What can you do with these Encoders & Decoders?

Encoders & Decoders collects every conversion tool on this site for turning text and data into coded formats and back again. All tools run directly in your browser, so they work on Windows, Mac, Android and iPhone with nothing to install.

• Encode for the web: percent-encode URLs and query strings, or escape special characters into HTML entities so code displays correctly on any page.
• Base64 and Base32: encode text into Base64, decode Base64 strings, or work with Base32 formats used in tokens and configs.
• Binary and Morse code: convert text to binary, read binary back as text, or translate messages into Morse code.
• Classic ciphers: encode text with ROT13 and decode it back — a favorite for puzzles and hiding spoilers.

Use the search box above to find a tool by name or task — for example "base64", "url", "binary" or "morse". New encoder and decoder tools are added regularly.
