💻 Image to Base64 Converter

Base64 encoding converts binary image data into ASCII text, allowing images to be embedded directly in HTML, CSS, JavaScript, JSON, or XML files without needing a separate image file. Common uses: email HTML templates, CSS background images, favicon embedding, offline web apps, and API payloads.

Convert your image to Base64 using this tool, select 'HTML img tag' output mode, copy the result, and paste it directly into your HTML. The resulting tag looks like: . No separate image file needed.

A Data URI includes the MIME type prefix: data:image/jpeg;base64,[string]. Raw Base64 is just the encoded string without the prefix. Use Data URI for HTML src attributes and CSS. Use raw Base64 when an API or service expects just the encoded data.

Yes — Base64 encoding increases file size by approximately 33% compared to the original binary image. This is a trade-off accepted for the convenience of embedding images directly in code. For performance-critical web pages, use file references instead of Base64 for large images.

Scroll to the 'Base64 → Image' section of this tool, paste your Base64 string or full Data URI, and click Preview & Download. The image renders immediately and downloads as a PNG file.
