FAQ
What is Base64?
A way of writing binary/text data using only 64 safe characters (A-Z, a-z, 0-9, +, /) — so data travels safely through emails, URLs, and JSON without corruption. This is NOT encryption, anyone can decode it.
Will non-English text/emoji encode correctly?
Yes — the tool is UTF-8 safe. Text like "नमस्ते" or emoji encodes correctly and decodes back accurately. Simple btoa()-based tools often fail here.
Why am I getting an error on decode?
The input isn't valid Base64 — it has invalid characters or the wrong length. Check that the full string was copied, not just part of it.
Is it safe to store passwords in Base64?
Absolutely not! Base64 is encoding, not encryption — anyone can decode it in a second. Passwords should use hashing (bcrypt) instead.
