View, edit, or remove PDF metadata (Title, Author, Keywords) without uploading the file to the web.
Every PDF file stores not only the text and images you see on the screen, but also invisible information — metadata. This is the document's "digital passport," which tells who created it, when, in what program, and what it's about. Often, this data is outdated or contains personal information you wouldn't want others to see.
24glo.com offers a simple and free Edit PDF Metadata tool that allows you to view, modify, or completely remove this hidden information directly in your browser. The main advantage of our solution is absolute privacy. Your files are not uploaded to a server; all processing happens right on your device.
What is PDF Metadata and Why Edit It?
Metadata (document properties) is service information embedded inside a PDF. It helps search engines, catalogs, and operating systems understand the content of a file without opening it. However, sometimes this information can play a cruel joke on you.
Key metadata fields you can change:
- Title: This is not the filename (e.g.,
report_final.pdf), but the internal title of the document. This is what web browsers often display in the tab title or what Google shows in search results. If it says "Document Template v1" while you are sending an important report, it looks unprofessional. - Author: The name of the user on the computer where the file was created. It often contains the name of a secretary, a former employee, or a home computer name (e.g., "Admin" or "Home-PC").
- Subject: A brief description of the content.
- Keywords: Search terms, for example: "report, finance, 2025".
- Creator / Producer: The name of the software used to create the PDF (e.g., "Microsoft Word 2016" or "Adobe InDesign").
- Creation & Modification Dates: The time when the document was created and last modified.
3 Reasons to Use Our PDF Metadata Editor
1. Privacy and Personal Data Protection
Imagine using a contract template downloaded from the internet or borrowed from another company. The metadata of this file might retain the name of an author from another firm or the name of their software. Sending such a file to a client puts your reputation at risk. Our tool allows you to clear all traces of previous authors and programs in a single click. You can set yourself or your company as the author.
2. Improved SEO and Professionalism
If you publish PDF files on your website (price lists, manuals, books), search engines (Google, Yandex) read the metadata. Filled-in Title and Keywords fields help your documents rank higher in search results. A polished title like "Service Price List 2025" looks much better than "New Microsoft Word Document (2)".
3. Security (Offline Mode)
Most online services require you to upload your file to their server. This means your confidential contract or financial report physically travels over the internet. No one knows what happens to the file on a third-party server.
24glo.com works differently. We use technologies that allow editing PDFs directly inside your browser (using your processor's power). When you click "Select File," it goes nowhere. You can even disconnect from the internet after loading the page — and the editor will keep working! This is the ideal solution for lawyers, accountants, and anyone who values confidentiality.
How to Change PDF Metadata in 3 Steps
Our interface is simplified to the maximum so that any user can handle the task, even without technical knowledge.
- Upload the file. Drag and drop your PDF document into the upload area or click the button to select it on your computer/phone. The tool instantly reads the current properties and displays them to you in a convenient form.
-
Make changes. You will see fields for: Title, Author, Subject, Keywords, and others.
- Want to remove the author? Simply clear the text in the field.
- Want to add keywords? Type them separated by commas.
- Want to update the modification date to "now"? The service does this automatically upon saving.
- Save and Download. Click the "Save and Download" button. The browser will create a new version of your PDF with the updated metadata and offer to save it to your device. The original file remains untouched — we create a copy.
Frequently Asked Questions (FAQ)
Can I edit metadata on a phone?
Yes, our service is fully responsive. You can change PDF properties on Android (Chrome, Samsung Internet) and iPhone/iPad (Safari). This is convenient if you need to urgently send a document from a taxi or café and don't have a laptop handy.
Are old metadata versions deleted permanently?
Yes. When you save the file, we overwrite the PDF information block. Old data (the old author's name, etc.) completely disappears from this version of the file. However, remember that the visual content (text on pages) remains unchanged — we only change the hidden properties.
Is Cyrillic (Russian language) supported?
Of course. You can enter the author and title in Russian, Ukrainian, English, and any other languages. We use modern encoding standards, so "garbled text" is excluded.
Are there file size limits?
Since processing happens on your device, we do not set strict limits. You can edit even 100-megabyte books if your computer can handle opening them.
