Frequently asked questions
If your input looks like valid Base64 and decodes to readable UTF-8 text, it is decoded; otherwise it is encoded. This covers the common cases without a manual toggle.
Yes. Encoding and decoding are UTF-8 safe, so emoji, accents and other Unicode characters round-trip correctly.
Base64 is an encoding, not encryption — it is trivially reversed and provides no security. Never use it to protect sensitive data.
Base64 represents binary or text data using a 64-character ASCII set, which is why it shows up in data URLs, email attachments, JWTs and API payloads.
This tool encodes text to Base64 and decodes it back, picking the direction for you. It is UTF-8 safe, so international text and symbols convert without corruption.
