Edit PDF Metadata
Edit a PDF's title, author, subject, and keywords for better organisation and SEO.
Fix the hidden labels attached to every PDF
Every PDF carries a set of metadata fields — title, author, subject, keywords — that sit under Properties in Acrobat and Info in most readers. These are what Windows Explorer, macOS Finder, Google Drive, and even Google Search read when they index or display your file. When those fields still say “Microsoft Word - untitled.docx” or carry the previous editor's name, the wrong information follows the PDF everywhere it goes.
Reasons to update metadata
- Privacy — strip the original author or template creator from a shared document
- Searchability — fill title and keywords so library systems and cloud drives find the file
- SEO — when you host a PDF on your site, the title field is what Google shows in search results
- Branding — stamp consistent author and subject on every deliverable your team sends out
What each field means
Title — the human-readable name shown in browser tabs and search snippets. Author — person or organisation who produced the file. Subject — a one-line description; treat it like a meta description. Keywords — comma-separated terms that help enterprise search and some PDF tools categorise the document.

Frequently asked questions
Does this change the visible content of the PDF?
No. Metadata lives in the PDF's info dictionary — nothing on the page changes, only the properties shown by readers and file managers.
Will Google use my title field?
Yes. For PDFs indexed by Google, the Title metadata field is typically what appears as the clickable search-result headline, with the first page used as the snippet.
Can I clear all metadata to anonymise the file?
Set each field to blank and save — the PDF will be written with empty metadata. Note: creation/modification timestamps are still stored; run Flatten PDF afterwards for extra cleanup.
Does it edit XMP metadata as well?
The basic info dictionary is updated, which covers the fields every reader shows. Deep XMP blocks used by Adobe products may need a desktop editor.
Is the PDF uploaded?
No — editing happens locally in your browser; the file never leaves your device.
