author, subject, keywords, creator, producer) are the ones every viewer displays and search engine indexes, and those are the fields this tool covers. For a deeper sanitisation that also removes XMP metadata streams and embedded thumbnails, use Adobe Acrobat Pro.

Will editing metadata change the file size?

Negligibly. Metadata fields are a few hundred bytes total. The output is essentially the same size as the input.

Will the edits survive being opened in Adobe, Preview, Chrome?

Yes. The standard PDF info dictionary fields we edit are universally supported. Every PDF viewer reads them the same way.

Can I edit metadata on a password-protected PDF?

No. Unlock it first with our unlock PDF tool, then edit metadata, then re-add the password if needed.

How is this different from doing File, Properties in Adobe Reader?

Free Adobe Reader can view metadata but cannot save changes. Adobe Acrobat Pro can edit metadata but costs £15.17/mo plus VAT. Smallpdf and iLovePDF do not have a dedicated metadata editor. Preview on macOS lets you edit some fields. This tool is the fastest dedicated cross-platform free option.

What is the Producer field and should I change it?

Producer is the name of the library that wrote the final PDF (often pdf-lib, Skia, or Ghostscript). Most users leave it as is. Some people change it for branding reasons (e.g. 'Acme Solicitors PDF Engine'). It has no functional impact.

Does this work on mobile?

Yes. The tool works on iOS Safari, Chrome on Android, and every modern mobile browser.

What is the Nuvenar Edit PDF Metadata tool?

Nuvenar Edit PDF Metadata is a free, browser-side tool that reads and writes the standard metadata fields of a PDF file: title, author, subject, keywords, creator, producer, creation date, and modification date. It uses the open-source pdf-lib library. Your PDF stays on your device. No signup, no upload, no watermark, no Pro gate.

When to use Edit PDF Metadata

Tidy up before sending: change "Untitled" to a real title, change the author from your laptop username to your name or firm.
Brand outputs: set the author field to your company name on every PDF you send out.
Strip metadata for privacy: remove personal info before publishing or releasing documents.
Anonymise FOI responses: remove the author and creator fields that can identify the staff member who prepared the document.
Improve search and SEO: for PDFs hosted on a website, accurate title and keywords help Google index the document better.

How Edit PDF Metadata works

The tool opens your PDF with pdf-lib, reads the existing Info dictionary fields via pdf.getTitle(), pdf.getAuthor(), etc., presents them in editable form fields, and on save writes them back via pdf.setTitle(value) and friends. The output is the same PDF with updated metadata fields. No other content changes.

The seven standard PDF metadata fields

Title: the document title. Shown in PDF viewer tabs and browser bookmarks.
Author: who wrote it. Often a person, sometimes a firm name.
Subject: a one-line description of what the document is about.
Keywords: comma-separated tags. Useful for document-management search.
Creator: the application that originally created the document (e.g. Microsoft Word, Pages, LibreOffice).
Producer: the library that wrote the final PDF file (e.g. pdf-lib, Quartz, Skia).
Creation and modification dates: usually auto-populated but editable.
