Frequently Asked Questions
This tool supports JPG, PNG, SVG, GIF, and WebP images. Upload any of these formats and you will get the Base64-encoded string and the full data URL for that file.
Copy the 'data URL' output from this tool and paste it directly as the src attribute of an img tag: <img src="data:image/png;base64,iVBORw0KGgo...">. The image loads without any external file request.
Use the data URL as a background-image value: background-image: url('data:image/png;base64,iVBORw0KGgo...'). This embeds the image directly in your CSS file with no separate HTTP request.
Yes. Base64 encoding increases file size by approximately 33% compared to the original binary file. For small icons and inline images this trade-off is worthwhile to eliminate HTTP requests, but for large images it is better to serve them as separate files.
There is no hard size limit — the encoding runs entirely in your browser. Very large images may produce a very long Base64 string that could slow down page loads if inlined in HTML or CSS. For images over 100KB, consider using an external file instead.
