PDF Metadata Editor
Open a PDF to see and edit its document properties: title, author, subject, keywords, creator, producer and the created and modified dates. Clear everything in one click for privacy. The file is edited in your browser and never uploaded.
Dates use your local time zone. Leave a field empty to remove it from the file.

PDF metadata fields at a glance
The values below live in the PDF's document information dictionary, defined in the PDF specification (ISO 32000). Readers show them under File > Properties, and search engines often use the Title as the result heading.
| Field | PDF key | What it is for | Example |
|---|---|---|---|
| Title | /Title | The document's name, shown in readers and search results | Annual Report 2025 |
| Author | /Author | The person or organisation who wrote it | Jamie Rivera |
| Subject | /Subject | A short description of the topic | Financial results and outlook |
| Keywords | /Keywords | Search terms, usually separated by commas | finance, report, 2025 |
| Creator | /Creator | The app the original document was made in | Microsoft Word |
| Producer | /Producer | The software that wrote the PDF | macOS Quartz PDFContext |
| Created | /CreationDate | When the PDF was first made | D:20250301093000Z |
| Modified | /ModDate | When the PDF was last changed | D:20250312141500Z |
How PDF dates are stored
PDF dates are text strings in the form D:YYYYMMDDHHmmSS followed by a time-zone offset. For example D:20250312141500Z means 12 March 2025, 14:15:00 UTC, and D:20250312091500-05'00' is the same moment written in US Eastern time. This editor shows dates in your local time zone and saves them in UTC, which every PDF reader converts back to the viewer's local time.
Metadata and privacy
Metadata often reveals more than people expect: the author field can contain your full name or computer user name, the creator can show which software and version you used, and the dates show when a document was drafted. Before publishing a PDF or sending it to someone outside your organisation, it is good practice to check these fields:
- Author: replace a personal name with a company or team name, or remove it.
- Title: make sure it is not an old working title or file name such as Copy of contract_FINAL_v3.
- Creator and Producer: clear them if you don't want to show which tools you use.
- XMP metadata: remove it too, as it can hold a second copy of all the above plus editing history.
Metadata is separate from the visible content: names inside the text, comments, attachments and form fields are not changed by this tool.
Frequently asked questions
What is PDF metadata?
It is information stored inside the file about the document rather than on its pages: title, author, subject, keywords, the app that created it (Creator), the PDF library that produced it (Producer), and the creation and modification dates. You can see it in a PDF reader under File > Properties.
Why should I change a PDF's title?
Many PDF readers, browsers and search engines show the Title instead of the file name. A clear title such as 'Annual Report 2025' looks more professional than 'Microsoft Word - draft_v7.docx', and helps the document rank in search results.
How do I remove all metadata from a PDF?
Open the PDF, press Clear all metadata and then Save & download PDF. The title, author, subject, keywords, creator, producer and dates are deleted, and the XMP metadata stream is removed as well.
What is XMP metadata?
XMP is a second, XML-based copy of the metadata that some apps such as Adobe Acrobat embed. If it is left in place, some readers keep showing the old values. The editor removes it by default when present, so every reader shows the values you entered.
Does editing metadata change the pages or quality?
No. Only the document information dictionary is updated. Pages, text, images, fonts, links and form fields are copied unchanged, so the quality stays the same.
Can I edit a password-protected PDF?
No. Encrypted PDFs must be unlocked first, because changing them without the password would damage the file. Remove the protection in a PDF app, then edit the metadata here.
Is my PDF uploaded?
No. The PDF is opened and saved with JavaScript in your browser, so it never leaves your device.
