Base64 Generator
Encode text to Base64 or decode Base64 back to readable text for tests, APIs, payloads and technical workflows.
Conversion happens in your browser. No text is sent to servers.
Result
Local processing: this tool does not send, save or log your input.
Quick answer
This generator encodes text into Base64 and decodes Base64 back to UTF-8 text. It accepts text, JSON, short payloads and technical values, then shows the result to copy or download.
How to use the Base64 generator
Choose encode or decode, paste the input into the main field and click convert. Use copy to reuse the result in APIs, tests, documentation or developer tools.
Available options
The tool lets you switch between encoder and decoder, use a sample, swap input and output, copy the result, download a TXT file and clear the form.
How conversion works
Base64 turns bytes into an ASCII representation. For text, this tool uses UTF-8 before encoding and TextDecoder when decoding, preserving accents and special characters.
Practical example
Input: Novemax online tools. Base64 output: Tm92ZW1heCBvbmxpbmUgdG9vbHM=. When you decode that value, the original text appears again.
How to interpret and reuse the result
Base64 does not encrypt data: it only represents bytes as transport-safe text. Use it for payloads, examples, small data URIs and compatibility, not to hide sensitive information.
Useful tips
Check whether the Base64 value kept trailing characters such as =. For large files, prefer local tools or dedicated libraries to avoid browser slowdowns.
Frequently asked questions
Is Base64 encryption?
No. Base64 is reversible encoding, not a security method. Anyone can decode the content.
Can I decode text with accents?
Yes. The tool uses UTF-8 to encode and decode special characters correctly.
Is my data sent to a server?
No. Conversion happens in your browser and the page does not send the input to servers.
Why can Base64 end with an equal sign?
The = sign is padding used when the byte count does not complete full encoding groups.
