Base64 Encoder

Base64 Encoder is a free, browser-based tool from SmartTools. Encode and decode Base64 text.

3. The result updates instantly in your browser as you work.

Are my files safe with Base64 Encoder?

Does Base64 Encoder work on mobile?

Base64 Encoder works entirely inside your browser using client-side code. We do not upload, copy, store or share your files, text or results, and we keep no logs of what you process here. Because processing happens on your device, results depend on your browser and device capability, and the tool is provided as-is without warranty for critical, legal or financial use — please check important output yourself. Some tools that need live data (currency rates, translation, network checks) send only the minimum request needed to a public third-party service. Use SmartTools only with content you own or have permission to edit. Questions or takedown requests: bahaigamarbhola@gmail.com.
