How to Edit a Scanned PDF

May 25, 2026 · By PDFWinner Team

Scanned PDFs are images, but you can still annotate them — add text, white-out, highlights and a signature.

Below we cover exactly how to do it — free, in seconds, and entirely in your browser. Because everything runs on your own device, it works the same on Windows, Mac, Linux, Android and iPhone, with nothing to install and no account to create.

Why editing a scanned pdf matters

Getting this right saves time and avoids the usual headaches — files that are too big to send, broken formatting, or documents that look different on someone else’s screen. With Edit PDF the process is quick and repeatable, and your documents stay private because they are never uploaded to a server.

Annotate the image

Place new text and marks on top of the scanned page.

Make it editable

For full text editing, run OCR and convert to Word.
