Frequently asked questions
- Is Base64 encryption?
- No. It is a reversible encoding, not encryption. Anyone can decode it, so never use it to protect secrets.
- What about URL-safe Base64?
- Standard Base64 uses plus and slash, which have meaning in URLs. URL-safe Base64 substitutes minus and underscore. Check which variant your target system expects.
- Does it handle Unicode?
- Yes. Text is treated as UTF-8 before encoding.
