Frequently Asked Questions:
How do I take the best photo of my pen signature for background removal?
Write your signature with a dark blue or black gel or ink pen on plain white printer paper. Take the photo in good lighting directly from above without casting a heavy hand shadow over the paper.
Does the background remover leave any white box artifacts over the PDF?
No. The background eraser creates a genuine transparent PNG where all paper pixels are removed, ensuring that any lines, text, or watermarks beneath the signature remain completely visible.
Can I change the ink color of my uploaded signature photo?
Yes! Once uploaded, you can keep the original ink or instantly tint it to official legal dark blue or sharp black to match your company’s document standards.
Is my uploaded paper signature saved or shared with third parties?
No. The image processing is executed entirely within your browser memory. Your private handwritten signature is never uploaded, stored, or analyzed on external servers.
