Key Features

Edit Standard Fields

Update title, author, subject, keywords, creator, producer, creation date, and modification date. The current values are loaded automatically so you only change what you need.

Blank Means Delete

Leave a field empty to remove it from the PDF. You can fix a wrong value or wipe a field entirely without touching the rest.

XMP Sync

If the PDF carries an XMP packet, standard-field edits are written there as well. Readers such as Acrobat and Preview read XMP first, so both copies must agree for an edit to actually show up.

Custom Fields

Edit or remove the custom keys stored in the Info dictionary (anything beyond the eight standard fields), and add your own keys.

Keep Page Content Intact

Only the metadata changes. The visible pages, text, images, and layout are preserved exactly as they were.

Before / After Report

Get a JSON report that compares the metadata before and after editing, so you can verify every change before sharing or publishing.

Private & Local

Editing runs entirely in your browser using pdf-lib. Your PDF never leaves your device and is not uploaded to any server.

Edited PDF + Report

Download the edited PDF alongside the metadata report, or just the PDF if you only need the file.

How to Use

1

Add a PDF

Drag and drop or select the PDF whose metadata you want to change. Works with PDFs created by Word, browsers, scanners, and design tools.

2

Edit the Fields

The tool loads the current metadata. Change any field; leave a field blank to delete it.

3

Review & Download

Inspect the before/after report to confirm your changes, then download the edited PDF and/or the JSON report.

Edit PDF Metadata Example

The metadata is updated, and a before/after report shows the exact changes.

PDF
report.pdf

A PDF whose author and title fields need updating.

Edited PDF + Report
report-edited.pdf, report-edit-report.json

The chosen fields are updated; the report confirms the before and after values.

How to Edit PDF Metadata

Why Edit Metadata

PDF metadata describes the document: title, author, producer, dates, and more. Editing lets you correct wrong values, standardize fields across a set of files, or remove a field entirely — without recreating the PDF.

What You Can Change

The editor works on the eight standard Info fields (title, author, subject, keywords, creator, producer, creation date, modification date) and on custom keys stored in the Info dictionary. Current values load automatically, so you only edit what needs to change; leave a field blank to delete it. Only the fields you actually change are written, and the JSON report lists what was applied, removed, or ignored.

Why the XMP Packet Matters

Many PDFs carry the same values twice: once in the Info dictionary and once in an XMP packet. Readers such as Acrobat and Preview read XMP first, so editing only the Info dictionary can look like nothing happened. When the file has a readable XMP packet, this editor writes both copies — and tells you up front when it cannot.

When to Use This Tool

Use Edit PDF Metadata when you want to:

  • Fix an incorrect author or title before publishing.
  • Standardize document properties across many files.
  • Remove a single outdated field without wiping everything.
  • Update creation or modification dates for archival accuracy.

Limitations

This tool edits the Info dictionary and syncs the eight standard fields into the XMP packet when that packet can be rewritten safely. It does not rewrite unknown XMP packets, remove the XMP packet, delete the Document ID, or touch annotations, links, and embedded files. For removing metadata in bulk — including the XMP packet and Document ID — use the dedicated metadata cleaner.

Frequently Asked Questions

Are my PDFs uploaded?

No. Editing happens locally in your browser using pdf-lib. Your PDF never leaves your device and is not sent to any server.

Which fields can I edit?

You can edit the eight standard Info fields (title, author, subject, keywords, creator, producer, creation date, modification date) and any custom keys stored in the Info dictionary. When the file carries an XMP packet, the standard fields are written to XMP too. The Document ID is never changed here — use the metadata cleaner for that.

I changed the title but my PDF reader still shows the old one. Why?

Most readers (Acrobat, Preview, Windows Explorer) prefer the XMP packet over the Info dictionary. This tool writes both when the file has a readable XMP packet, so reopening the file shows the new value. If a packet exists but cannot be rewritten safely, the tool says so before you run it — in that case remove the packet with the metadata cleaner, or edit the value again afterwards.

How do I delete a field instead of changing it?

Leave the field blank. The tool interprets an empty value as a request to remove that key from the PDF.

Will this change the page content?

No. Only metadata is updated. The visible pages, text, images, and layout remain exactly as they were.

Will editing metadata invalidate digital signatures?

Yes. Rewriting the PDF breaks existing cryptographic signatures, even if the visible pages look unchanged. Do not use this tool on signed documents that must remain valid.

What is the difference between editing and cleaning?

Editing changes the values of specific fields (or deletes them by leaving them blank). Cleaning removes fields in bulk and can also strip the XMP stream and Document ID. Use editing when you want to keep most metadata but fix a few values.
