Escape and unescape strings instantly for 10 language modes: JSON, JavaScript/TypeScript, Python, Java, C#, SQL, HTML, XML, CSV, and Regex. Paste raw text, pick a mode, and hit Escape — or paste escaped text and hit Unescape to recover the original. No data leaves your browser. Select Language / Context Bulk mode (process each line independently) Input Output Escape Unescape Copy Output Clear Escape Sequence Reference How to Use Select a mode — choose the target language or format from the buttons above. Paste input — enter the raw string you want to escape (or an already-escaped string to unescape). Escape / Unescape — click the appropriate button; the result appears instantly on the right. Bulk mode — when enabled, each line of input is escaped/unescaped independently, making it easy to process lists of strings. Copy Output — copies the result to your clipboard with one click. What Each Mode Handles JSON — ", \, /, control chars, unicode (\uXXXX) JavaScript / TypeScript — single & double quotes, backtick, \n \t \r \0, unicode Python — single & double quotes, \n \t \r \\ \0, raw-string awareness Java / C# — standard C-style escapes plus unicode \uXXXX SQL — single-quote doubling, backslash mode toggle HTML — named entities: & < > " ' XML — same five entities as HTML, strictly per XML spec CSV — field quoting, embedded quote doubling, newline handling Regex — escapes all regex metacharacters: . * + ? ^ $ { } [ ] | ( ) \ Related Tools JSON Formatter HTML Entity Encoder URL Encoder Related Tools Case Converter Character Counter Regex Cheatsheet ...

Caesar Vigenere XOR AES-256 Caesar cipher shifts each letter by a fixed number of positions in the alphabet. The same shift is used for both encryption and decryption (just use the inverse). Non-letter characters are preserved unchanged. Shift (1–25) 13 Mode Encrypt Decrypt Input Text 🔒 Run Caesar Clear Result Encrypted 📋 Copy Vigenere cipher uses a keyword to apply a different Caesar shift to each character. The keyword repeats to match the input length. Only letters A–Z and a–z are shifted; everything else passes through unchanged. Keyword Mode Encrypt Decrypt Input Text 🔒 Run Vigenere Clear Result Encrypted 📋 Copy XOR cipher applies a bitwise XOR between each character and the repeating key. Applying the same key twice restores the original — so Encrypt and Decrypt are identical operations. Output is Base64-encoded to stay readable. Key (any text) Mode Encrypt Decrypt Input Text 🔒 Run XOR Clear Result Encrypted 📋 Copy AES-256-GCM via the browser's native Web Crypto API. A random 96-bit IV is generated per encryption; ciphertext is stored as iv:ciphertext in Base64. Decryption automatically extracts the IV. Your password never leaves the browser. Password Mode Encrypt Decrypt Input Text 🔒 Run AES-256 Clear Processing… Result Encrypted 📋 Copy How Each Cipher Works Caesar Cipher The Caesar cipher is one of the oldest encryption techniques. It shifts every letter in the plaintext forward (encrypt) or backward (decrypt) by a fixed number of positions in the 26-letter alphabet. A shift of 13 is the special case known as ROT13 — applying it twice returns the original text. Digits, spaces, and punctuation are left unchanged. ...
