Drop a PDF to see its title, author, subject and keywords – change what you want and download the updated file.
Its current title, author, subject and keywords appear in the form at once.
Type the new values; an empty field removes that value.
The pages stay exactly as they were – only the document information changes.

HelpRange links verify the reader's e-mail, watermark every page and can be revoked – and show you who opened the document and which pages they read.
Every PDF carries a few lines of document information. The title is shown in browser tabs and search results, the author and keywords are used by document systems and search. Set them correctly before you publish a PDF on a website or send it to a client.
The extended XMP copy of the metadata is removed, so every viewer shows your new values.
Google shows the PDF title in search results. Set a clear title and subject before you upload a white paper, price list or brochure. To remove all hidden information instead, use Remove PDF metadata; for comments, attachments and scripts, the PDF cleaner.
A brochure exported from a design tool has the title “Untitled-3” and the designer as the author. Drop it here, type the product name as the title, your company as the author and three keywords, and save. Browser tabs and search results now show the product name.
Browsers, search engines and PDF readers show the document title instead of the file name – "Final_v7_scan.pdf" or "Microsoft Word - Document1" looks careless on a proposal or a web page.
No – only the document information. The pages stay exactly as they are.
Only for a short time: uploads are deleted right after processing, the result after 30 minutes – or at once with “Delete now”.
The creation date is kept; the modification date becomes the moment you save.
