Encode text to Base64 (UTF-8 safe).

Result appears here after you select

{ } How to use

  1. Paste or type the text you want to encode.
  2. Select Process, then copy the Base64 or download it.

{ } How it works

Base64 Encode works on the text you provide. Select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.

Input

  • Text input — paste or type your input in the left panel (use Sample for an example)

Output

TXT text — copy or download it from the Output panel.

{ } Common uses

  • Embed a small file or image in CSS, HTML or a data URI.
  • Carry byte-like data through a JSON string, a URL or an email header, all of which expect text.
  • Pass a value through a system that would otherwise mangle raw bytes.

{ } Limitations

  • The result is about a third larger than the input, because Base64 writes every 3 bytes as 4 characters. Use it for text-safety, never to save space.
  • The text is read as UTF-8 and the standard alphabet is used — not the URL-safe variant that writes - and _ in place of + and /.

{ } FAQ

Is my data uploaded to a server?

No. Everything runs locally in your browser — your files never leave your device.

Can I process more than one file at once?

This tool works on one input at a time.

Is this tool free?

Yes — it’s completely free and needs no sign-up.

Is Base64 encryption?

No. It is fully reversible and needs no key, so anyone can decode it instantly. Never use it to hide a secret.
