How to Edit a PDF's Title, Author, Keywords Online

Generated PDFs come with junk metadata — 'Microsoft Word - Untitled1.docx' as title, the IT account as author, blank keywords. Fixing this is the difference between a search-friendly publication and a forgotten file on a shared drive.

When you actually need Edit Metadata

Whitepapers that need searchable titles, internal documentation that needs author attribution, archival files that need keyword tags, publications that need creator credit before going to a CMS.

How to edit metadata, step by step

Open the tool

Go to convertpdfgo.com/metadata. No account, no email, no installation.

Drop the PDF in

Drag the file onto the upload area or click to pick. Files up to 30 MB go through without a queue. Encrypted in transit (TLS 1.3), encrypted at rest, deleted within one hour.

Configure your run

Fill the title, author, subject, keywords you want to change. Empty fields are kept as-is.

Download

The output is a clean PDF — open in any reader.

Common problems and how to avoid them

Edit metadata didn't update the title in my reader

Most readers cache. Close and reopen the file. Some readers show file system name instead of metadata title — that's expected behavior, not a bug.

Keywords are comma-separated but tool wants array

Type comma-separated; we split on commas server-side. Whitespace around commas is trimmed.

Wanted to remove metadata, not change it

Leave the field blank in the form — submit removes the value rather than keeping the original.

A short word on privacy

Three things to know. One: files go over TLS 1.3. Two: files are encrypted at rest while we process them, then deleted automatically within one hour. Three: we don't look at your files or train on them.

Frequently asked questions

Why does PDF metadata matter?

Search engines index it. Content management systems sort by it. Librarians catalogue it. Junk metadata = junk results.

Can I remove metadata entirely for privacy?

Yes — leave fields blank and submit. The output PDF will have empty metadata for those fields.

Are my files private?

Files are encrypted in transit (TLS 1.3) and at rest, then auto-deleted within one hour.

Will it work on protected PDFs?

Not directly — unlock the PDF first with our Unlock PDF tool if you know the password.

Is there a usage limit?

No. Free, no daily cap, no sign-up wall, no watermark.

How long does it take?

About 1-3 seconds for most files. Larger or image-heavy PDFs can take up to 30 seconds.

What's the file size limit?

30 MB as a guest, 50 MB when signed in.
