Base64 Encode / DecodeEncode text to Base64 or decode Base64 back to text (UTF-8 safe).Hash Generator (MD5, SHA-256)Generate MD5, SHA-1, SHA-256, SHA-384, SHA-512 and CRC32 hashes of any text at once.URL Encode / DecodePercent-encode text for URLs or decode %20-style strings.HTML Entities Encode / DecodeEscape characters like < > & " as HTML entities, or decode entities back to text.Text to Binary ConverterConvert text to binary code (01001000) and binary back to text.Text to Hex ConverterConvert text to hexadecimal and hex back to text.Morse Code TranslatorTranslate text to Morse code and Morse code to text.Base64 EncodeEncode text or strings to Base64 online, UTF-8 safe (emojis and accents work).Base64 DecodeDecode Base64 (standard or URL-safe) back to readable text.URL EncodePercent-encode text for safe use in URLs and query strings.URL DecodeDecode percent-encoded URLs (%20, %C3%A9…) back to readable text.Base32 Encode / DecodeEncode text to Base32 (RFC 4648) or decode Base32, e.g. for 2FA/TOTP secrets.Base32 EncodeEncode text to Base32 (RFC 4648 alphabet A–Z, 2–7).Base32 DecodeDecode Base32 strings back to text.Base58 Encode / DecodeEncode or decode Base58 (Bitcoin alphabet, no 0/O/I/l), used for crypto addresses and short IDs.Base85 (Ascii85) Encode / DecodeEncode or decode Ascii85 / Base85, the compact encoding used in PDF and PostScript.Base36 Encode / DecodeConvert big integers to compact Base36 strings (0-9a-z) and back, e.g. for short IDs.Unicode Escape / UnescapeConvert characters to \uXXXX escape sequences and back, for JavaScript, Java and JSON.Punycode Converter (IDN)Convert international domain names to Punycode (xn--) and back.Text to ASCII CodesConvert text to ASCII / Unicode code points (decimal, hex, octal) and back.MD5 Hash GeneratorGenerate the MD5 hash (checksum) of any text. MD5 is fine for checksums but not for passwords.SHA-1 Hash GeneratorGenerate the SHA-1 hash of any text, e.g. for Git-style checksums.SHA-256 Hash GeneratorGenerate a SHA-256 hash of text, the standard for integrity checks and signatures.SHA-384 Hash GeneratorGenerate a SHA-384 hash of text, e.g. for Subresource Integrity (SRI).SHA-512 Hash GeneratorGenerate a SHA-512 hash of any text.HMAC GeneratorCreate HMAC-SHA256 / SHA-512 signatures with a secret key, e.g. to test webhook signatures.CRC32 ChecksumCalculate the CRC32 checksum of text (hex and decimal).ROT13 / Caesar CipherEncode or decode ROT13 and Caesar cipher text with any shift.
