Paste a Base64 string, tap once, read the answer โ€” right on your iPhone, fully offline. No web converter, no upload, no wondering who just logged the token you pasted. Base64 Encode Decode Offline is a developer scratchpad built for the real thing you paste: blobs copied out of logs and terminals. The decoder tolerates URL-safe alphabets, missing padding and line-wrapped copy-paste, auto-detects whether you meant encode or decode, and refuses garbage instead of returning silent nonsense. URL decoding is byte-accurate, so a leading BOM or odd byte is preserved instead of being quietly eaten. Everything renders in a proper monospaced font. WHAT YOU GET โ€ข A wrapped, unpadded, URL-safe Base64 blob from a log file still decodes cleanly โ€” whitespace, CRLF and base64url handled for you โ€ข Paste a JWT and read its pretty-printed header and payload immediately โ€” the signature never touches a server โ€ข One input, four digests: MD5, SHA-1, SHA-256 and SHA-512 update as you type, with one button to copy all four โ€ข URL-encode a query value and the &, =, + and # characters that break query strings are actually escaped โ€ข Turn any file into Base64 or a ready-to-embed data URI with the correct MIME type โ€” and turn Base64 back into a file โ€ข The String Inspector shows characters, UTF-8 / UTF-16 / UTF-32 byte counts, words and lines the moment text is entered PERFECT FOR โ€ข Backend and mobile developers debugging an API payload away from the laptop โ€ข QA engineers inspecting auth tokens without pasting credentials into a website โ€ข Sysadmins decoding config blobs and verifying checksums from a phone session โ€ข Students seeing exactly how encodings and hash digests behave WHY NOT JUST USE A WEB CONVERTER? Because every online encode/decode tool receives your string on its server โ€” and the strings developers convert are exactly the ones that should never leave the machine: session tokens, API keys, connection strings, JWTs. This app does all conversion and hashing on the device with Apple's CryptoKit. It works in airplane mode. PRIVATE BY DEFAULT No accounts, no tracking of your content, no network needed to convert. Your inputs and your conversion history are stored only on your iPhone. FULL ACCESS Pro unlocks unlimited saved conversions, file conversion beyond 5 MB in both directions, and Batch mode to convert many lines in one pass. Full access is available as a weekly subscription, a yearly subscription, or a one-time lifetime purchase. Decode that string before the next station โ€” download Base64 Encode Decode Offline.

About

AO

Features
Read full description

AO Mobile is the companion app for Agent Orchestrator, the desktop workspace for agent-driven development. Your agents keep working while you step away from your desk. AO Mobile keeps you in the loop โ€” see what every worker is doing, answer the ones that are blocked, and keep work moving from your phone. REQUIRES THE AO DESKTOP APP AO Mobile is a thin client. It connects directly to Agent Orchestrator running on your own computer, over your local network or your Tailscale network. There is no cloud service and no account to create. Your code, conversations, and repositories never leave your machine. WHAT YOU CAN DO โ€ข Live Kanban โ€” every worker session on one board, grouped by what needs your attention: working, needs you, in review, ready to merge. โ€ข Get notified when an agent stops โ€” a push notification arrives the moment a session needs your input, and tapping it opens that exact conversation. โ€ข Chat with any agent โ€” full conversation history, streaming responses, approvals, model and provider switching, file attachments, and voice input for when typing is impractical. โ€ข Follow pull requests โ€” open and draft PRs with their checks, CI status, and review state. โ€ข Talk to the orchestrator โ€” your project-level planning agent, for thinking through direction and delegating new work. โ€ข Drop into the terminal โ€” attach to a session's live terminal when you need the raw view. โ€ข Preview running work โ€” open a worker's browser preview to see what it built. BUILT FOR TRUST The desktop's connection to your phone is opt-in and off by default. When you enable it, AO opens a separate local listener protected by a rotating password, and pairing happens by scanning a QR code shown on your desktop. Turning it off closes the connection immediately. GETTING STARTED 1. Install Agent Orchestrator on your Mac, Windows, or Linux machine. 2. Turn on Connect Mobile in the desktop app. 3. Scan the pairing QR code with this app. Agent Orchestrator is open source. Learn more at aoagents.dev.
