How to Use the Image to Base64 Converter
Drag and drop an image onto the upload area, or click to select a file. The tool instantly converts your image to a Base64-encoded data URI string.
You get three ready-to-use output formats: the raw Base64 data URI, an HTML <img> tag, and a CSS background-image property. Click "Copy" next to any format to copy it to your clipboard.
Supported formats include PNG, JPG, GIF, SVG, WebP, and ICO. All processing is done locally via the FileReader API — your images never leave your device.
Frequently Asked Questions
Why would I embed an image as Base64?
Base64-encoded images can be embedded directly in HTML or CSS, eliminating an extra HTTP request. This is useful for small icons, logos, or email templates where external image hosting is inconvenient.
Does Base64 increase file size?
Yes, Base64 encoding increases the data size by about 33%. It's best used for small images (under 10 KB). For larger images, linking to an external file is more efficient.
Is my image uploaded to any server?
No. The conversion uses the browser's FileReader API. Your image stays on your device and is never sent anywhere.
