Encode, decode & hash — fast

A developer toolbox for the everyday conversions: Base64, URL, hexadecimal, HTML entities, MD5 / SHA hashes, and a JWT decoder. Pick an operation, paste your text, get the result. Everything runs locally — nothing you enter is stored.

Get this result as JSON (developer API)

curl "https://encode.wrapper-agency.com/api/v1/encode?op=base64-encode&value=Hello%2C%20world!"

Free encode/decode/hash API — no key during beta. Everything is computed locally; nothing you enter is stored.
