About the image to base64 converter

Image to Base64 Converter is a free online tool that lets you turn an image into a base64 data URI you can paste straight into code in seconds. Everything happens locally inside your browser, so your files and text never leave your device and nothing is ever uploaded to a server. That makes it a safe choice for private, sensitive or work documents — and it also means the tool stays fast even on a phone or a slow connection. There is no account to create, no email to hand over, no daily limit and no watermark on anything you produce. It's built for web developers and email template builders who need a reliable result right now, then want to get on with their day.

How it works

  1. 1. Drop your file into the box above (or tap to browse).
  2. 2. Adjust the options if you want a different result.
  3. 3. Press “Convert to base64” — processing happens on your device.
  4. 4. Download or copy your result instantly. Nothing is stored anywhere.
