How to edit PDF metadata in 4 steps
FreePDFLab runs entirely in your browser, so the steps below happen on your device without anything being uploaded to a server.
Upload the PDF
Drop your file onto the upload area or click to browse. The metadata edit runs locally so the document never leaves your device.
Set the new metadata
Update the title, author, subject, and keywords. Leave a field empty to keep its current value untouched — only the fields you fill in are written.
Process the change
Click "Process". FreePDFLab writes the new metadata into the PDF info dictionary using pdf-lib. The page content is left exactly as it was.
Download the updated PDF
Preview the file and download. The new metadata appears in any PDF reader that shows document properties — Acrobat, Preview, Chrome, Firefox.
Why edit PDF metadata with FreePDFLab
Improve searchability
A descriptive title, author, and keywords help PDF library tools, file managers, and document-management systems index your file correctly.
Clean up incorrect author info
PDFs exported from Word or design tools often carry the original author’s name. A quick metadata edit replaces it with the right person before sharing.
Brand your shared documents
Set the title and subject so the PDF shows up with the right name in a recipient’s file list — not "Untitled" or "Document1".
Private, no server step
Metadata edits happen locally. The PDF never leaves your device, which matters when you are scrubbing author info from a sensitive draft.
Frequently asked questions
What fields can I edit?
Title, author, subject, and keywords. These are the four most-used fields in the PDF info dictionary and the ones most readers display in their document properties view.
Does editing metadata change the document content?
No. The PDF pages — text, images, layout — remain byte-identical to the original. Only the metadata dictionary at the file’s root is rewritten.
Can I remove a metadata field entirely?
You can blank it out by leaving the field empty in the form. The field is then set to an empty string in the output PDF. Removing the field from the dictionary entirely is on the roadmap.
How do I enter multiple keywords?
Separate keywords with commas — for example "finance, q4, report". FreePDFLab stores each as a separate keyword entry in the PDF.
Will my changes show in Adobe Acrobat?
Yes. The PDF info dictionary is the standard place readers look for document properties, so Acrobat, Preview, and most other readers will show your new values.
Is my PDF uploaded when I edit metadata?
No. The edit happens in your browser using pdf-lib. The file stays on your device.
