What this tool does
Reads and edits the document properties stored inside a PDF: title, author, subject, keywords and creator.
When to use Edit PDF Metadata
- • Before sending externally. Metadata often records the original author, the software used, and sometimes a file path revealing an internal folder structure.
- • Professional presentation. A document whose title property reads "Untitled-3" looks careless when the recipient opens it, since many readers display the title rather than the filename.
- • Searchability. Document management systems index metadata. Accurate titles and keywords make files findable months later.
- • Correcting exports. Software frequently writes unhelpful defaults — converters and scanners are common offenders.
Why it is useful
- • It improves document professionalism and searchability.
- • It reduces accidental leakage of internal metadata.
- • It helps give files a clear, useful identity before sharing or archiving.
How to use Edit PDF Metadata
- 1. Upload a PDF and review the current metadata values.
- 2. Edit the title, author, subject, keywords or creator fields.
- 3. Save the updated metadata.
- 4. Download the revised PDF with the new document properties.
Privacy and safety note
Current values are read from the file and pre-filled so you can see what is there before changing anything. pdf-lib writes your edits into the document's metadata dictionary. Local to your browser.
