Image to Base64 converter lets you encode any image into a Base64 string directly in your browser. This is useful for embedding images directly in HTML, CSS, or JSON without separate file requests.

All processing happens locally. Your images are never uploaded to any server, ensuring complete privacy and security.

Data URI Encoding

Generate complete data URIs ready to paste into your HTML img src or CSS background-image properties.

Batch Processing

Encode multiple images at once and copy all results as a structured JSON object.

Zero Upload

Files stay in your browser. No server uploads, no cookies, no tracking. Your data stays private.

How to Use

Upload one or more images using drag-and-drop, file picker, or paste.

Choose output format: raw Base64 or full Data URI.

Click "Encode All" to convert images to Base64 strings.

Copy individual results or all at once as JSON.

FAQ

Base64 is a binary-to-text encoding scheme that converts binary data (like images) into ASCII strings. It increases file size by about 33% but allows images to be embedded directly in text-based formats.

A Data URI is a URI scheme that embeds data directly in a URL string. For images, it looks like data:image/png;base64,iVBORw0KGgo... and can be used in HTML, CSS, and other web contexts.

There is no server-side limit since all processing happens in your browser. However, very large images may produce very long Base64 strings that some applications cannot handle.

No. All encoding happens locally in your browser using the FileReader API. Your images never leave your device.
