Elimină fundalul de la semnătură — AI local în browser
Signatures are high-contrast ink strokes, but scans pick up paper texture and shadows. A local browser workflow helps you isolate the stroke while keeping image files off a cloud processing queue.

Why local processing fits signatures
Signed documents are sensitive. Processing locally reduces unnecessary image transfer and keeps the scan on your device for the cutout step.
Practical export tips
Prefer transparent PNG for overlays. If edges look noisy, re-scan with even lighting, then refine feathering in your layout tool after export.
Limits to expect
Very faint pencil lines, smudges, or colored backgrounds can confuse any segmentation model. Start from the cleanest scan you have.
Quick steps
- Open the editor. Open nobg.eu and load your signature scan in the browser.
- Run local segmentation. Let the model estimate foreground; adjust if your UI offers refinement controls.
- Export transparent PNG. Download PNG or WebP with alpha for placement in PDF or email tools.
FAQ
Is my signature image uploaded?
Background removal runs locally in your browser session for this workflow—there is no mandatory upload step to a remote API for the core cutout.
Can I use this for PDF inserts?
Yes. Export a transparent PNG and place it in your PDF editor; verify final print contrast.
Will faint pencil signatures work?
Low-contrast strokes are harder for any model. A darker scan or higher resolution usually helps.
