To edit PDF metadata online for free, open the file in the PDF Metadata Editor, read the title, author, subject, keywords, creator and producer fields it already carries, edit any field you want to change, and click Save metadata to download an updated copy — or use Strip all metadata to clear every field, including any embedded XMP metadata block, in one click. Metadata lives in the PDF's information dictionary, separate from the pages, so editing it changes what readers and search engines display without touching the document itself. Everything runs in your browser, so the file never leaves your device.
Why Metadata Deserves a Look Before You Share
Most readers never open a document's properties panel, yet they see its metadata every day. The title stored inside a PDF is what PDF readers show in the tab, what document systems show in a file list, and what search engines usually display before the file name. When a proposal exported from a word processor still carries the title Untitled document, that is the name the client sees, however careful the file name on the outside may be. Fixing the stored title is a thirty-second job that changes how professional the document looks wherever it travels.
Metadata also leaks. A file exported in a hurry can carry a previous author's name, an internal project code in the subject field, or the name of the software that created it. None of that is visible on the pages, which is exactly why it survives unnoticed through reviews and forwards. Before a document goes outside your organisation, a metadata check is the same kind of hygiene as checking the file name: quick, invisible when done right, and embarrassing when skipped.
The reverse job matters too. Stripping metadata gives you a clean file for anonymous sharing, for publication, or for any case where the document should speak for itself without carrying its production history along. Stripping empties all six standard fields and removes the XMP metadata stream when one is present. It cannot remove names written inside the page content itself, and the file name on the outside is outside the PDF, so those still need their own checks — but the hidden fields are dealt with in one click.
Using the PDF Metadata Editor Tool, Step by Step
- Choose the PDF and read what it already carries. Drop or choose the file. The fields fill in with whatever metadata the file already holds, along with its creation and modification dates, so you can see exactly what needs changing before you touch anything.
- Edit the fields that matter. The title is what readers and search engines display, the author names the document's creator, the subject summarises it, and keywords are a comma-separated list. Creator and producer record the software that made the file; leave them unless you have a reason to change them.
- Save and download the updated copy. Click Save metadata and download. Saving stamps a fresh modification date on the file, which is the honest behaviour for a metadata edit, and the page content is copied without re-rendering, so the reading experience is unchanged.
- Or strip everything for a clean file. Use Strip all metadata to clear every field, including any embedded XMP block, in one click. Reopen the download in the tool to confirm the fields are empty before you share it.
Tip: Do not try to rewrite history through the creation date. The editor shows the creation and modification dates but does not let you falsify the creation date: saving updates only the modification date. If a document's age matters, say so in the document itself rather than editing dates.
Edit, Strip, or Leave Alone: Which Metadata Job Is Which
Not every document needs the same treatment. The table matches the situation to the action.
| Your situation | Action | What changes | Watch out for |
|---|---|---|---|
| Wrong title in reader tabs | Edit the title field | Displayed title corrected everywhere | File name is separate; rename it too |
| Proposal needs author and subject | Edit author, subject, keywords | Document systems show the right names | Keep keywords comma-separated |
| Sharing outside the organisation | Strip all metadata | Six fields plus XMP cleared | Names in page content remain |
| Publishing a clean public file | Strip all metadata | No production history travels along | Check the file name as well |
| Everything already correct | Leave alone | Nothing changes | Do not resave needlessly |
Worked Example: A Proposal That Arrived as Untitled Document
A consultant sends a proposal exported as a file whose stored title is still Untitled document, even though the file name looks finished. Thirty seconds in the editor gives it the proper title, her name as author and the client as subject — and from then on, the client's PDF reader and their document system both show the right name. The worked figures below track the six fields she reviews: title, author, subject, keywords, creator and producer. Of the six, three needed changing, two were already correct, and one — the producer — was left exactly as it was, because the software that made the file is a fact, not a branding choice. The chart shows the field count: six fields reviewed, three edited, two confirmed correct, and one left untouched, adding up to a complete pass over the document's hidden data.
| Metadata field | Before | After | Action |
|---|---|---|---|
| Title | Untitled document | Proposal: Website Redesign for Client | Edited |
| Author | Blank | Consultant name | Edited |
| Subject | Blank | Client project name | Edited |
| Keywords | Blank | redesign, quotation | Confirmed |
| Creator | Word processor | Unchanged | Confirmed |
| Producer | Export engine | Unchanged | Left alone |

Getting the Best Result
Write the title as a reader would search for it, not as a file name. A title such as Website Redesign Proposal — Client Name, March 2026 reads clearly in a tab, a search result and a document list, while a title copied from a file name carries underscores, version numbers and extensions that nobody needs to see. Keep it short, plain and specific, and match it to the document's actual subject rather than its internal project code.
Use keywords sparingly and honestly. A comma-separated list of two or three terms that genuinely describe the document helps document systems file it; a long list of hopeful search terms does not help anyone and looks like stuffing to a human reader who opens the properties panel. Keywords should describe what the document is, not what you wish it ranked for.
Build a metadata check into your send routine for external documents. Open the file in the editor, glance at the six fields, fix or strip as needed, and only then attach it. The check takes under a minute once it is a habit, and it catches the Untitled document, the previous author's name and the internal code that otherwise travel silently with every outward file.
Common Mistakes
1. Fixing the file name and forgetting the stored title. Readers and search engines usually display the metadata title before the file name, so a renamed file with an old stored title still shows the old title.
2. Assuming stripping removes names from the pages. Stripping clears the six fields and the XMP block, but names printed in the page content itself remain. Check the visible text separately.
3. Trying to set the creation date. The editor shows the dates but does not rewrite history. Saving updates only the modification date, which is the honest behaviour.
4. Overfilling the keywords field. A long keyword list helps nobody and reads as stuffing. Two or three genuine descriptive terms are enough.
5. Resaving a file that was already correct. Every save stamps a fresh modification date. If the metadata is already right, leave the file alone.
Key takeaway: PDF Metadata Editor shows and edits the six fields a PDF carries about itself — title, author, subject, keywords, creator and producer — and strips them all, including the XMP block, in one click, without re-rendering a single page and without uploading anything.
Frequently Asked Questions
How do I edit PDF metadata online for free?
Open the PDF in the PDF Metadata Editor, edit any of the six fields, and click Save metadata to download an updated copy, or use Strip all metadata to clear every field.
What is PDF metadata?
Data about the document stored inside the file: title, author, subject, keywords, and the creator and producer software that made it, plus creation and modification dates. Readers, search engines and document systems display these fields.
Why does my PDF show the wrong title in search results and tabs?
Readers and search engines usually display the metadata title before the file name. Fix it here and the correct title travels with the file wherever it goes.
Does stripping metadata make a PDF anonymous?
It removes the six standard fields and the XMP block, which is where names and software usually leak. It cannot remove names inside the page content, and file-system details such as the file name itself are outside the PDF.
Can I set the creation date?
The editor shows the dates but does not rewrite history: saving updates only the modification date, which is the honest behaviour for a metadata edit.
Does editing metadata change the document content?
No. Metadata lives in the information dictionary, separate from the pages, and page content is copied without re-rendering, so the document reads exactly as before.
Is my document uploaded?
No. The metadata is read and rewritten in your browser; the file never leaves your device.
