Decode Base64 to text
Paste a Base64 string to restore readable text. Whitespace is ignored. Use URL-safe mode if your string uses - and _ instead of + and /. Decoding stays on your device.
Examples

FAQ
- Why does decoding fail?
- The string may be truncated, use URL-safe alphabet, or not be Base64. Try toggling URL-safe and remove any surrounding quotes.
- Can I decode JWT payload segments?
- Many JWT parts are URL-safe Base64 without padding. Enable URL-safe and paste that segment only.
