Frequently asked questions
Which metadata fields can I edit?
The four most common document info fields: title, author, subject and keywords. Each is limited to 200 characters and at least one must be provided.
Does this edit XMP metadata too?
No. This tool edits the classic document Info dictionary only, which is what most viewers display. Extended XMP streams are left as they are and may still contain other fields.
Is metadata the same as the visible text?
No. Metadata is hidden document properties shown in file managers and the reader’s document properties dialog. Editing it never changes the page content.
Do I need to install anything?
No. The PDF is parsed and rewritten in your browser. There is no upload, no account and nothing to install.

Here is what each format is for, and when converting PDF info dictionaries cleaned up is the right move.
What is Clean metadata?
Accurate title and author make files recognizable in libraries and search, while removing personal author strings avoids leaking your identity with shared documents.
When you need it
Edit metadata before publishing or sharing PDFs: give files meaningful titles instead of "document1.pdf", credit the right author, or strip identifying details. It does not touch page content or XMP.
