Sign PDF is a Pro feature ($5/month flat, free trial) — the everyday tools (merge, split, rotate, organize, watermark, page numbers, image to PDF) stay free with no sign-up, no watermark and no daily limit.
Open Sign PDF, drop your file, set the options, and download the result in a few seconds — processed securely, no queue and no ads.
Sign PDF needs our conversion servers, so the file is sent over an encrypted connection, used only for your task and deleted within 24 hours. The page tools (merge, split, rotate, organize, page numbers, watermark, crop, form filling, image to PDF) run entirely in your browser instead and never upload anything.
Draw it with a mouse or finger, type it and pick a style, or upload an image of your real signature — then place it where it belongs on the page and drop in any dates or text the document needs.
No. This places a visible signature on the page, which is what most documents ask for. For a cryptographically verifiable PKI signature, use Certify PDF instead.
