Edit Metadata

Every PDF carries a hidden layer of information: a title, an author name, a subject line and a set of keywords. Search tools, file managers and document libraries read these fields before they read anything else. When the metadata is wrong — a report titled "Untitled" or authored by "user123" — the file looks careless and becomes harder to find. This tool lets you edit PDF metadata directly in your browser.

Open the file, and the current title, author, subject and keywords appear in plain text boxes. Change what you need, leave the rest, and download a clean copy. Many PDFs inherit metadata from whoever created the template years ago, so a client proposal might still list a former employee as its author. Fixing that takes about thirty seconds here, with no software to install.

Everything runs locally in your browser. The PDF never leaves your computer, which matters when you are cleaning up contracts, medical records or anything confidential. The tool is free, asks for no signup, adds no watermarks, and there is no limit on how many files you process.

How to edit PDF metadata online

1. Click the upload area or drag your PDF into it — the file opens locally, nothing is sent to a server.
2. Review the existing metadata that loads automatically: title, author, subject and keywords.
3. Type a new title. This is the text most search tools and readers display, so make it descriptive.
4. Update the author field, and adjust the subject and keywords if you want the file easier to find later.
5. Clear any field you would rather leave blank — an empty field is better than a wrong one.
6. Click to apply the changes and download your updated PDF.

When to use this tool

• Fix a report that displays "Microsoft Word - draft_v3_FINAL.docx" as its title in every PDF reader.
• Replace a departed colleague's name in the author field before sending a proposal to a client.
• Add keywords to hundreds of archived invoices so your document management system can actually surface them in search.
• Set a proper PDF title and author on an ebook or whitepaper before publishing it, since some search engines show the metadata title in results.
• Strip the subject and keyword fields from a PDF before sharing it externally, removing internal project codenames.
• Standardize title and author across a batch of scanned documents that all came out of the scanner as "Scan0001".

Tips for the best results

• The metadata title is not the same as the filename — some PDF readers display the metadata title in the window bar, so set both.
• Separate keywords with commas; short, specific phrases work better than long sentences.
• Blank the author field on documents you publish anonymously, since PDF authoring software often fills it in silently.
• For files you plan to publish online, write the title the way you would write a page heading — it can influence how the document appears in search results.
• Keep a consistent author format across your organization, such as "Marketing Team, Acme Ltd", so files sort predictably.
