Edit PDF Metadata — Free
Change title, author, subject, keywords, creator, producer, and dates in any PDF. Runs entirely in your browser — no server upload, no account, instant download.
Open PDF Metadata Editor →Every PDF file carries a hidden layer of information called metadata — fields like title, author, subject, and keywords that describe the document without appearing on its pages. When you download a PDF from a colleague, a template service, or an export tool, these fields are often wrong, missing, or filled with software-generated defaults that reveal more than you intend. Editing them requires either Adobe Acrobat Pro (expensive) or the right free online tool.
The NextUtils PDF Metadata Editor lets you view and update all eight standard PDF metadata fields directly in your browser. Your file never leaves your device — the tool processes everything locally using the pdf-lib library — so it is safe for sensitive documents. This guide explains every metadata field, when you would want to change it, and how to use the tool step by step.

What Is PDF Metadata?
PDF metadata is structured data embedded in the file header — separate from the page content — that describes the document. PDF viewers use it to populate the document title in browser tabs and taskbars. Operating systems use it in file explorers and search indexes. Search engines and document management systems use the keywords and subject fields for indexing.
The PDF specification defines eight standard metadata fields. Here is what each one stores:
| Field | What it stores | Example |
|---|---|---|
| Title | The document's name, as it should appear in viewers and search | Q3 Financial Report 2026 |
| Author | The person or organisation who wrote the document | Acme Corp Finance Team |
| Subject | A short description of what the document is about | Quarterly revenue and expense summary |
| Keywords | Comma-separated terms for document search and indexing | finance, Q3, revenue, 2026 |
| Creator | The application that originally authored the document | Microsoft Word |
| Producer | The software that converted or rendered the final PDF | macOS Quartz PDFContext |
| Creation Date | When the document was first created | 2026-01-15T09:32:00 |
| Modification Date | When the document was last modified | 2026-03-28T14:15:00 |
Tip: To see a PDF's current metadata in any PDF viewer, open the file and look under File → Properties (Adobe Acrobat), or Cmd/Ctrl+D in most viewers. The NextUtils tool shows all fields automatically when you upload.
Why Would You Edit PDF Metadata?
There are more reasons to edit PDF metadata than most people realise. The most common scenarios:
Fix wrong or placeholder values
When you export a PDF from Word, Google Docs, or InDesign, the title field often defaults to the file name, the author to your Windows account name, and the creator to a version string of the export software. If you are sharing the document professionally, these defaults look careless or expose internal information (a personal username, a draft file name, which software version you use).
Remove personal information for privacy
The author field frequently contains a full personal name pulled from the OS user account. The creator and producer fields reveal which software — and sometimes which version — produced the file. Before sharing a PDF publicly or with an unknown recipient, clearing these fields removes personally identifying information that was embedded without any obvious indicator.
Improve document search and indexing
Document management systems, SharePoint, Confluence, and corporate intranets index PDF metadata for full-text search. Adding a meaningful title, a descriptive subject, and relevant keywords makes documents findable by colleagues without needing to open every file. This matters most for PDFs stored in shared drives or internal knowledge bases.
Rebrand or update inherited documents
When a company rebrands, changes ownership, or takes over a document from another team, the existing metadata may reference the old organisation name, an ex-employee, or an obsolete project title. Editing the metadata updates the document's identity without altering the page content or requiring a full redesign.
Note: PDF metadata editing changes only the metadata fields — not the page content, fonts, images, or layout. If a PDF has digital signatures or security restrictions that prevent modification, some editors will fail. The NextUtils tool processes standard (unrestricted) PDFs up to 25 MB.
How to Edit PDF Metadata — Step by Step
The tool works entirely in your browser. No file is uploaded to a server at any point — everything runs locally via the pdf-lib JavaScript library.
Step 1: Upload your PDF
Open the PDF Metadata Editor and drag your file onto the upload area, or click to open the file picker. The tool accepts PDFs up to 25 MB. You do not need to sign in or create an account.
Step 2: Review the current metadata
Once your PDF loads, the tool reads and displays the current values for all eight fields side by side with editable input boxes. You can see exactly what the file currently stores before changing anything — useful for auditing what information is already there.
Step 3: Edit the fields you want to change
Click into any input and type the new value. You can update just one field or all eight in a single pass. To clear a field entirely, delete its content and leave it blank — the tool will write an empty string for that field in the output PDF. The tool uses keyboard shortcuts: Ctrl+S saves, Ctrl+R resets to the original values, and Ctrl+P toggles a metadata preview.
Step 4: Save and download
Click Save Changes. The tool rewrites the PDF with your updated metadata and immediately triggers a download. The output file is identical to the original in every other respect — same pages, same text, same images, same file size minus the changed metadata. Processing typically takes under a second for most PDFs.
What PDF Metadata Can Reveal About You
Many people share PDFs without realising what the metadata reveals. Here are the most common sources of unintended disclosure:
The Author field exposes personal names
Word and Google Docs both populate the Author field from the OS account name or Google account name of whoever created the document. If you exported a template from your personal account and are sharing it professionally, your full name (or username) is embedded in the metadata of every copy.
Creator and Producer reveal your software stack
The Creator and Producer fields record the exact application and version used to make the PDF. Anyone who opens the file properties can see whether you use Word 2019, InDesign CC 2024, Ghostscript 10.0, or LibreOffice Writer. For some use cases — legal documents, competitive tenders, anonymous submissions — this information should not be visible to recipients.
Dates can contradict your timeline
The Creation Date records when the document was first created, and the Modification Date records the last save. If you are presenting a document as having been prepared recently but the creation date says two years ago — or vice versa — those timestamps create an inconsistency that recipients can notice.
Tip: For maximum privacy before sharing, clear the Author, Creator, and Producer fields, and set the dates to the current date. This strips the most commonly inspected personal identifiers from the metadata without altering any page content.
Frequently Asked Questions
What is PDF metadata?
PDF metadata is information stored in the file header that describes the document — including title, author, subject, keywords, the software that created it, and timestamps. It is not visible on any page but is readable by PDF viewers, file explorers, and search engines.
Can I edit PDF metadata without Adobe Acrobat?
Yes. The NextUtils PDF Metadata Editor handles all eight standard fields in your browser — no Acrobat license or desktop software required. It processes the file locally using the pdf-lib library, so your document never leaves your device.
Does editing metadata change the PDF content?
No. Metadata is stored separately from the page content in the file structure. Editing the title, author, or any other metadata field has zero effect on the text, images, fonts, or formatting of the pages inside the document.
Is it safe to edit PDF metadata using an online tool?
With the NextUtils tool, yes. The PDF is processed entirely in your browser — nothing is transmitted to a server. The file data exists only in your browser's memory during editing and is discarded when you close the tab. This makes it suitable for confidential or sensitive documents.
What is the difference between Creator and Producer?
Creator is the application that originally wrote the document (e.g., Microsoft Word, InDesign). Producer is the software that generated the final PDF output (e.g., Adobe PDF printer, macOS Quartz, Ghostscript). When you write in Word and export using the built-in Save as PDF, Word is both Creator and Producer. When you print a web page to PDF via the OS, the browser is the Creator and the OS print driver is the Producer.
How do I remove all metadata from a PDF?
Upload the PDF to the NextUtils editor, clear all eight fields — title, author, subject, keywords, creator, producer, and both dates — and click Save Changes. The downloaded file will have blank standard metadata fields. Note that some PDFs also contain XMP metadata streams in addition to the standard fields; the tool targets the standard InfoDict fields.
