常见问题
Everything worth knowing before you edit it.
help
What counts as "metadata" here?
The document's Title, Author, Subject, and Keywords — the fields a PDF reader shows under "Document Properties." Not the visible page content itself.
help
Why would I need to change this?
Common reasons: fixing a wrong or missing author name, adding a proper title so the file doesn't just show its filename in a reader's tab, or adding keywords to make the PDF easier to find later.
help
Will this change the actual content of my PDF?
No. Pages, text, images, forms, and every other part of the document are left exactly as they were — only the Title/Author/Subject/Keywords fields change.

Is my file kept after I use this?
No. Your file is processed only to update its metadata, then deleted from our servers right away. Max file size: 1 GB.
