Add Watermark to PDF Online

To add a signature to a PDF free online, upload your document to Transfonic's PDF Add Signature tool, create your signature by drawing, typing, or uploading an image, place it on the correct page, and download the signed file. No signup, no watermark, no software required — done in under a minute.

You have a PDF that needs an image — a logo on a contract, a photo in a form, a diagram in a report, a signature scan on an application. The document is otherwise complete. All you need is to drop one image onto the right page and save it.

You are reading a PDF — a research paper, a contract, a study guide, a report — and you need to mark the important parts. Highlighting is the fastest way to do it. But unlike a Word document, PDFs are not designed for easy editing, and most tools that let you highlight them either require expensive software, a desktop installation, or a mandatory account signup.

Adding page numbers to a PDF is straightforward — upload your PDF to a free online tool, choose your position and format, and download the numbered file in seconds. No software installation or account is required.
