#hex

A fast, fully-local encoding toolkit: encode and decode text between base64, base64url, base32 (RFC 4648), hex, URL percent-encoding, HTML entities, binary and ASCII85 — plus JWT inspection (decode header and payload without verifying the signature). Pure server-side compute, no third-party upstream, so responses are instant and always available. Ideal for developer tools, webhooks, data pipelines, debugging and integrations.
