Electronic Seal vs. Electronic Signature: What's the Difference?
"Electronic seal", "electronic signature", and "digital signature" are used interchangeably in everyday conversation, but they mean different things — and the difference matters when a document needs to hold up legally.
The three terms, untangled
Electronic seal — a digital representation of a traditional seal or stamp. In its simplest form this is just an image. In a compliant system, it is an image bound to a cryptographic credential that identifies the organization and detects tampering.
Electronic signature — a broad legal concept: any electronic data attached to a document that indicates the signer's intent to agree. This can range from a typed name to a drawn signature to a cryptographically secured one. Most jurisdictions recognize electronic signatures by law.
Digital signature — the strongest, most specific form: a signature created with public-key cryptography (usually via a certificate authority). It mathematically ties the document to the signer and proves the content hasn't changed since signing.
In short: every digital signature is an electronic signature, but not every electronic signature is a digital signature. An electronic seal can be backed by a digital signature — or it can be just a picture.
Why a seal image is not a legal signature
This is the most important point on this page. A seal you generate as a PNG or SVG is a visual graphic. On its own it carries:
- no verified identity of who applied it,
- no cryptographic protection against tampering,
- no audit trail of when or by whom it was used.
Pasting a seal image into a document makes it look stamped. It does not make the document legally signed. Anyone with the image file can reuse it, and nothing about the file proves who created the document or that it hasn't been altered.
When you need a compliant signing system
If a document carries legal or financial weight — contracts, filings, official approvals — you need a dedicated electronic signature or e-seal platform that provides verified identity, tamper detection, and an audit trail. The specific requirements vary by region; we cover them in our regional guides:

Where this tool fits
The seal generator creates seal graphics for design mockups, presentations, demos, learning, and lawful personal use. It is intentionally not a signing system — it has no identity verification and produces ordinary image files. Use it to design and visualize a seal; use a compliant platform when a document needs legal effect.
