About the Base64 Encoder / Decoder
Base64 Encoder / Decoder is a free browser-based developer tool from Convertify. Encode text to Base64 or decode a Base64 string back to readable text, instantly in your browser. Everything runs instantly with no file upload, no account, and no usage limit.
Frequently Asked Questions
Is Base64 encoding the same as encryption?
No — Base64 is just a way of representing binary or text data using a safe set of 64 characters. It provides zero security and is trivially reversible by anyone, it's not meant for protecting sensitive data.
Does this handle non-English text and emoji correctly?
Yes — text is converted to UTF-8 bytes before encoding and decoded back the same way, so accented characters, emoji and non-Latin scripts round-trip correctly.
What happens if I paste invalid Base64 into the decode side?
You'll see a clear "Invalid Base64" message instead of garbled output or a silent failure.
Is anything sent to a server?
No — encoding and decoding both happen entirely in your browser using built-in JavaScript APIs.
