A PDF's metadata — its title, author, subject, and keywords — is what shows up in a file browser's "Properties" panel, in search results, and in some document management systems. A PDF exported without proper metadata often just shows a generic filename or "Untitled" where a real title should be.
This tool lets you set a PDF's metadata directly — no need for specialized desktop software — and gives you back a file with the same content and page count, just properly labeled.
How it works
Upload your PDF and fill in any of the metadata fields you want to set: title, author, subject, and keywords (comma-separated). The tool rebuilds the PDF with every original page intact and applies the metadata you entered, then gives you the updated file to download.
- Upload a PDF file.
- Fill in any of the title, author, subject, or keywords fields.
- Generate and download the updated PDF.
Examples
Labeling a scanned document
A scanned PDF named "scan0042.pdf" with no metadata can be given a proper title like "2025 Annual Report" and an author name, making it identifiable at a glance in a file browser or document management system.
Adding keywords for searchability
Adding keywords like "invoice, Q3, client-acme" to a PDF makes it easier to find later in tools that index PDF metadata for search.
Who should use it
- Labeling scanned documents with a proper title and author.
- Adding searchable keywords to PDFs stored in a document management system.
- Standardizing metadata across a batch of related documents.
Industry applications
- Office administration and document management
- Legal and compliance document handling
- Publishing and content archiving
Advantages
- Sets title, author, subject and keywords in one step, with no signup or watermark.
- Preserves the original PDF content and page count exactly.
- Works entirely in the browser session — no desktop software required.
Limitations
- Can't open password-protected or corrupted PDFs.
- Doesn't auto-suggest metadata values from the document's content.
- Only sets standard metadata fields, not custom or extended XMP metadata.
Common mistakes to avoid
- Assuming metadata changes the visible content of the PDF, when it only affects document properties.
- Leaving all fields blank and expecting the tool to auto-detect a title from the content.
- Uploading a password-protected PDF, which can't be read by this tool.
Best practices
- Use a clear, descriptive title rather than leaving it as a generic filename-derived value.
- Add keywords that match how you'd actually search for the document later.
- Keep author names consistent across related documents for easier filtering in document management tools.
Tips
- Set metadata right after generating or scanning a document, before it gets filed away and forgotten.
- Use consistent keyword conventions across related documents to make them easier to find later.
