Key facts

  • Runs entirely in your browser via JavaScript|Uses the standard Base64 alphabet (A-Z, a-z, 0-9, +, /)|No file upload or server round-trip involved|Free with no usage limit|Base64 output is roughly 33% longer than the original input

What is this tool?

This tool encodes text into Base64 format, useful for embedding data in JSON, URLs, or other text-based formats that require Base64-encoded content.

How to use it

Type or paste your text; the Base64-encoded result appears instantly, ready to copy.
  1. Enter the text you want to encode.|The tool instantly displays the Base64-encoded result.|Copy the encoded output.

Example

Example: encoding the text "Hello" produces the Base64 string "SGVsbG8=".

How it works

The page uses the browser's built-in Base64 encoding functions (such as `btoa`) to convert your input text's bytes into the standard Base64 character set, entirely in your browser.

Common use cases

Encoding credentials or tokens for use in an API request header.|Embedding text data in a URL or JSON payload.|Learning or testing how Base64 encoding works.|Preparing data for systems that specifically require Base64 format.

Benefits

Free, instant, and requires no software installation.

Limitations

Base64-encoded output is roughly 33% longer than the original input; this tool encodes text, not arbitrary binary files (use a dedicated file-to-Base64 tool for files).

Privacy & your data

Encoding happens entirely in your browser using JavaScript's built-in Base64 functions. Your input text is not sent to or stored on the A2Z Tools server.

Frequently asked questions

Is Base64 encoding secure?

No. Base64 is a reversible encoding, not encryption. Anyone can decode it instantly, so never use it to hide passwords or secrets.

Does Base64 encoding make my text longer?
Yes. Base64-encoded output is roughly 33% longer than the original input text.
Why is Base64 output longer than my input?

Base64 represents every 3 bytes of input with 4 output characters, so encoded data is roughly 33% larger, plus optional = padding.

Can I encode files, not just text?
This tool is designed for encoding typed or pasted text; for files, a dedicated file-to-Base64 converter is more appropriate.
Does this tool support Unicode text?

Yes — input is treated as UTF-8, so emoji and non-Latin scripts encode and decode correctly.

Is my text sent to a server?
No. Encoding happens entirely in your browser; your input is not sent to or stored on the A2Z Tools server.
Is this tool free to use?
Yes, it's free with no signup required.
