Edit PDF metadata
Every PDF carries hidden metadata, title, author, subject, and keywords, that shows up in search results, file properties, and citation tools, but few PDF viewers let you change it. DMI's metadata tool reads the existing fields and lets you edit them directly in your browser, then saves a new copy with the updated details. Because the file never leaves your device, this works even for confidential or unpublished documents. It is useful for cleaning up a document before publishing it, correcting an author name, adding search-friendly keywords, or simply seeing what information a PDF is already carrying before you share it with someone else.
How it works
- Upload the PDF whose metadata you want to view or edit.
- Update the title, author, subject, or keyword fields.
- Click Save to download the PDF with updated metadata.
Frequently asked questions
Is editing PDF metadata free?
Yes, DMI's metadata tool is completely free, with no signup and no limit on how many documents you edit. All fields, title, author, subject, and keywords, are editable without any paid plan or watermark added to the file.
Are my files private and safe?
Yes. Metadata is read and edited entirely in your browser, so the PDF is never uploaded to a server. We log usage metadata, including your IP address, tool name, filename, and file size, for up to 12 months to help prevent abuse, never the file content.
Which metadata fields can I edit?
You can view and edit the title, author, subject, and keywords stored in the PDF's document properties. These are the fields most PDF readers, search engines, and citation tools display, so updating them changes how the file is described everywhere it is opened.
