Image to Base64 Converter

About This Tool

Look, I get it—sometimes you just need to turn an image into Base64. No fancy UI, no subscriptions, no nonsense. This tool does one thing: takes your image and spits out a Base64 string. That’s it. Whether you’re embedding an image directly into HTML, CSS, or a data URL, this saves you a few minutes of copy-pasting from some sketchy online converter.

I built this because I got tired of uploading random screenshots to third-party sites just to get a string I could paste into my code. Privacy matters. Your images never leave your browser. They’re processed right there on your machine. No servers. No tracking. Just you, your image, and a clean output.

Key Features

• Works entirely in your browser—no uploads, no data sent anywhere.
• Supports JPEG, PNG, GIF, and WebP formats. Basically everything you’d actually use.
• Instant conversion. Drop the file, get the string. No waiting.
• Copy to clipboard with one click. Because manually selecting long strings is a pain.
• Lightweight. No frameworks, no bloat. Just vanilla JS doing its job.
• Works offline. Once the page loads, you don’t need internet.

FAQ

Why would I even need Base64 for an image?
Honestly? Mostly for embedding. Say you’re building a tiny HTML email template and don’t want to host images. Or you’re injecting a logo into a CSS file. Base64 lets you include the image data directly in your code. It’s not always the best choice—file size increases by about 33%—but sometimes it’s the simplest fix.

Is it safe to use?
Yeah. Your image never gets uploaded. The conversion happens in your browser using the FileReader API. Nothing leaves your device. I don’t collect stats, I don’t track you, and I definitely don’t store your files. If you’re paranoid (and you should be), open DevTools and watch the network tab—nothing happens.
