Base64 Data URL

About this Tool

Tired of managing countless small image files? Our Image to Base64 converter transforms any image into a single line of text that you can embed directly in your code. This is the secret to faster-loading websites, cleaner code, and easier-to-manage assets. Perfect for developers who want to inline small icons, logos, or background images.

This tool reads your image file and uses the browser's FileReader API to create a Data URL. This URL includes the Base64-encoded version of your image, which can be used directly in web pages.

  1. Drag and drop your image or click to upload.
  2. Instantly see a preview of your image on the left.
  3. The Base64 data URL will be generated automatically on the right.
  4. Click 'Copy' to grab the entire string and paste it into your HTML or CSS.
  • Embedding a logo directly into an email signature.
  • Inlining small icons in a CSS file to reduce server requests.
  • Storing image data within a JSON file for a web application.
  • Supports All Major Formats: Works with PNG, JPEG, GIF, SVG, and more.
  • Instant Preview: See your uploaded image immediately.
  • Ready-to-Use Output: Generates a complete data URL for `src` attributes or CSS `url()`.
  • Improves Performance: Reduces HTTP requests by inlining small images.
  • 100% Secure & Private: All conversions happen in your browser. Your images are never uploaded.

Data URLs (defined in RFC 2397) allow content to be embedded in web pages as if they were external resources. Base64 is the encoding scheme used to convert the binary image data into a text format that can be included in the URL.

Why should I use Data URLs?

They are great for small images because they eliminate the need for an extra server request, which can speed up page load times.

Does this increase the file size?

Yes, Base64 encoding increases the size of the data by about 33%. It's best used for small images where the overhead is less than the cost of an HTTP request.

Is it supported in all browsers?

Yes, Data URLs are supported by all modern web browsers.

All calculations and data processing for this tool are performed locally in your browser. We do not send any of your data to our servers, ensuring your information remains private and secure.
