Free Base64 Encoder / Decoder
Convert plain text to Base64 and decode Base64 strings back to text instantly. Safe and secure client-side conversion.
What is Base64 Encoding?
Base64 is a binary-to-text encoding schema that represents binary data in an ASCII string format. It translates binary information into a radix-64 representation using 64 safe characters: A-Z, a-z, 0-9, +, and /. The character '=' is used as a padding indicator at the end of the encoded string.
Base64 is widely used when data needs to be transferred over channels that are designed to handle only text, such as sending emails (MIME format), embedding images in HTML/CSS, or transferring keys in XML/JSON APIs.
Is Using This Online Base64 Tool Safe?
Yes! Unlike online tools that send your input to cloud servers for processing (risking exposure of passwords, keys, or private text), this Base64 Encoder / Decoder processes everything strictly inside your local browser. No internet connection is needed for the conversion, ensuring absolute privacy.
