Key features
- Encodes JPG, PNG, WebP, GIF, and BMP to Base64 right in the browser
- Toggle between a full data URL (with data:image/…;base64, prefix) and raw Base64
- Shows original byte size and encoded character length
- Copy to clipboard or download the string as a .txt file
- No upload — encoding runs through FileReader on this device only
Common use cases

Things to know
