Base64 Encoder
Convert any text to Base64. Everything happens in your browser — nothing is sent to a server.
Pourquoi utiliser cet outil ?
This Base64 encoder is useful for developers who need to embed binary data (images, files) into text, JSON or URLs. Since everything runs entirely in your browser, no data is ever sent to an external server — you can safely encode sensitive information with full privacy. Fast and free, it's a handy alternative to command-line tools.
Why it's free
A discreet ad banner covers hosting costs — that's the whole business model. No account to create, no usage limit, no paid tier unlocking the real result. Calculations run in your browser, so your numbers, dates and text never leave your device.
