How to Use Image to Base64 Converter
To convert an image to Base64, upload your image file by clicking the upload area or dragging it onto the page. The tool reads the file in your browser and generates a Base64-encoded data URL immediately. No server upload takes place.
The output panel shows the complete data URL string (e.g. data:image/png;base64,...) along with ready-to-use HTML and CSS code snippets. You can copy the data URL directly to embed the image in HTML img tags, CSS background properties, or JavaScript code without needing a separate image file.
Frequently Asked Questions
What is an image Base64 data URL? expand_more
A Base64 data URL encodes an image's binary data as a text string and embeds the image type. It allows images to be included directly in HTML, CSS, or JSON without referencing an external file.
When should I use Base64 encoded images? expand_more
Base64 is useful for small icons, logos, or frequently used images that you want to inline to reduce HTTP requests. For large images, file references are better because Base64 encoding increases data size by about 33%.
Does Base64 encoding increase file size? expand_more
Yes. Base64 encoding increases the data size by approximately 33% compared to the original binary file, because it encodes 3 bytes as 4 characters.
What image formats can be converted to Base64? expand_more
The tool supports JPG, PNG, GIF, SVG, and WebP images. The output data URL includes the correct MIME type for each format.
Can browsers display Base64-encoded images directly? expand_more
Yes. All modern browsers support data URLs in img src attributes, CSS background-image properties, and JavaScript Image objects.
