Free Encoding Tools
Encoding tools convert data between the formats computers and the web understand — Base64, URL encoding, HTML entities, hex and binary. These free encoders and decoders run entirely in your browser, which makes them safe for sensitive strings and tokens you’d rather not paste into a random website.

Encoding tools — questions
What’s the difference between encoding and encryption?
Encoding transforms data into another format for safe transport and is reversible by anyone. Encryption protects data so only authorised parties can read it. These are encoding tools, not encryption.
