How do I convert an image to Base64?

Simply upload your image file to the Base64 Image Converter tool, and it will automatically generate the Base64 encoded string. You can then copy the code or download it for use in your projects. The conversion happens instantly in your browser without sending files to any server.

What image formats are supported by this converter?

The Base64 Image Converter supports all common image formats including PNG, JPG, JPEG, GIF, WebP, BMP, and SVG. You can use the tool with any standard image file format used on the web.

Can I use Base64 images in HTML and CSS?

Yes, absolutely. You can embed Base64 images directly in HTML using the img tag with a data URI (data:image/png;base64,...) or in CSS as background images. This method reduces server requests and is useful for small images, icons, and logos.

Is Base64 encoding secure for storing sensitive images?

Base64 encoding is not encryption—it's simply a text representation of binary data. While it obscures the image from casual viewing, it provides no security. For sensitive images, you should use proper encryption methods in addition to Base64 encoding.

Why is my Base64 image larger than the original file?

Base64 encoding increases file size by approximately 33% because it uses more characters to represent the same binary data. This overhead is why Base64 is best used for small images. For large files, traditional image linking is more efficient than Base64 embedding.
