What Is Image to Base64?
Base64 encoding turns a binary image into plain text so it can be embedded directly in HTML, CSS or JSON. This free online tool converts your picture into a data URL instantly and shows the file size plus the full encoded length, so you know exactly what you are about to paste.
When to use it
- Inlining small icons directly in CSS or HTML
- Embedding images in JSON or API payloads
- Sharing an image as text in chat or a support ticket
- Avoiding extra image requests on a landing page
FAQ
- Is this Base64 converter free? Yes, it is completely free and you can convert as many images as you like.
- Why is the Base64 string longer than the file? Encoding adds about a third in overhead, so a 30 KB image becomes roughly 40 KB of text.
- Does my image get uploaded? No, the conversion uses your browser's FileReader and the data never leaves your device.
