DEDICATED TOOL PAGE

Base64 encode or decode plain text.

Convert regular UTF-8 text to Base64 for testing and debugging, or decode a Base64 string back into readable text. This is a small but common developer task, and it benefits from a direct page.

PRACTICAL NOTES

Encoding is not encryption.

Use it for representation

Base64 makes binary or special text easier to move through systems that expect plain text, but it does not protect the underlying content.

Decode with caution

If a pasted Base64 string turns into unreadable output, it may contain binary data rather than plain text.

Pair with URL encoding carefully

Base64 and URL encoding solve different problems. Use the one that matches the transport or storage requirement in front of you.

Common questions

Can Base64 recover the original text exactly?

Yes, as long as the input is valid and represents plain text. It is a reversible encoding format, not a one-way transform.

Should I use Base64 for secrets?

No. Base64 hides nothing from anyone who decides to decode it.
