Frequently asked questions
▸What is Base64 actually for?
It turns binary data like images into plain text, so files can travel inside URLs, JSON, XML and email without getting corrupted.
▸Can it decode garbled text?
Yes, paste any Base64 string. If characters are missing or invalid, you get a clear error instead of broken output. UTF-8 round-trips perfectly.
▸Is my data stored anywhere?
No. Encoding and decoding run locally in your browser, it's free with no registration, and nothing is logged or uploaded.
