FAQ
Is my text sent anywhere?
No — encoding and decoding happen locally in your browser.
Can I decode arbitrary Base64?
Yes, provided it decodes to valid UTF-8 text. Binary Base64 (like images) won't display as text.
Does it support URL-safe Base64?
The standard alphabet is used; URL-safe variants can be pasted and will still decode.
