Sign PDF
No more printing a contract just to sign and re-scan it. Draw a signature or upload a stamp image, place it where it belongs, and save. Your file never leaves the browser.

Sign with your mouse or finger
사용 방법
Drag in or click to choose a contract or form. The pages are shown as-is on screen.
Use "Draw signature" to sign with your mouse or finger, or upload a photo of your signature or stamp (JPG/PNG). White backgrounds turn transparent automatically.
Click a saved signature to drop it on the page. Drag to move, use the corner dot to resize. Place it on as many pages and spots as you need.
Hit "Save signed PDF" and a new file downloads. The original text and quality are untouched.
자주 묻는 질문
Is it safe to upload a contract?
Yes — that is the whole point of this tool. The file is never sent to a server; preview, compositing, and saving all happen inside your browser. Open DevTools (F12) → Network while using it and you will see no upload request.
Is this a legally certified e-signature?
This tool overlays a signature image on the document, which is different from certified (PKI-based) electronic signatures. It suits everyday cases where scanned signatures are accepted by both parties — simple contracts, consent forms, replies. For documents that legally require certified e-signatures, use a certification service.
Will the white background of my stamp photo show?
No. For opaque images (JPG, or PNG with a white background) the white background is automatically made transparent, leaving only the ink. Red seals survive because their color is dark enough. PNGs that are already transparent are used as-is.
Does the text quality degrade?
No. The page is not re-rendered — only the signature image is layered onto the original PDF. Text stays text, at original quality.
Does it work with sideways scanned PDFs?
Yes. The page rotation stored in the PDF (90/180/270°) is taken into account, so the signature lands exactly where you see it on screen.
Can I sign multiple pages and spots?
Yes. Flip through the pages and place signatures anywhere. Signatures you create stay in the tray and can be reused — even after switching to a different PDF.
