How to edit pdf in 3 steps

  1. Add the PDF

    Open the document in the built-in canvas editor.

  2. Annotate the page

    Pick a tool and mark up the page; undo anything you dislike.

  3. Download the edited PDF

    Save a flattened, shareable copy.

Most edits to a PDF are last-minute: a missing signature, a highlight for a colleague, a page number on a contract. PDF Editor handles those on the spot without a desktop install, an account or a subscription. Annotated output is flattened into the page, so the recipient sees exactly what you saw regardless of the reader they use.

No signup

No account, no email, no credit card, no trial to remember.
