About Base64 Encoder / Decoder
When working with binary data, image strings, or complex API structures, developers frequently encounter Base64 encoded text. Our free online Base64 encoder and decoder makes it effortless to translate raw text into Base64 format or revert a Base64 string back into readable text. With full Unicode (UTF-8) support built-in, you don't have to worry about strange symbols or broken text when converting complex data.
Using this tool as a fast Base64 to text converter is especially useful when debugging API webhooks, viewing embedded encoded emails, or testing authentication headers. Data processing is handled entirely inside your browser using native JavaScript APIs. This means your sensitive tokens and personal text strings are securely decoded without ever being uploaded to an external server.

When should I use Base64?
Use it for embedding binary data in text formats like JSON, HTML, or emails. Also used for basic data obfuscation.
Does Base64 increase size?
Yes, Base64 encoding increases the data size by approximately 33% due to the encoding overhead.
Is Base64 encryption?
No! Base64 is encoding, not encryption. It can be easily decoded by anyone. Don't use it for security.
