Is my data sent to a server?

No. This tool runs entirely in your browser. Your data never leaves your browser.

Does this use standard or URL-safe Base64?

Encoding uses standard Base64. Decoding accepts standard Base64 input (you can paste typical API or config values).

Paste or upload text for UTF-8 encoding. For arbitrary binary, use a dedicated file workflow — this tool targets text.
