How to add your scanned signature to a PDF
- Sign a white sheet of paper with a blue or black pen and take a close-up photo in good light, with no shadows.
- Load your PDF and, under Your signature, choose Upload image.
- Leave Remove the white background ticked so only the ink remains.
- Click Add signature, place it and adjust the size.
- Download the signed PDF.
How to take a good photo of your signature
- Plain white paper, no lines or grid.
- A pen or fine marker with dark ink. Blue and black both work well.
- Daylight or a lamp, without your phone's shadow falling on the paper.
- A close, straight photo, with the signature filling most of the frame.
When we remove the white background we keep only the ink and trim the margins. If the photo comes out with a grey background, bring the light closer and take it again.
Private by design
Most online tools upload your files to their servers. Not here: everything is processed in your own browser and nothing is ever sent anywhere. That's why you can safely use it with your ID, passport, payslips, medical reports or contracts.
Is it the same as signing by hand?
It looks very similar, but it's still an image pasted onto the document, in other words a simple electronic signature.
What you create here is a simple electronic signature: an image of your signature placed on the document. Many legal systems accept electronic signatures in general, but they also distinguish stronger types. In the European Union, for example, the eIDAS regulation (article 25) says an electronic signature can't be denied legal effect just because it's electronic, but only a qualified electronic signature, made with a qualified certificate, has by law the same effect as a handwritten one.
In practice, a drawn signature works for many private documents (quotes, school consent forms, timesheets, agreements between individuals) when the other party accepts it. If there were ever a dispute, its value as evidence would depend on other proof, such as the emails you used to send the document. Rules vary by country and by document, and we can't guarantee it's valid in your particular case.
Keep your signature safe
An image of your signature can be copied onto other documents. Don't leave it in shared folders and don't send the signature file on its own: send only the signed PDF. This tool doesn't store your signature anywhere; it's gone when you close the page.

Frequently asked questions
Are my files uploaded to a server?
No. Everything is processed inside your browser. Your files never leave your device.
Is it free?
Yes. No sign-up, no watermark and no usage limits.
Why does my signature have a grey box around it?
The photo's background wasn't white enough. Take another photo with more light or on whiter paper, and leave "Remove the white background" ticked.
What format does my signature need to be in?
A JPG photo from your phone, a PNG or a WebP all work. If you already have a PNG with a transparent background, untick "Remove the white background".
Does it lose quality, and can I still select the text?
No. The signature is added as an image on top of the page and the rest of the PDF stays the same: the text remains selectable and images aren't recompressed.
Do you keep my signature?
No. The image is processed in your browser and disappears when you close the page. It's never uploaded to any server.
