Base64 Encoder
Encode text to Base64 format. Convert plain text to Base64 encoded string instantly.
About Base64 Encoder
The Base64 encoder converts text into its Base64 representation, the standard way to encode data so it survives transport through systems that only handle ASCII text.
Base64 encoding turns binary or non-ASCII data into a text-safe string used in data URLs, API payloads, email attachments, and authentication tokens. This encoder produces a correct, standard result with optional UTF-8 handling.
When to Use Base64 Encoder
Use it to embed small images in HTML via data URIs, to encode credentials or tokens for APIs, or to package binary data into JSON.
Pro Tip
Base64 is encoding, not encryption — anyone can decode it. Never use it to 'protect' passwords or secrets.
