Frequently asked questions
What is Base64?
It is a way to represent binary data or text using only 64 safe ASCII characters. It is used to embed data in URLs, emails or config files.
Does it support accents and emojis?
Yes. We encode and decode with UTF-8, so accents, ñ and emojis are preserved correctly.
Does Base64 encrypt my text?
No. Base64 is encoding, not encryption: anyone can decode it. Do not use it to protect secret information.
Is my text uploaded to a server?
No. Everything is processed in your browser; your text never leaves your device.
