Why convert an image to Base64?
Base64 is an encoding algorithm that transforms any binary data (like an image file) into a long string of ASCII text. By embedding this text directly into your HTML markup (using the <img src="..."> tag) or your stylesheet (using background-image: url(...)), the browser can render the image immediately without having to make an extra HTTP request to fetch the file from the server. This technique is fantastic for optimizing load times for small icons, logos, or loading spinners.
Image to Base64 FAQ
Are my images uploaded to your servers?
No. We take your privacy seriously. The conversion happens entirely locally inside your browser using the native HTML5 File API. Your image files never leave your device.
Is there a file size limit?
Technically no, but we strongly recommend keeping files under 2MB. Encoding very large, high-resolution images into Base64 creates enormous text strings that can bloat your CSS/HTML files, hurting your website's performance rather than helping it. It's best used for small graphical assets.
