Step by step
How to edit PDF metadata in four steps
Under two minutes, no account, and nothing to install.
- 01
Load your PDF
Drag it onto the editor above. The file is read into your browser's memory and never uploaded.
- 02
Change the fields
Edit the title, author, subject, keywords, creator, producer and dates. Clear a field to delete it, or add your own custom properties.
- 03
Review your changes
The pending-changes list shows every field you touched, with its old and new value side by side.
- 04
Download the edited PDF
Save a new copy with your metadata applied. The original file on disk is left byte-for-byte untouched.
Common edits
What people usually come here to change.
- Fix the author on a shared document
- Office software stamps whatever account name the machine was set up with. Replace it with your professional name, your organisation, or nothing at all.
- Give a document a real title
- PDF readers show the Title property in the window and tab instead of the filename. Setting it turns invoice-final-v3.pdf into “Invoice 2026-084 — Acme Ltd”.
- Correct creation and modification dates
- Set either date explicitly, or use the Now button to stamp the current time. Clearing a date removes it from the document entirely.
- Add keywords for search
- Comma-separated keywords are indexed by desktop search and document management systems, making files findable when their titles don't match how people search.
- Track internal properties
- Add custom key/value pairs such as Department, CaseNumber, or Version. Existing custom keys in the file are detected and shown automatically.
- Apply the same metadata to several files
- Export one document's metadata as JSON, then import it into the next PDF to reuse the same title, author and keyword set.
Good to know
Three things that trip people up.
An empty field is a deleted field
Clearing an input removes that entry from the document's Info dictionary rather than writing an empty string. That's usually what you want — a property that exists but is blank still tells a reader the field was deliberately emptied.
Producer is often rewritten by other tools
Many PDF applications overwrite the Producer field with their own name whenever they save a file. This editor preserves exactly what you type, including an empty value — but if you later re-save the document elsewhere, that software may stamp itself back in.
Editing fields is not the same as removing everything
A PDF can hold a second copy of its metadata in an XMP packet. Editing the standard fields doesn't rewrite that packet, so if your goal is a clean document rather than a corrected one, useRemove all metadatainstead.
Questions
Editing PDF metadata — questions.
Which metadata fields can I edit?
All nine standard document properties: Title, Author, Subject, Keywords, Creator, Producer, Creation date, Modification date, and Trapped. You can also add, edit, and delete unlimited custom key/value properties, and the tool shows you the file's XMP packet plus computed details like page count, file size, PDF version, and whether the document is encrypted.
How do I delete just one field instead of all of them?
Clear the input and download the PDF. An empty field is removed from the document's Info dictionary rather than saved as an empty string. To wipe everything at once — including the XMP packet — use the “Remove all metadata” button.
Does editing metadata change the document's content?
No. Only the metadata is rewritten. Pages, text, images, fonts, form fields, annotations, and layout are all preserved exactly as they were. The tool also never modifies your original file — it always produces a new copy for you to download.
What is the Trapped field?
Trapped records whether the document has been through trapping, a prepress process that compensates for slight misregistration between colour plates on a printing press. It accepts three values: True (trapping has been applied), False (it hasn't), and Unknown (unspecified). Outside professional print production it can normally be left unset.
Can I copy metadata from one PDF to another?
Yes. Load the first PDF and choose “Export JSON” to save its metadata as a file. Then load the second PDF and choose “Import JSON” to apply those values. This is useful for applying a consistent title, author, and keyword set across a batch of related documents.
Is there a file size limit?
There's no limit imposed by the tool, because nothing is being uploaded. The practical ceiling is your device's available memory — very large PDFs (hundreds of megabytes) take longer to process and use more RAM, but ordinary documents are essentially instant.
