About Base64EncoderDecoder.com

Base64EncoderDecoder.com is a free online tool for converting text and files to and from Base64. It was built to solve one specific frustration: most online Base64 tools send your data to a remote server. Ours doesn't.

Our mission

Give developers, students, and IT professionals a fast, reliable, and genuinely private utility for everyday Base64 work — no signup, no tracking pixels, no server round trips.

How it works

All encoding and decoding happens directly in your browser using standard Web APIs: btoa(), atob(), TextEncoder, TextDecoder, and FileReader. Your input never leaves the page. You can even disconnect from the internet after the page loads and continue using the tool.

Who builds this

Base64EncoderDecoder.com is an independent project. We're a small team of web developers maintaining the site in our spare time. If you have feedback, requests, or run into a bug, the contact page is the fastest way to reach us.
