Convert hex bytes to Base64
Hex is the lingua franca of binary debugging — every hex dump, signature, hash, and certificate fingerprint speaks it. Base64 is the lingua franca of payloads — JSON fields, JWT bodies, signed URLs, email attachments. This converter bridges the two, with tolerant input parsing so you can paste output from xxd, od, a hex editor, or your debugger without massaging it first.
Need the reverse direction? Use Base64 to Hex for the round trip.
