Description by LEAN ASIA CO., LTD Written by the developer, not by AppBrain. Click to read.
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
• A wrapped, unpadded, URL-safe Base64 blob from a log file still decodes cleanly — whitespace, CRLF and base64url handled for you
• Paste a JWT and read its pretty-printed header and payload immediately — the signature never touches a server
• One input, four digests: MD5, SHA-1, SHA-256 and SHA-512 update as you type, with one button to copy all four
• URL-encode a query value and the &, =, + and # characters that break query strings are actually escaped
• Turn any file into Base64 or a ready-to-embed data URI with the correct MIME type — and turn Base64 back into a file
• The String Inspector shows characters, UTF-8 / UTF-16 / UTF-32 byte counts, words and lines the moment text is entered
PERFECT FOR
• Backend and mobile developers debugging an API payload away from the laptop
• QA engineers inspecting auth tokens without pasting credentials into a website
• Sysadmins decoding config blobs and verifying checksums from a phone session
• 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 — 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.
