How to View and Remove PDF Metadata Before Sharing

To check what a PDF says about you, drop it into Docmint's Edit Metadata tool: the title, author, subject, keywords, creator, producer and dates appear immediately. Click "Remove all metadata" to blank every field, or edit the values you want to keep, then click Save Metadata. The page content is not changed.

What metadata does a PDF contain?

Most PDFs carry a small set of document properties alongside the pages:

1. Title, subject and keywords, which describe the document.
2. Author, often filled in automatically from the name on the computer or office account.
3. Creator, the application the document was made in, such as a word processor or design tool.
4. Producer, the library or software that wrote the PDF, often including a version number.
5. Creation and modification dates.

Some files also embed a separate block of XMP metadata with similar information. None of this is visible on the page, which is exactly why it is easy to forget.

Why check metadata before you share a file?

PDFs exported from office software often contain the author's real name and the software version. That may be harmless, but it is not always what you want to publish. A report sent to a client might name a contractor who wrote it, a document from a template might still carry a title like an old project name, and dates can reveal when a document was really drafted.

Software and version details are mostly harmless, but they are information you do not need to give away. Stripping metadata before you publish a PDF on a website, send it to a large mailing list or submit it anonymously is a simple habit that costs a few seconds.

How to view and remove PDF metadata with Docmint

Everything runs in your browser, so the document is never uploaded.

1. Open the Edit Metadata tool and drop in your PDF. The current title, author, subject, keywords, creator, producer and dates are shown immediately.
2. To strip everything, click "Remove all metadata". This blanks every field, including the creation and modification dates.
3. To edit instead, change any field: correct the author, write a clear title, add keywords separated by commas, or set or clear the dates.
4. Click Save Metadata and download the file.

To clean many files at once, drop them together. You can strip them all or apply the same author to each in one pass.

Should you remove the title, or fill it in?

Removing everything is right for anonymous or sensitive files. For documents you publish on purpose, a good title is worth keeping. Search engines and document libraries use the title field, and many PDF viewers and browsers show it in the window or tab instead of the file name.

The title also helps accessibility. Screen readers can announce the document title when the file opens, so a descriptive one such as "2026 Product Price List" is far more useful than a file name like final_v3_export. A sensible approach for public documents: strip personal details, then set the title, set the author to your organization, and add a few keywords.

What does removing metadata not remove?

Metadata removal clears the document properties only. It does not remove annotations or comments, form data, or text hidden under images or behind boxes drawn on the page. If you are trying to hide content, use Flatten PDF, and choose its rasterize mode if you covered sensitive text with shapes, since that turns each page into an image so the text underneath is gone.

It also does not change file names, so rename the file itself if the name gives something away.

Other ways to view PDF properties

Most PDF readers show basic properties: desktop PDF editors usually have a Document Properties dialog, and Preview on a Mac shows them in its inspector. To fix the source, Microsoft Word's Document Inspector can remove personal information before you export. Docmint's Inspect PDF tool gives a fuller report that also covers encryption, permissions, fonts and form fields, which is a good way to double-check a file after you have cleaned it.

Common mistakes to avoid

1. Cleaning metadata and then editing the file again in software that writes its own author and dates back in. Make metadata the last step, or check again afterward.
2. Assuming removing metadata redacts the document. It does not touch page content.
3. Leaving keywords from an earlier version of the document that no longer apply.
4. Forgetting that adding a password later with Protect PDF is a separate step; run it after you have saved the cleaned file.
