How to Use Image to Base64 Converter

The Image to Base64 Converter is a free online tool that converts image files into Base64 encoded strings. Upload a PNG, JPEG, GIF, WEBP, or SVG image up to 5 MB and get the Base64 data URI string instantly. Base64 encoded images can be embedded directly in HTML, CSS, or JavaScript without requiring separate file requests, which can improve page load performance for small images. Use it for embedding icons in CSS, including images in email templates, storing images in JSON data, or reducing HTTP requests. All conversion happens in your browser — your images are never uploaded to any server.

Step-by-Step Instructions

  1. Click to upload or drag and drop an image file (PNG, JPEG, GIF, WEBP, or SVG)
  2. Wait for the image to be converted to Base64 format
  3. View the Base64 encoded string in the output area
  4. Copy the data URI string for use in your HTML, CSS, or JavaScript
