PDF ToolsA PDF's title, author and subject do not appear on the printed page, but a reader application, a search index or a file preview can show them. Change PDF Info lets you set these document properties directly.
What you need
- One PDF file, up to 100 MB.
- The details you want it to carry: a title, an author name, a subject, keywords, or a producer and creator.
How to change a PDF's info, step by step
- Open Change PDF Info and choose your file.
The Change PDF Info tool, ready for a file. - Check the pre-filled fields. Whatever title, author, subject, keywords, producer or creator the file already has is filled in for you.
Fields start pre-filled with the details already in the file. - Type the details you want. Leave a field as it is to keep its current value, or clear it to save it empty.
New details typed into every field. - Select "Save these details" and download the result.
The details are saved. Select Download to save the updated file.

What we checked
In testing, every field worked as expected both ways: typing a new title, author, subject, keyword list, producer and creator saved exactly those values, and a field left untouched, such as an author already on the file, kept its original value rather than being cleared or overwritten. Clearing the title field and saving produced a file with no title at all, confirming that a blank field really does mean blank, not "leave unchanged."
Why set a PDF's info
- Give a document a clear title. Many PDF readers show the title, not the file name, in the window or tab.
- Credit the right author. Useful when a document was drafted by one person but should be attributed to a company or team name instead.
- Add keywords for search. Some document management systems index the keywords field.
Tips
- Want to clear everything instead? Use Remove PDF Metadata to strip every document property in one step.
- Combine with bookmarks. A clear title plus bookmarks makes a long document much easier to navigate in a PDF reader.
- Separate keywords with commas. Each one becomes a distinct keyword in the saved file.
