Encode text to Base64
Convert text to Base64 without sending it to a server.
What to know
Text is encoded as UTF-8 first, then Base64, so non-Latin scripts and emoji survive the round trip. Base64 grows the data by about a third.
Base64 is an encoding, not encryption. Anyone can decode it instantly — it exists to move binary data safely through text-only channels, not to hide anything.
Questions
Is anything uploaded to a server?
No. Every tool on this site runs inside your browser using standard web APIs. There is no upload, no account, no logging and no server holding your data afterwards. You can confirm it by opening your browser's developer tools and watching the network tab stay empty while you work.
Is Base64 secure?
No. It provides no protection whatsoever and is trivially reversible. Use it for transport, never for secrecy.
