Codec

Developer Utility

Free

Codec is a fast, offline-first developer toolbox for iPhone and Mac. Every tool runs locally on your device — nothing is uploaded, logged, or sent to a server. Whether you're debugging a JWT, formatting JSON, hashing a file, or just need a clean Base64 conversion, Codec gives you a focused, native tool for the job. What's inside • Base64 — Encode/decode with URL-safe and padding toggles. Auto-detects alphabet and surfaces nested layers. • URL Encode/Decode — Percent-encode query, path, and form components. Handles double-encoded strings. • Hex — Convert text to/from hex with case and 0x prefix options. • Hash & HMAC — MD5, SHA-1, SHA-256, SHA-384, SHA-512, plus HMAC with a user-supplied key. • File Hash — Drag in a file to compute SHA-256 and other digests — no upload required. • JSON Formatter — Pretty-print, minify, and validate. Syntax errors highlight line-precise. • Case Converter — camelCase, snake_case, kebab-case, CONST_CASE, PascalCase, Title Case. • String Inspector — Character, byte, line, and word counts with an entropy estimate. • Regex Tester — Live matching with capture groups, named groups, flags, and per-match highlighting. • JWT Decoder — Decode header and payload, view signature status, watch exp count down live. • cURL Builder — Compose method, headers, and body, export a clean copy-pasteable cURL command. • UUID Generator — Generate v4 UUIDs individually or in bulk. • Password Generator — Cryptographically strong passwords with live entropy readout. • Timestamp — Convert between Unix epoch and human time, with ISO-8601 and custom timezones. • Cron "Next Five" — See the next five fire dates for any cron expression. • Image ↔ Base64 — Drag an image in to get its Base64, or paste Base64 to preview the image. Why Codec • Private by design — 100% on-device computation. No accounts, no analytics, no network calls. • Native and fast — Built for iOS and macOS with platform-native controls. • One app, every tool — No need to juggle websites, browser extensions, or sketchy web converters. • Universal — A single purchase works on iPhone, iPad, and Mac.
