Passwords & encoding

Password generator, Base64, URL encoding, UUIDs and hashes — everything runs in your browser and nothing is sent anywhere.

7 tools

• Password generator

  Create a strong random password between 4 and 64 characters long from letters, numbers and symbols. It's generated in your browser and never sent anywhere.

• UUID generator

  Generate one or many UUIDs (GUIDs) — version 4 (random) or version 7 (time-ordered). Everything is generated in your browser.

• Hash generator

  Hash any text with MD5, SHA-1, SHA-256, SHA-384 and SHA-512 at once. Your text never leaves your browser.

• Base64 encoder and decoder

  Encode text to Base64 or decode Base64 back to text. Works with any UTF-8 text, emoji and the URL-safe variant.

• URL encoder and decoder

  Percent-encode text for use in a URL (%20 for a space) or decode a URL full of %XX sequences back into readable text.

• Morse code translator

  Translate text to Morse code or decode dots and dashes back to text — letters, numbers and punctuation.

• Caesar cipher

  Encrypt or decrypt text with a Caesar cipher using any shift, including ROT13.
