Stretch to fill: Signature fills the entire frame exactly — no white borders. Width and height match exactly. Best when the portal checks pixel dimensions strictly.
Fit + white background: Preserves the signature's natural proportions. White fills any gaps on sides or top/bottom. Best when you want the signature to look natural.
Fit + transparent (PNG only): Like above but gaps are transparent. Use only if the portal accepts PNG format.
