About img64.dev

img64.dev is a free, privacy-focused tool for converting images to Base64 format. Built for developers, by developers.

Why We Built This

Every time I needed to convert an image to Base64, I'd search for an online tool and wonder: "Is this site stealing my files?"

Most tools require uploads to their servers. Some are covered in ads. Many are slow or bloated with unnecessary features.

So I built img64.dev with a simple principle: your images never leave your browser.

How It Works

  • 100% Client-Side — All conversion happens in your browser using JavaScript
  • No Server Uploads — Your images never touch our servers
  • Works Offline — Once loaded, the tool works without internet
  • Multiple Formats — Data URI, Base64, CSS, HTML, JSON
  • Dark Mode — Easy on the eyes

Who Is This For?

Web developers, email designers, API developers, and anyone who needs to embed images as text. Common use cases include:

  • Inline CSS background images
  • Email signature images
  • API payloads
  • Prototyping and demos
  • Embedding small images in HTML/CSS

The Tech Stack

Built with modern web technologies:

  • Next.js 14 — React framework
  • Tailwind CSS — Styling
  • TypeScript — Type safety
  • Vercel — Hosting
