How Image to Base64 works
Choose an image

Convert
The tool reads the file locally and encodes it as a Base64 data URL.
Copy the data URL
Copy the result to embed the image directly in HTML, CSS or JSON without hosting a separate file.
Frequently asked questions
Why would I convert an image to Base64?
Embedding a small image as a Base64 data URL can avoid an extra HTTP request, which is useful for icons, inline emails or self-contained HTML snippets.
Does this upload my image to a server?
No. The file is read and encoded locally using your browser's FileReader API; the image never leaves your device.
Is Base64 a good fit for large images?
Base64 encoding increases file size by roughly a third, so it works best for small images rather than large photos.
