image to base64 converter

Convert any image file into a Base64-encoded string instantly.

Image to Base64 Converter transforms image files such as PNG, JPEG, GIF, WebP, and SVG into Base64-encoded text strings. Base64 encoding allows you to embed images directly into HTML, CSS, or JSON without needing separate image file hosting, which is particularly useful for email templates, single-page applications, and data URIs.

This tool is invaluable for developers who need to inline small icons or logos in stylesheets, embed images in API payloads, create self-contained HTML documents, or prepare image data for storage in databases that only accept text. It eliminates the need for external hosting for small assets.

Simply upload your image using the file picker, and the tool instantly reads the file, generates the Base64 representation, and displays a preview of the uploaded image alongside the encoded string. You can then copy the entire Base64 string to your clipboard with a single click.

All processing happens entirely in your browser using the FileReader API — no image data is uploaded to any server. Your files remain completely private and secure. The tool is free, requires no account, and works on all modern browsers and devices.
