About encoders & decoders
Base64, Base32, Base58, hex, URL and 30+ other encodings. This collection has 37 free tools, including Base64 Encode & Decode, URL Encode and Decode, UTF-8 Encoder & Decoder, Binary Code Translator, Hex to Text Converter and more. Encodings turn data into a different alphabet so it can travel safely through systems that only accept certain characters. Base64 is the best known, but dozens of others exist, each with its own trade-off between size, readability and safety.
This tool does one encoding well. It shows the result as you work, reports clear errors for invalid input and never sends your data anywhere.
