I Built a Free Base64 Encoder/Decoder — No Signup, No Ads

The Problem

Every time I need to encode or decode Base64, I end up on some ad-infested site that takes 10 seconds to load.

So I built my own.

Base64 Tool

base64-eta.vercel.app

• Encode text to Base64
• Decode Base64 to text
• Copy with one click
• Works entirely in your browser — nothing sent to a server
• Free, no signup, no tracking

Tech Stack

• Next.js 14 + TypeScript
• Tailwind CSS
• Deployed on Vercel

Built as part of my free developer tools series. All tools at zero cost because developers deserve better than ad-ridden alternatives.
