Encode Keyboard
Decode Morse, Binary & Base64
Free · Designed for iPad. Not verified for macOS.
Type, choose a codec, then convert or undo directly from the keyboard. Eight formats run offline on device, with no account or Full Access required.
Encode Keyboard lets you encode and decode text in the app or directly from a custom iOS keyboard.
TYPE, CONVERT, CONTINUE
• Type in a supported text field, choose Encode or Decode, then select a codec
• Tap Convert to replace the current line before the cursor
• Undo the last conversion instantly
• Switch between English and Vietnamese input
EIGHT TEXT CODECS
• Emoji and Kaomoji for expressive messages
• International Morse, UTF-8 Binary, Base64, and ROT13
• Leetspeak and your own Personal Code rules
CREATE AND LEARN IN THE APP
• Convert text with one clear direction-and-codec flow
• Copy, share, or save a result; revisit favorites and recent history
• Learn how all eight codecs work with examples and quick quizzes
• Create, import, and export custom Emoji mappings and Personal Codebooks
PRIVATE BY DESIGN
All transformations run on device. No account or Full Access is required. There are no ads, analytics, or subscriptions. The keyboard has no network access and does not collect what you type.
IMPORTANT
Encoding is not encryption. Do not use these codecs to protect passwords or sensitive information. Binary, Base64, and ROT13 can restore valid input exactly. Morse may normalize accents, case, and spacing. Emoji, Kaomoji, Leetspeak, and Personal Code may be lossy or require the same codebook.
Third-party keyboards are unavailable in secure text fields and some app-specific fields because of iOS restrictions.
