About the base64 encoder
Base64 Encoder is a free online tool that lets you encode any text into Base64 safely in your browser in seconds. Everything happens locally inside your browser, so your files and text never leave your device and nothing is ever uploaded to a server. That makes it a safe choice for private, sensitive or work documents — and it also means the tool stays fast even on a phone or a slow connection. There is no account to create, no email to hand over, no daily limit and no watermark on anything you produce. It's built for writers, students, developers and content creators who need a reliable result right now, then want to get on with their day.
How it works

- 2. Adjust the options if you want a different result.
- 3. Press “Encode to Base64” — processing happens on your device.
- 4. Download or copy your result instantly. Nothing is stored anywhere.
