Base64 encoder and decoder
Convert any text to Base64 for URLs, tokens, data URIs or email headers — or bring Base64 back to readable text. The tool handles Unicode correctly, including Arabic characters and emojis, and switches between encode and decode with one click. Everything runs locally in your browser: nothing is transmitted or stored anywhere.
How to use
- Paste your text (or Base64 string) into the input box.
- Choose Encode or Decode with the toggle buttons.
- The result appears instantly in the output box.
- Click "Copy" to take it to your clipboard.
- Toggle the direction and convert as many times as you need.
Why use Outilverse?
A Base64 tool that handles Unicode correctly — most online encoders mangle Arabic text and emojis. It also runs privately in your browser, so tokens and secrets inside your text never touch a server.
FAQ
Does it support Arabic and emojis?
Yes. The tool encodes UTF-8 correctly, so Arabic text, emojis and mixed scripts all round-trip exactly.
Is Base64 encryption?
No — Base64 is an encoding, not encryption. Anyone can decode it; never rely on it to protect passwords.
Is my data uploaded anywhere?
Never. Encoding and decoding happen entirely inside your browser.
