Base64 rewrites arbitrary text or binary data using a 64-character alphabet so it can travel safely through systems that only accept text. DeskDazzle encodes and decodes on your device, which is the only sensible place to do it: Base64 is not encryption, and anything you paste into a remote encoder has been handed over in readable form.
How to encode or decode Base64
Paste your text or your Base64 string into the input.
Pick a direction — encode to Base64, or decode an existing Base64 string.
Copy the result, or download it if the output is large.

Questions
Is Base64 a form of encryption?
No, and this is the mistake worth avoiding. It is reversible by anyone with no key at all — it hides nothing. Use the password and encryption tool if you need actual secrecy.
Why does the output end in "=" signs?
Padding. Base64 works in three-byte groups, and the trailing equals signs mark input that did not divide evenly into them.
Is my input sent anywhere to be encoded?
No. Encoding and decoding both happen in your browser, which is what makes it safe to paste something you would not paste into a remote tool.
