What is Base64 encoding actually used for?

It's a way to represent binary data as plain text, commonly used for embedding images directly in HTML/CSS, encoding data in URLs, or passing binary data through systems that only handle text safely.

What is this tool?

Encodes text or data into Base64 format, or decodes Base64 back into its original form — a common encoding used to safely represent binary data as plain text, often seen in data URLs, email attachments, and API tokens.

How to use it

Paste your text or Base64 string, select encode or decode, and the converted result appears immediately.

Base64 encoding is not encryption — it's a reversible format for safely representing data as text, so don't rely on it to keep anything actually secret or secure.
