Image to Base64

Every so often a project needs an image as a string instead of a file — a quick prototype, an email template, a CSS background, a code snippet. That is what this image to Base64 converter is for. Upload a file, get back either the raw Base64 string or the full data URI, ready to paste straight into your code.

The plain Base64 string is the encoded payload, useful when you want to handle the decoding yourself. The data URI format — data:image/png;base64,... — slots directly into an <img src>, a CSS background-image, or the body of an email template. Either way, the image travels inline with the document instead of living at a separate URL.

A Base64 encoder is fine for small icons and illustrations. For anything larger than a few kilobytes, inline embeds start to hurt more than they help — your HTML balloons, and browsers cannot cache the image separately. Use this for snippets, tests, and one-off templates; use a real asset pipeline for production images.

Resize the original first with Image Resizer so the Base64 payload does not balloon. Run Image Compressor if the file is heavy. And if you need to go the other way, Base64 to Image decodes a Base64 string back into a downloadable image file.
