Both options exist in most signature tools for a reason — they suit different situations, and neither is objectively "more real" than the other, despite how that might feel at first.
A drawn signature carries your own natural variation
Drawing with a mouse or finger produces something closer to how your actual signature looks on paper — imperfect, with the small inconsistencies a genuine signature has. For documents where the signature itself is being scrutinized, this can feel more authentic.
A typed signature in a cursive font is faster and more consistent
Typing your name and picking a script-style font produces a clean, identical result every time, which is genuinely useful when you need the exact same signature across many documents without worrying about a shaky drawn version on a small phone screen.
Neither is inherently more "legal"
Legal validity generally comes from the signer's intent and the surrounding process, not from whether the signature was drawn or typed — a typed cursive signature isn't automatically less valid than a drawn one for most everyday documents.
Match the method to the document's formality
A drawn signature often feels more appropriate for a personal or client-facing document, while a consistent typed signature can work well for internal, repetitive paperwork where speed and consistency matter more than individual character.
Whichever you choose, stay consistent
Switching between wildly different signature styles across documents can look inconsistent if anyone ever compares them side by side — pick one approach and stick with it once you've settled on a version you're happy with.
