Step-by-step guide
How to add a signature in Word — 4 simple steps
No need to dig through Word settings or install any software. The whole process runs in your browser, on any device.
Upload your Word document
Open Stampsig and drag your DOCX or DOC file into the browser window. You can pick a file from your phone, computer, or tablet. The service also accepts PDF, Excel, and images.
Add your signature
Snap a photo of your signature with your phone or upload an existing scan — the service accepts JPG, PNG, or WEBP. Prefer to draw? Sign directly on the screen with your finger or mouse. The white background is removed from the photo automatically, so your signature looks just like it was signed with a pen.
Tip: for the best result, photograph your signature on a white sheet of paper in good light. If the automatic background removal isn't perfect, drag the brightness slider.
How to remove the background from a signature — automatically
The biggest problem when you paste a photo of a signature into Word is the white rectangle around it. stampsig.com fixes this automatically: you upload the photo and the background disappears in a fraction of a second. The signature sits on the document with no visible edges — just like the real thing.
If the result isn't perfect, there's a built-in brightness slider — nudge it and the background is removed more precisely. It only takes a couple of seconds.
Place the signature on the document
Drag the signature to the right spot on the page. Resize it, rotate it, and move it until it sits exactly where you need it. For a multi-page document, click the All pages button and the signature is copied onto every sheet.
Registered users don't have to upload their signature again — it's saved to your account.
Download the finished document
Click the download button and your signed document is saved as a PDF. The quality of the text and the signature stays intact. The file is ready to send by email or messenger.
Need a stamp too?
Adding a stamp alongside your signature is just as easy: upload a photo or scan of your stamp, let the service remove the background, and place it next to the signature. You can also use ready-made stamp templates for sole traders and companies.
