Image to Base64 Converter

Convert Any Image to a Base64 Text String

This free tool turns a picture file into a Base64 string you can paste directly into your HTML or CSS. Base64 is a way of representing binary image data using only plain text characters, so the image travels as part of your code instead of as a separate file that the browser has to download.

To use it, choose an image from your device and the tool produces the encoded text along with a ready-to-use data URI such as data:image/png;base64,.... You can drop that string into an img tag, a CSS background-image rule, or an email template.

When Inline Base64 Helps

Embedding small images this way removes an extra network request, which can speed up the first paint of icons, logos, and tiny graphics. It is best for small files, since Base64 increases the byte size by roughly a third and large strings make your code harder to read. For photographs and big assets, a normal linked file is usually the better choice. Everything runs in your browser, so your image is processed on your own device.
