JSON, JWT & Dev Tools: Declip

Paste a JWT, JSON or a Unix timestamp — Declip recognizes it and decodes it instantly. Eight dev tools, fully offline. Nothing leaves your device.

Your clipboard, decoded.

You're away from your laptop and a JWT shows up in an alert log. A JSON blob lands in Slack. A config diff needs checking. The usual answer is some website full of ads — which means pasting a production token into a stranger's server.

Declip does all of it on your device. No account. No sign-in.

PASTE & DETECT One tap. Declip reads the clipboard, works out what it's looking at — JSON, JWT, timestamp, Base64, color, URL — and opens the right tool with the result already on screen. No menu diving, no picking the format yourself.

EIGHT TOOLS • JSON — pretty-print, minify and validate, with the exact offset of a parse error • JWT — decode header and payload, see exp / iat / nbf and whether the token is already expired • Base64 & URL — encode or decode, direction detected automatically, base64url supported • Unix timestamp — epoch to date and back, seconds and milliseconds detected, full timezone list • UUID — generate v4 or v7, up to 100 at once • Hash — MD5, SHA-1, SHA-256 and SHA-512 in a single pass • Color — HEX, RGB and HSL, with ready-to-paste Flutter, SwiftUI and Compose code • Text diff — line-by-line comparison of two versions

WORKS WHERE YOU WORK • Share extension — select text in any app, hit Share, pick Declip. It parses right inside the sheet; no app switch needed.

PRIVATE, ACTUALLY Every tool runs entirely on device. Tool input and output never leave your phone — there is no server to send them to. The clipboard is only ever read when you tap to read it, never in the background. No advertising identifier, no tracking prompt, no account linkage.
