Base64 Output
What is Image to Base64 conversion?
This tool converts any image file into a Base64-encoded string, which can be embedded directly in HTML, CSS, or JSON without needing an external file. This is useful for inlining small images, storing images in configuration files, or sending image data over text-based protocols.
Output formats
- Raw Base64 — just the base64 string with no prefix. Useful for APIs, config files, or further processing.
- HTML Image — wrapped in a
<img src="data:...;base64,…">tag, ready to paste into any HTML document.
Tips
- Large images will produce very long base64 strings — for best performance, keep images under a few MB.
- SVG files are often the best candidate for base64 encoding since they're already text-based.
- All processing happens locally in your browser — your image data is never uploaded to any server.
