dcode.fr is a popular cipher and encoding reference. Payload Playground takes encoding further with 31 formats, auto-detection with confidence scoring, a 286-operation pipeline, and chain auto-solver — all running client-side with zero server processing.

dcode.fr processes your input server-side. Payload Playground runs entirely in your browser — no data is ever transmitted. Critical when working with client engagement data, tokens, or sensitive payloads.
Paste a multi-layer encoded string and the chain auto-solver recursively peels back each layer. Base64 inside hex inside URL encoding — solved automatically with each step shown.
Build complex encoding/decoding chains visually. Share recipes via URL. See intermediate results at every step. dcode.fr handles one operation at a time — the pipeline chains them.
Beyond encoding, get 32 payload generators, WAF bypass mutations, JWT attacks, hash generation, and a CLI tool. dcode.fr is a decoder. Payload Playground is a pentest toolkit.
