You can use this tool to convert PNG to Base64, JPG to Base64, JPEG to Base64, WebP to Base64 and GIF to Base64.

When to Use a Base64 Image
Base64 image encoding can be convenient for small graphics that you want to embed directly into HTML or CSS instead of referencing a separate image URL. Keep in mind that Base64 adds text overhead, so ordinary image files can be more efficient when served as separate cached assets. For larger photos and production websites, compare file size and page performance before embedding them as Data URIs.

What Is Base64 Image Encoding?
Base64 encoding represents binary image data as text characters. A Base64 Data URI combines the media type with the encoded data, allowing the image to be referenced directly inside HTML or CSS. For example, a web developer can use an image Data URI in an HTML image element or as a CSS background image without creating a separate image URL.
Frequently Asked Questions
How do I convert an image to Base64 online?
Upload your image, let the browser encode it, then copy the generated Data URI, CSS background code, or HTML image tag.
Can I convert PNG to Base64?
Yes. PNG files are supported, along with JPG, JPEG, WebP and GIF images.
Can I convert JPG or JPEG to Base64?
Yes. Upload a JPG or JPEG image and the tool generates a Base64 Data URI and copy-ready code.
Can I use the Base64 result in CSS?
Yes. The CSS output is provided as a background-image data URL that you can copy into a stylesheet or inline style.
Are my images uploaded to a server?
The current converter uses the browser FileReader API to read the selected image and generate the Base64 result locally. As with any online tool, avoid entering confidential files or sensitive information.
Is Base64 always smaller than an image file?
No. Base64 generally increases the size of binary data, so it is most useful when embedding small assets is more convenient than managing a separate file.
