Tool Encode & Format
Encode, decode and format text
Paste your text, then choose what to do with it. Everything happens in your browser, so the text never leaves your computer.
About the Encode & Format
Developers constantly convert text between formats. Base64 turns any data into plain letters and digits so it can travel in email, URLs or JSON. URL encoding replaces spaces and special characters with % codes so they are safe in a web address. JSON formatting turns a compressed one-line response into readable, indented text, and minifying does the reverse.
Paste your text and choose an action. Everything runs in your browser, so tokens, API responses and other sensitive data never leave your computer. Base64 handling is UTF-8 safe, so accented letters, other scripts and emoji convert correctly.

No. Base64 only changes how data is written; anyone can decode it. Use it for transport, never to hide secrets.
