Base64 Encode / Decode — free online tool

Encode UTF-8 text for Basic auth headers or decode Base64 payloads from webhooks—handles Unicode safely in the browser.

Useful when you want a quick answer without pasting sensitive data into random chat bots.

How to use Base64 Encode / Decode

Paste UTF-8 text into Base64 Encode / Decode.
Choose encode to get Base64, or decode if you already have a payload.
Run and copy the output—watch for padding characters at the end when decoding.
Avoid encoding huge binaries here; use file tools for large assets.

Practical tips

Base64 is encoding, not encryption—anyone can decode it, so never hide secrets this way.
Expect output ~33% larger than the input; it is for transport, not compression.
This handles UTF-8 safely, so non-Latin text round-trips without corruption.

Limitations

Base64 Encode / Decode runs on text in your tab only—there is no cloud save, version history, or collaboration. Copy results before closing the page.
