Encoder & Decoder
Base64, URL encode/decode, UUID generation, and Unix ↔ ISO timestamp conversion — all in one tool.
A bundled toolkit covering the four most common everyday dev encodings: Base64 strings, URL-safe encoding, UUID v4 generation, and timestamp conversion between Unix epoch and ISO 8601.
FAQ
Which Base64 variant do you use?
Standard Base64 per RFC 4648 via the browser's native btoa/atob. We handle UTF-8 strings correctly by encoding to bytes first.
Are UUIDs cryptographically random?
Yes. We use crypto.randomUUID() which is backed by a cryptographically secure random number generator in all modern browsers.
