PDF Metadata Editor reads and lets you rewrite the six classic Info-dictionary fields on a PDF — Title, Author, Subject, Keywords, Creator and Producer — plus shows the document's Creation Date and Last Modified date as read-only, all in your browser. It's for correcting a wrong author name, adding keywords so a file is easier to search for later, or clearing out the name of whatever software produced the file, on a single PDF up to 100 MB. Save Metadata stays disabled and reads “No Changes Made” until at least one field actually differs from what was loaded.
This tool only touches those six fields and one related stream, not everything a PDF can carry. Saving rewrites the Info dictionary you edited and then deletes the file's separate XMP metadata stream if it has one, so a viewer that prefers reading XMP doesn't show stale values that contradict the fields you just changed. It doesn't touch attachments, form fields, embedded JavaScript, bookmarks or image-level metadata — for stripping everything a PDF might reveal beyond the Info dictionary, that's a separate, more thorough tool. Also worth knowing: saving always stamps a fresh Last Modified date at the moment you download, even if you only changed one field like Subject.
How it works
1. Drop a PDF here
One file, up to 100 MB. If it's encrypted, loading stops immediately with a message telling you to unlock it first, since an encrypted file loads with zero readable pages.
2. Review what's already there
Creation Date and Last Modified show read-only alongside whatever Title, Author, Subject, Keywords, Creator and Producer the PDF currently carries.
3. Edit the fields you want to change
A changed field turns blue with a “modified” label next to it. Keywords is a single comma-separated text box — typing “report, 2026, draft” becomes three separate keyword entries.
4. Save Metadata, then download
Once at least one field has changed, Save Metadata becomes clickable. After it reports success, press Download Updated PDF; the filename keeps your original name with “-metadata” added before .pdf.
When you'd use it
Fixing a wrong author name before sharing
A document inherited from a template or a colleague's file often still carries someone else's name in the Author field — correcting it before you send the PDF onward takes one edit here.
Making a scanned or exported PDF easier to find later
Adding a Title, Subject and a few Keywords to a plain scan or export means it turns up more reliably in a file search or a document management system that reads those fields.
Clearing the Producer field before sending a PDF externally
The Producer field usually names the exact software (often with a version number) that generated the file; blanking it before sending a PDF outside your organization stops that detail from going along with it.
Removing metadata copied from a reused template
A resume or letter built by editing an old file can still carry that old file's Title and Author in its properties even though the visible content has completely changed — this fixes that mismatch directly.
The six fields, and what Save actually changes
Title, Author, Subject and Creator are written exactly as typed, including as an empty string if you clear a field. Keywords is split on commas into a list, or cleared entirely if you leave it blank. Producer is handled a little differently: typing a value writes it normally, but leaving Producer blank writes a single space rather than a truly empty string — the tool does this deliberately so the underlying PDF library is forced to overwrite the old value instead of silently leaving it in place. Whatever you change, the Last Modified date is always reset to the moment you save, regardless of which specific field you edited.
Why the XMP stream gets removed
Many PDFs carry a second, separate copy of similar information in an XMP metadata stream alongside the classic Info dictionary this tool edits. If that XMP stream survived unedited, some PDF readers would keep showing its old values instead of the ones you just set. Saving deletes that stream from the document's catalog when it exists, so there's no leftover copy of the pre-edit metadata sitting elsewhere in the file to contradict what you changed.
What this tool doesn't touch
Editing here only affects the Info dictionary fields and the XMP stream — attachments, form fields, embedded JavaScript, bookmarks, and metadata stored inside individual images are all left exactly as they were. If your goal is a full privacy scrub of everything a PDF might be carrying rather than just correcting the document properties, Remove PDF Metadata is built for that broader job.
Frequently asked questions
Can I change the document's Creation Date?
No. Creation Date and Last Modified are shown for reference only — there's no field to edit either one directly.
What happens if I clear the Producer field?
It's written as a single space rather than a completely empty value. This is intentional: it guarantees the underlying PDF library overwrites the old Producer instead of leaving it untouched.
Does editing metadata here remove attachments or my document's editing history?
No. This tool only rewrites the six Info-dictionary fields and deletes the separate XMP metadata stream. Attachments, form fields, embedded scripts and bookmarks are untouched — use Remove PDF Metadata for a more thorough scrub.
Why does the Last Modified date change even though I only edited the Title?
Saving always stamps the current date and time as the new Last Modified value, no matter which of the six fields you actually changed.
Can I remove a field entirely instead of leaving it blank?
Title, Author, Subject and Creator are written as empty strings if you clear them, which removes their displayed value. Producer is the exception — clearing it writes a single space instead of a true empty value.
Will Save Metadata do anything if I haven't changed a field?
No. The button reads “No Changes Made” and stays disabled until at least one of the six fields differs from what was loaded from your PDF.
