About

About base64go.

base64go.com is a free, fast, and private Base64 encoder and decoder. We built it because every other Base64 tool on the web is either ugly, slow, filled with ads, or secretly sending your data to a server. We wanted something better.

Our Principles

100% Client-Side

Every encode and decode operation runs entirely in your browser using JavaScript. No data is ever uploaded to any server. We cannot see, access, store, or log anything you type or upload.

100% Client-Side

Your data stays on your device. We believe utility tools should be clean, fast, and trustworthy. No accounts, no sign-ups - just open the page and start working.

Fast & Modern

Built with Astro and Tailwind CSS for sub-second page loads. Live encoding and decoding means you see results as you type - no buttons, no waiting.

Who Built This

base64go was built by a developer who got tired of copying Base64 strings into sketchy websites that looked like they hadn't been updated since 2012. The goal is simple: make the best Base64 tool on the internet, keep it free, and respect user privacy.
