Questions
Is Base64 encryption?
No. Anyone can decode Base64; it only turns data into plain letters and digits so it travels safely through text-only systems.
Does it handle emoji and non-English text?
Yes, text is encoded as UTF-8, so Urdu, Arabic, Chinese and emoji survive the round trip.
Is my data uploaded?
No. The tool runs in your browser; what you paste or open never leaves your device and nothing is stored on a server.
