Frequently Asked Questions

What is Base64 used for?+
It represents binary or special-character data as safe ASCII text โ€” used in data URIs, HTTP basic auth headers, email attachments (MIME) and API payloads.
Is Base64 encryption?+
No โ€” a common and dangerous misconception. Base64 is a reversible encoding anyone can decode; it provides zero secrecy. Never use it to "protect" passwords.
Does it handle Unicode and emoji?+
Yes โ€” text is encoded via UTF-8 first, so international characters and emoji survive the round-trip correctly.
Why is the encoded string longer?+
Base64 maps every 3 bytes to 4 characters, adding about 33% size โ€” the price of text-safe transport.
