1. What is Image to Base64?

Base64 turns an image into plain text so you can embed it directly in HTML, CSS, emails or JSON without a separate file. It is ideal for small icons and logos. Note that Base64 is about 33% larger than the original file.

2. How to use Image to Base64

Here is the whole process, step by step. It takes less than a minute from opening the tool to seeing your result.

1Upload an image.
2Choose Data URI, raw Base64, HTML or CSS output.
3Copy the result.

Your result updates as you type — there is nothing to press and nothing to wait for.

Everything runs in your browser — your files and text never leave your device.

3. What you can do with it

Switch between the modes the tool offers — "Data URI", "Base64 only", "HTML <img>", "CSS".
Save your result with the "Copy" button under the tool.

4. Tips for best results

Your text never leaves your device — The tool runs entirely in your browser using JavaScript. Nothing is uploaded, so you can paste private documents without worry. That also means there is no account to create and no file to upload.
It works on your phone too — Open the tool in any modern browser on Android or iPhone. The layout adjusts to the screen and everything works the same way on a small screen as on a desktop.
Save your result before you leave — Use the "Copy" button to keep a copy.
Pick the right option first — The tool offers "Data URI", "Base64 only", "HTML <img>", "CSS". Choose the one that matches what you need before you type, so the result comes out the way you expect.
