FAQ
Is Base64 encryption?+
No. Base64 is encoding, not encryption — anyone can decode it. Never use it to protect secrets.
Does it handle Unicode / emojis?+
Yes. This tool encodes via UTF-8 so non-Latin characters and emojis round-trip cleanly.
URL-safe Base64?+
The standard alphabet uses + and /. For URL-safe variants replace + with - and / with _ before use.
