Text to Base64

Encode any text string into a Base64 format for safe data transmission.

The Text to Base64 encoder converts any string into its Base64 representation. Base64 is commonly used for embedding data in HTML, safely transferring data over media that only supports text, and obfuscation. Encode your text to Base64 now!

FAQ

Common questions 3 questions

What is Base64 used for?

Base64 is used to encode binary data (like images or encrypted keys) into a plain text format, making it safe to transmit over protocols (like email or HTTP) that only reliably handle text.

Is Base64 an encryption method?

No, Base64 is an encoding scheme, not encryption. It makes data look unreadable, but it's easily reversible and provides no security.

Does Base64 make the data smaller?

No, Base64 encoding actually increases the size of the data by about 33% because it represents every 3 bytes of data with 4 characters of text.
