What is Image to Base64?

Convert any image file (PNG, JPG, GIF, SVG, WebP) to a Base64-encoded data URI string that you can embed directly in HTML, CSS, or JavaScript. This eliminates the need for separate image file requests, which can improve performance for small images like icons and logos. Upload your image and get both the raw Base64 string and a ready-to-use data URI with the correct MIME type.

How to Use Image to Base64

  1. 1Click the upload area or drag and drop an image file (PNG, JPG, GIF, SVG, WebP)
  2. 2Wait for the image to be processed (happens instantly in your browser)
  3. 3Copy the Base64 string or the complete data URI
  4. 4Paste the data URI into your HTML img tag, CSS background, or JavaScript code

Frequently Asked Questions

A Base64 data URI is a way to embed image data directly in HTML, CSS, or JavaScript as a text string instead of linking to a separate image file. The format is 'data:image/png;base64,iVBOR...' which the browser decodes and displays as an image.
Base64 encoding is best for small images (under 10KB) like icons, logos, and simple graphics. For larger images, using separate image files is more efficient because Base64 encoding increases the data size by about 33% and prevents browser caching.
This tool supports PNG, JPEG, GIF, SVG, and WebP image formats. Simply upload your image file and the tool will automatically detect the correct MIME type and generate the corresponding Base64 data URI.
