About Base64 Encode & Decode
Base64 is the standard way to turn binary data or special characters into plain text that can travel safely through emails, URLs and APIs. Developers use it to embed images in code, pass tokens around, and store binary data in text files.
This page encodes and decodes Base64 text instantly, with proper Unicode support - so emoji, Urdu, Chinese and other non-English text survive the round trip, unlike older tools that break on anything beyond plain English letters.
How to use it
- Paste your text, or a Base64 string you want to decode.
- Press Encode to Base64 or Decode from Base64.
- Copy the output, or download it as a text file.
Frequently asked questions
What is Base64 used for?
Base64 turns binary data into plain text so it can be embedded in HTML, CSS, JSON, emails and URLs without breaking. It is not encryption - anyone can decode it.
Does it handle emoji and Urdu text?
Yes. Encoding uses UTF-8, so emoji, Urdu, Arabic, Chinese and every other script encode and decode correctly.
Why does decoding fail sometimes?
Usually because the string has missing characters, extra spaces in the wrong place, or is not Base64 at all. Check that you copied the full string.
Is my text uploaded?
No. Encoding and decoding run entirely in your browser.
