Image to Base64
Turn an image into a Base64 data URI you can paste directly into CSS or HTML.
Your files never leave your device. All processing happens in your browser.
How to use
Upload an image and copy the generated Base64 data URI.
How it works
The browser reads the file and encodes its bytes as a Base64 data URL.
Frequently asked questions
What is a data URI good for?
