Increase it to remove gray paper texture or a faint shadow.

Increase it to retain smoother antialiased pen edges.
Best for dark or blue ink on light paper. Crop out desks, fingers, stamps, and strong directional shadows first.

Built for real signatures
Paper tone changes. Your ink should not.
The local mask estimates the page color and keeps the strokes that separate from it. These are the three inputs it handles best.
02 · office scan
Dark ink on gray paper
Raise Paper cleanup until the scanner tint disappears without thinning the signature.
03 · ballpoint
Blue ink from a phone photo
Blue-channel separation helps retain brighter ballpoint strokes on a pale page.
Three-step workflow
From phone photo to reusable signature
Crop around the ink
Leave a small paper margin, but remove the desk, hand, page edge, and nearby writing.
Tune the paper mask
Increase Paper cleanup for grain or shadows. Use Stroke edge to keep fine curves smooth.
Check and download
Switch between checker, white, and dark previews. Download only when the halo is gone and every stroke remains visible.
Fine-line rescue
If a stroke disappears, fix the input before forcing the slider
Thin gray pencil marks, glare, severe JPEG blocks, and ink-colored paper can confuse a simple paper mask. A sharper, evenly lit crop usually helps more than aggressive cleanup.
- Photograph the page straight on beside a window, without casting your phone shadow.
- Use the original camera image instead of a screenshot forwarded through chat apps.
- Lower Paper cleanup when loops or light pressure strokes start breaking apart.
- Use a dark preview to expose pale paper halos before downloading.
Ready for documents
Transparent PNG means the page underneath stays visible
A JPG always fills transparent areas with a solid color. PNG can keep the empty area around your ink transparent, so the signature can sit naturally above a document line or colored slide.

Practical answers
Signature background remover FAQ
Is this signature background remover free?
Yes. This page processes the image locally in your browser and does not require an account or credits.
Does Artaivo upload or store my signature?
This tool decodes, processes, previews, and exports the signature inside your browser. It does not send the image to an Artaivo processing API.
Which image formats can I use?
You can use JPG, PNG, or WebP images up to 10 MB and 24 megapixels. The downloaded result is a PNG because PNG supports transparency.
Why is part of my signature missing?
Lower Paper cleanup, raise Stroke edge slightly, and check the result on a white and dark background. If the ink is still faint, retake the photo with even light and better focus.
Why does my signature still have a gray halo?
Crop closer to the signature, then raise Paper cleanup gradually. Strong page shadows or a colored desk inside the crop can make the estimated paper color less accurate.
Can I insert the result into Word, Google Docs, or a PDF?
You can place the downloaded transparent PNG into document tools that support images. This page prepares the image only; it does not sign, edit, or authenticate a document.
