Common questions
Does it handle Unicode?
Text is encoded via standard UTF-8 → Base64. Emoji and non-Latin scripts are supported.
Is Base64 encryption?
No. It is encoding only — anyone can decode it. Never treat it as security.
File uploads?
Designed for text in the browser. Large binary files may be impractical in-tab.
