What is this image to Base64 converter?
A free, browser-based tool that converts both ways between an image file and a Base64 / data: URI. Upload an image to get its data URI and raw Base64 string, plus ready-to-paste <img> and CSS background snippets — or paste a data URI to preview and download the decoded image. All processing happens locally in your browser, so your images are never uploaded.
How to use it
- Pick a direction: “Image → Base64” or “Base64 → Image”.
- Image → Base64: upload an image, then copy the data URI, raw Base64, <img> tag, or CSS background snippet.
- Base64 → Image: paste a data: URI to preview the decoded image and download it as a file.
Common use cases
- Inlining a small icon or logo into HTML/CSS to avoid an extra HTTP request.
- Embedding an image directly into an email template or a JSON payload.
- Decoding a data URI you found in source code back into an actual image file.
