🔒 100% private — files are processed locally in your browser, never uploaded.
How to use

- The Base64 data URI is generated instantly.
- Copy the raw data URI, the HTML <img> tag, or the CSS background-image rule.
Frequently asked questions
What is Base64 encoding used for?
Base64 turns binary image data into plain text, letting you embed images directly inside HTML, CSS, JSON or emails without a separate file request.
When should I NOT use Base64 images?
Base64 output is about 33% larger than the binary file and cannot be cached separately. It is best for small icons and logos under ~10 KB, not for photos.
Is my image sent to a server?
No — the FileReader API in your browser does the encoding. The image and its Base64 text never leave your device.
