Electronic vs cryptographic signatures — the honest difference
This tool places a visible electronic signature: an image of your drawn or typed name, positioned on the signature line. It is legally recognised for everyday agreements in many jurisdictions — but it is not a certificate-backed digital signature, and pretending otherwise helps nobody.
| Property | This tool |
|---|---|
| Draw with mouse/finger | Yes |
| Type a signature | Yes |
| Position & resize freely | Yes |
| Embedded cryptographic certificate | No |
| eIDAS 'qualified signature' | No — needs a certificate authority |
Typical jobs people use this for
- Signing a freelance engagement letter without printing and scanning
- Countersigning a rental inventory checklist on a phone
- Initialling each page of an internal approval document
When this is the wrong tool
Regulated filings that explicitly demand a qualified or certificate-backed signature need a certificate authority service — a drawn signature will be rejected regardless of how it was produced. When in doubt, ask the receiving party which kind they require.
