How it works
Sign and photograph
Use a dark pen on plain white paper in good light. Hold the phone parallel to the page to avoid shadows.
Upload your image
Drag your signature photo into the tool. JPG, PNG, WebP and BMP files up to 10 MB are supported.
Download the transparent PNG
Insert the PNG in Word, Google Docs, Pages or a PDF editor and resize it. The paper disappears.
Tips for the best result
- 💡 A black or dark blue felt-tip pen gives thicker, cleaner lines than a ballpoint.
- 💡 Avoid shadows across the paper; they can be mistaken for part of the signature.
- 💡 Crop tightly around the signature before uploading for sharper edges.
- 💡 Keep a transparent PNG on file so you can reuse the same signature everywhere.
Frequently asked questions
Will the transparent signature work in Word and PDFs?
Yes. PNG supports transparency, and Word, Google Docs, Pages and most PDF editors keep it when you insert the image.
Is a pasted image signature legally binding?
That depends on your country and the document. Many places accept electronic signatures, but some documents require specific e-signature methods. Check the requirements for your case.
Why does my signature look faint?
Light ink or low contrast can fade after background removal. Re-sign with a darker pen and retake the photo in brighter light.
