Base64 encoder

Turn text into Base64. Handles emoji, ₹ and every other Unicode character correctly.

Runs in your browser. Your data is not uploaded or stored.

How to use it

  1. Paste or type your text in the input box, or upload a file.
  2. The result appears as you type. Change the options above it if you need to.
  3. Copy the result or download it as a file.

Good to know

  • Text is encoded as UTF-8 first, so non-English characters survive the round trip. Many simple encoders break on these.
  • Tick URL-safe to swap + and / for - and _ and drop the = padding. JWTs and many APIs use this form.

Questions

Is my data uploaded anywhere?
No. Everything runs in your browser with JavaScript. What you type or paste never leaves your device.
Is Base64 encryption?
No. Base64 only changes how data is written so it can travel through systems that expect plain text. Anyone can decode it, so never use it to hide passwords or secrets.

Every tool runs in your web browser. Text you paste and files you open are processed on your own device. We do not upload, store or sell them, and you do not need an account.

If you switch theme, that choice is saved in your browser so the site remembers it. Pages load fonts from Google Fonts, so your browser connects to Google’s servers to download them. We do not use advertising or tracking cookies; if that changes, this notice will be updated first.
