A scanned signature looks personal but is hard to reuse cleanly. A typed, generated signature is consistent but needs to avoid looking like a plain font.
A scanned signature is literally your own handwriting, photographed or scanned and cleaned up as an image. It carries a real personal history, but paper scans often pick up shadows, uneven lighting, and a background that needs manual removal before the image looks clean.
A generated signature exports with a transparent background instantly, at a consistent size and color every time. The tradeoff is that a plain typed signature using a stock script font can look identical to thousands of other people's signatures if the tool just maps text to a font.
A stroke-based generator avoids that problem by varying the letterforms per generation, so the result looks closer to genuine handwriting variation instead of a repeated font stamp.
For document drafts, invoices, and email, a clean generated signature is usually faster and more consistent. For situations where the exact original handwriting matters most, a well-scanned and background-removed signature is still the more literal option.
Not inherently. What matters most for everyday documents is that the signature is legible, consistent, and placed correctly. For anything requiring certified legal signing, neither a scan nor a generated image alone provides that certification.
