Base64 Encode / Decode
Base64 is an encoding that turns text and binary data into a string of characters safe to carry inside text, links and emails. This tool encodes any text — including Arabic with full UTF-8 support — and decodes it live as you type, without your data ever leaving the browser.
How to use
- Pick the Encode or Decode tab.
- Type or paste the text into the input box.
- The result appears instantly in the output box as you type.
- Copy the result with the Copy button or reset with Clear.
Frequently asked questions
Does it support Arabic text?
Yes. Text is first converted to UTF-8 bytes and then to Base64, so Arabic, emoji and all Unicode characters work without issues.
Is Base64 a form of encryption?
No. Base64 is a representation encoding, not encryption — anyone can decode it easily, so never use it to hide sensitive information.
Where is Base64 used in practice?
Embedding images inside HTML and CSS files, email attachments, and moving binary data through text-based systems like JSON and XML.
Why do I get an invalid input message when decoding?
The text contains characters outside the Base64 alphabet or its length is misaligned. Make sure you copied the full string, including any trailing = padding characters.
