Pocket Decoder

Sep 18, 2026

First release. Paste text or share it in, and Pocket Decoder works out the encoding from the bytes, then keeps going until nothing more decodes. Every step shows the byte count it produced, and you can open a stage and copy that one. Base64, base64url, hex, percent encoding, JWT containers, ROT13, ROT47 and JSON. A reading is accepted only when re-encoding reproduces your input; rotations cannot be checked that way and say so. Your text stays on the device. No ads, no analytics, nothing to buy.
