Frequently asked
questions
Base64 is an encoding scheme that converts binary data into a text format using 64 printable ASCII characters. It is commonly used to encode data in emails, URLs, data URIs, and APIs.
No. Base64 is encoding, not encryption. It only changes the representation of data — anyone can decode it. It provides no security. Do not use it to "protect" sensitive data.
Standard Base64 uses + and / characters which have special meaning in URLs. URL-safe Base64 replaces + with - and / with _, making the output safe to use in URLs without encoding.
