Base64 Encoder Online
Encode UTF-8 text into Base64.
Encode ordinary text as Base64 entirely in your browser. Paste the input, make the change, then read the result before you copy it elsewhere.
Base64 is encoding, not encryption.
Ready — input is processed locally.
This utility runs on the current device for the supported workflow. Kaazo does not need the pasted input to calculate the result.
What Base64 Encoder does — and what it doesn’t
Encode ordinary text as Base64 entirely in your browser.
Base64 is encoding, not encryption
Anyone who receives Base64 text can decode it. It’s useful for representing binary/text data in systems that expect plain characters, but it doesn’t provide secrecy.
The edge case to remember with Base64 Encoder: formatting and conversion tools can preserve valid structure, but they can't repair every ambiguous or malformed input without changing meaning. Base64 is encoding, not encryption.
The point where Base64 Encoder stops helping
Use cryptographic encryption when confidentiality is the requirement.
FAQ
What does Base64 Encoder actually do?

What is the easy mistake to make here?

Base64 is encoding, not encryption.
Does formatted or converted output prove the data is valid for my application?
No. Base64 Encoder can perform the syntax or data operation described here, but your application can still impose its own schema, business rules, encoding or security requirements.
