Upload an image above to generate its Base64 encoded Data URL — no server, 100% in your browser.
The Image to Base64 Encoder converts any image — PNG, JPEG, GIF, WebP, SVG, or BMP — into a Base64-encoded Data URL entirely inside your browser. No file is ever uploaded to a server. Use the output directly in HTML src attributes, CSS background-image rules, or embed images in JSON and CSS without extra HTTP requests.
A Data URL encodes a file's binary content as a Base64 ASCII string prefixed with its MIME type (e.g. data:image/png;base64,...). Browsers can use it anywhere a regular URL is accepted, letting you embed images directly in HTML or CSS without a separate file request.
Base64 encoding represents every 3 bytes of binary data as 4 ASCII characters, adding roughly 33% overhead. A 100 KB PNG becomes about 133 KB as Base64 text, which is a normal and expected trade-off when embedding images inline.
The encoder accepts any format your browser can read via FileReader: JPEG, PNG, GIF, WebP, SVG, BMP, TIFF, ICO, and AVIF. The resulting Data URL preserves the original MIME type automatically.
No. The entire conversion happens locally in your browser using the FileReader API. Your image never leaves your device, making this tool safe for sensitive or private images.
