## What is Signature Background Remover?

Lift your signature off the paper and turn it into a clean, truly transparent PNG. Use it in contracts, forms, presentations, and everyday documents, or keep a reusable image of your own handwriting.

Import from Photos or Files, inspect the complete result, and refine it before you export:

- Remove white paper, shadows, and background noise
- Detect page edges, rotate, and correct four-corner perspective
- Crop and refine the signature region
- Adjust background removal and ink appearance
- Repair details with erase, restore, undo, and redo
- Keep the original color or switch to black or blue ink
- Preview on a transparency grid, white, or black background
- Zoom in to inspect strokes and transparent edges
- Export at original or document size
- Save to Photos or Files, copy the PNG, or use the system Share Sheet

Privacy first: extraction and editing happen on your device. The app does not upload your signature or source image. A destination you choose may sync the exported PNG according to its own settings.

Your first signature result is free to export and can be saved, copied, or shared again. After that, make a one-time purchase to unlock the current signature on this device, or choose restorable Lifetime Access for every signature. A current-signature unlock cannot be moved to another device with Restore Purchases. There is no subscription or automatic renewal. Prices shown on the purchase screen come from the App Store.

Only process signatures that belong to you or that you are authorized to use.
