Frequently asked questions

What is Base64 encoding?

Base64 converts text or binary data into a safe ASCII alphabet (A–Z, a–z, 0–9, + and /), which is handy for embedding data in URLs, JSON, HTML or email.

Is my text or data uploaded to a server?

No. The Base64 Encoder / Decoder runs entirely in your browser using JavaScript — nothing you type or paste is sent anywhere, and everything disappears when you close the tab.

Is this tool free to use?

Yes, completely free with no sign-up, no watermarks and no usage limits. Base64 Encoder / Decoder is part of a collection of free tools where new tools are added after review.

Does it work on phones and tablets?

Yes. The layout is fully responsive and all processing is done on your device, so it works on any modern phone, tablet or computer — even offline once the page has loaded.
