What is a PDF Metadata Editor?
A PDF Metadata Editor is an online tool that allows you to view and modify the hidden document properties embedded inside a PDF file — without changing its visual content or layout. These properties, known as metadata, include information such as the document title, author name, subject description, keywords, and creation or modification dates.
Toolnex AI's PDF Metadata Editor runs entirely in your browser, which means your files are never uploaded to any external server. Everything happens locally and privately on your own device.
Beyond just editing metadata, Toolnex AI's tool also includes a built-in PDF content editor. This means you can click on any text block in the PDF preview and modify it directly — changing the wording, font style, font size, colour, and alignment.
In summary, a PDF Metadata Editor is an essential utility for students, professionals, developers, content creators, and anyone who works regularly with PDF documents. Toolnex AI's free PDF Metadata Editor brings all of this functionality to you instantly — no installation, no registration, no cost.
