Question 1

What is Base64 encoding used for?

Accepted Answer

Base64 encodes binary data as ASCII text. Common uses include email attachments, data URIs, JWT payloads, and HTTP Basic Authentication headers.

Question 2

Does Base64 encrypt my data?

Accepted Answer

No. Base64 is encoding, not encryption. Anyone can decode it. Never use Base64 alone to protect sensitive information.

Question 3

Why does my decoded text show garbled characters?

Accepted Answer

The input may not be valid Base64, or it may have been encoded with a different character set. Ensure padding (=) is intact.

Question 4

Is UTF-8 supported?

Accepted Answer

Yes. The tool uses standard UTF-8 encoding/decoding, supporting international characters and emoji.
