Base64 Encode / Decode
Unicode-safe in both directions.
FAQ
What is Base64?
An encoding that represents binary data using 64 safe ASCII characters — used in data URLs, email attachments, and APIs (like ours: PDFs travel as Base64 at api.calcwhale.com).
Is Base64 encryption?
No. It's encoding, not encryption — anyone can decode it. Never use it to hide secrets.
Does it support emoji and non-Latin text?
Yes, we encode via UTF-8 first, so any Unicode text round-trips correctly.
