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. Twelve 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
TWELVE FORMATS, HONEST LABELS
• RFC 4648 Base64, Base64URL, Base32, and Base16/Hex
• RFC 3986 URL Percent and International Morse
• UTF-8 Binary as an educational app profile; ROT13 as a classic convention
• Emoji, Kaomoji, Leetspeak, and your own Personal Code for expression
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 all 12 formats with specification sources, canonical examples, practice, and quick checks
• 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 formats to protect passwords or sensitive information. Byte-based standard formats, Binary, and ROT13 can restore valid text exactly. Morse may normalize accents, case, and spacing. Emoji, Kaomoji, Leetspeak, and Personal Code are approximate or require the same codebook.
Third-party keyboards are unavailable in secure text fields and some app-specific fields because of iOS restrictions.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Encode Keyboard 1.5.1 improves conversion reliability:
• Convert results in the opposite direction with one tap for 8 formats. Morse normalization still applies.
• Copy and Paste preserve spaces and line breaks; whitespace-only results now have a clear notice.
• Fixed current-line keyboard conversion with Windows-style (CRLF) line breaks.
• Added selection guards and safer Undo checks when the text or cursor context changes.
• Clearer English/Vietnamese errors and optional Morse normalization details.
• Convert remains one tap, offline, with no Full Access required.
