In short: PDF metadata is the document information stored inside the file — title, author, subject, keywords, creator app and dates — which PDF viewers, browsers tabs and search engines display.
About Edit PDF Metadata
Every PDF can carry document properties. The title is what browsers show in the tab and what search engines often use as the result headline for PDFs; the author field may reveal the name of the person or company account that created it. Exported PDFs often have a meaningless title like “Microsoft Word - final_v7.docx” or none at all.
This editor reads the Info dictionary with pdf-lib, lets you change each field and saves a copy. Clear all fields empties every field before saving, which is useful before publishing a document. XMP metadata streams written by some apps are not edited.
How to use Edit PDF Metadata
- Choose a PDF; its current properties appear.
- Edit the fields, or press Clear all fields.
- Press Save PDF to download the updated copy.
Examples
Change the title from “Microsoft Word - brochure.docx” to “2026 Product Brochure — Acme” so search results and browser tabs show a meaningful name.
Clear the author field that shows your personal account name before sending a file outside your company.
Frequently asked questions
Does editing metadata change the content?
No. Only the document information is changed; pages are untouched.
Why does my PDF viewer still show the old title?
Some apps prefer XMP metadata if present. This tool edits the standard Info dictionary, which most viewers and browsers use.
Is metadata the only hidden information?
No. PDFs can also contain comments, form data, attachments and hidden layers. Clearing metadata does not remove those.
Is my PDF uploaded?
No. Everything happens in your browser. You can check this yourself: open your browser’s developer tools, switch to the Network tab and use the tool — no request carries your input.
