PDF Metadata

PDF Metadata Editor

AIfreeforever's PDF Metadata editor provides a fast way to inspect and modify the hidden properties stored within any PDF. After you upload a file, the tool immediately extracts all key fields, including the title, author, subject, keywords, creator application, producer library, creation date, and modification date. You can switch between four distinct modes in one workspace: view for a quick summary, edit to update specific fields, remove to strip all metadata for privacy, or export to save details as JSON or text. Since processing happens locally in your browser, your sensitive documents never leave your device.

Online PDF Metadata Viewer with Instant Field Extraction

Checking the hidden information in your PDFs is essential for proper document management and privacy audits. As soon as you load a file, all stored properties appear in an organized list for easy review. Title and author fields clarify the document's origin, while subject and keywords offer descriptors used by many indexing systems for better searchability. You can also see the creator and producer fields to identify which software generated the file, which is often helpful for solving compatibility or formatting problems.

Copy Metadata to Clipboard

One click is all it takes to copy your metadata as structured JSON. You can then paste this information directly into a spreadsheet or database without any manual typing. This feature saves significant time when you need to catalog large batches of files or compare the properties of several documents side by side.

Preview PDF Pages Alongside Metadata

Your PDF pages render in the main center panel while all document details stay accessible in the sidebar. Navigate through the pages to verify content while checking metadata simultaneously. Key stats like the file name, page count, size, and dimensions remain visible at all times, giving you a full overview of the document at a glance.

Edit and Update PDF Document Properties

Updating or adding metadata to your PDF files only takes a few moments. Simply jump to the Edit tab, modify the fields in the sidebar, and save your changes to generate a fresh version of the document. This process only alters the metadata properties, meaning your text, images, and layout remain exactly as they were. The interface includes an unsaved changes indicator so you never lose track of pending updates.

Organize Keywords for Better Document Search

Adding keywords helps make your PDFs much easier to find within cloud storage, desktop search tools, and document management systems. Enter comma-separated terms in the keyword field to tag your file with specific descriptors. Each term is stored as a distinct entry in the PDF spec, ensuring compatibility with professional search tools that scan metadata for indexing.

Maintain Author and Title Accuracy

Files exported from different software often contain generic or incorrect author details. Fixing these fields before you share a report or contract ensures that your recipients see the right information in their file browsers and preview panes. The editor allows you to clean up these identifiers without affecting the rest of the document.

Free PDF Metadata Tool with Complete Privacy

Your PDF documents often contain sensitive personal or financial information that should stay private. Instead of sending files to a remote server, this tool handles everything right in your browser using local processing. Your file loads into memory, is modified locally, and then saves directly to your computer. No data is ever uploaded or stored, and there are no accounts to create or hidden usage limits to worry about.

Remove Metadata for Privacy and Compliance

Metadata can accidentally leak the author's name, the software used, or even internal department details. Before you publish a PDF online or share it with external partners, stripping this hidden info is a smart move for privacy. The Remove tab lets you clear all editable properties at once, giving you a clean file that is ready for public distribution.

Client-Side Processing for Document Security

Since all the heavy lifting happens on your own computer, you can safely inspect and edit confidential contracts, medical records, or tax forms with total confidence that your file contents remain private throughout the entire process. Any PDF you download is generated locally on your own hardware.
