Static vs dynamic identifiers — picking the right type
When to use a one-shot static identifier and when to use a dynamic one. Trade-offs, plain and clear.
Generating a identifier sounds like it should require an app — and historically it did. Hash Generator runs the same thing in your browser tab, with one tap and no signup.

Static vs dynamic identifiers
A static identifier encodes its content directly. Once generated, it never changes. Pros: works forever, no infrastructure. Cons: can't be updated without re-printing.
A dynamic identifier encodes a redirect URL to a server you control. The destination can be changed without reissuing the identifier. Pros: flexible, analytics. Cons: requires a server, depends on its uptime.
How to choose
- One-shot, never changes: static identifier. Use Hash Generator, you're done.
- Will the destination change? Dynamic identifier. Hash Generator generates the encoding; the redirect logic lives elsewhere.
- Need analytics? Dynamic. Static identifiers are invisible after they leave your device.

Frequently asked questions

What format does Hash Generator output?
Hash Generator offers PNG (for print), SVG (for web), and plain text (for embedding) where applicable.
Will my identifier work after Hash Generator shuts down?
