About Sign PDF
Sign PDF lets you add your signature to any PDF without printing it. Draw your signature with your finger or mouse, type your name in a signature style, or upload a picture of your signature. You can also add the date next to it. Signing happens in your browser, so your file stays on your device.
Use it to sign an offer letter, a rent agreement, a school permission form, an invoice or a visa form. It saves you from printing, signing and scanning again. If you only have a photo of your signature on paper, clean it first with the Signature Background Remover.
