Frequently Asked Questions
What can I encode or decode?
You can convert Base64 strings, URL components, and common HTML entities in either direction.
Does Base64 encrypt my data?
No. Base64 is an encoding format, not encryption. Anyone with the encoded value can decode it.
Can I convert Unicode text?
Yes. The tool handles regular Unicode text through UTF-8 compatible browser processing.
Is my input saved?
No. Conversion happens locally and your input is not stored on a server.
