A contract, a permission slip, an NDA — it lands as a PDF, and the instructions say “print, sign, and scan back.” Most people don’t own a printer anymore, let alone a scanner. Here’s the version that skips both.
That workflow exists because it’s what people know, not because it’s necessary. A printed-then-scanned signature is usually lower quality than one placed digitally — it picks up scanner noise, skew, and shadow, and the rest of the page gets re-compressed along with it. A signature drawn or typed directly onto the PDF stays crisp and keeps the document’s original text sharp, because nothing else on the page is touched.
There are three ways to do it without a printer. Type it, if your name in a clean script or serif style is good enough for the document — type your name and pick a style from a preview grid, and it shows your name, not a placeholder. Draw it, with a mouse or trackpad on a laptop, or a finger on a touchscreen; if you’re at a desktop without a touchscreen, a QR code lets you draw the signature on your phone instead, and it lands in the same spot on your computer automatically, no file transfer needed. Or upload it, if you already have a signature saved as an image — a photo of one on paper, or an export from another app — upload it once and place it on any page.
Open the free Sign PDF tool and drop in your file. Click Sign, choose type, draw, or upload, and drag the result onto the page. Resize it from the corner handles and rotate it if it needs to sit at an angle to match a signature line. Add a Date stamp next to it if the document needs one — it defaults to today’s date and can be edited freely. Download, and the signed PDF saves straight to your device. Nothing here touches a server: the PDF opens locally, the signature is drawn directly into the page, and pressing Download just saves the result. A signature relayed from your phone passes through a short-lived connection that’s discarded the instant your computer receives it.
Three adjacent needs call for a different tool. A repeating mark on every page — “CONFIDENTIAL,” a company seal, “APPROVED” — isn’t what a signature is for, so use Add Stamp to PDF for a single corner mark on every page, or Add Watermark to PDF for something tiled across the whole page. If the document also needs edits — a missing page, a rotated scan, redlines — before it’s ready to sign, our Edit PDF tool covers crop, delete, reorder, rotate, and page numbers in the same pass. And if you want to lock it after signing so it can’t be edited further, Lock PDF adds a password once you’re done.
