Merge PDF
Merge multiple PDF documents into one unified file while preserving quality and page order.
Update your PDF's Title, Author, Subject, and Keywords quickly and securely. Your file is processed in your browser.
Every PDF file contains "metadata," which is hidden information about the document itself. This includes properties like the **Title, Author, Subject, and Keywords**. Often, this data is incorrect, missing, or automatically generated by the software that created the PDF (e.g., "Untitled" or "Microsoft Word User"). Our Free PDF Metadata Editor allows you to clean up, correct, or add this important information without changing the visible content of your PDF.
Updating your PDF's properties is crucial for several reasons. For professionals and businesses, it ensures that your documents appear polished and correctly attributed when shared. A correct "Author" field gives proper credit, while a clear "Title" and "Subject" make the document easier to find and categorize. For web-hosted PDFs, metadata (especially the Title and Keywords) can be read by search engines, helping to improve your document's visibility and SEO.
Our tool is designed with simplicity and security as the top priorities. When you upload your PDF, it is **not sent to any server**. Instead, the file is processed entirely within your web browser using the powerful `pdf-lib` library. The tool reads the existing metadata and displays it in the form fields, allowing you to make any changes you want. When you click "Save," the tool creates a new PDF with the updated properties right on your device.
Because your file never leaves your computer, this process is 100% secure and private, making it safe to use even for sensitive documents. SmartPDFs provides this utility completely free. You can quickly update your PDF's author, title, or subject, and download the new file instantly, ensuring your documents are professional, organized, and discoverable.
