Convert an image into Base64, a data URL, or CSS url() output directly in your browser.

PNG, JPG, WebP, GIF, SVG, and other browser-readable images are supported.
Convert an image to Base64 when you need to embed a small asset in HTML, CSS, JSON, an email template, a test fixture, or an API payload without referencing a separate image file.
Choose the right Base64 output
- Data URL includes the image MIME type and can be used in an HTML
srcattribute. - Raw Base64 contains only the encoded bytes for APIs or storage fields that supply the type separately.
- CSS url() wraps the data URL for direct use in a stylesheet declaration.
When should an image be embedded?
Embedding can simplify a self-contained demo, small icon, offline document, or generated fixture. Base64 does not compress the image and usually makes the encoded data about one third larger than the original file. Large photos and frequently reused assets are normally better served as separate cacheable files.
The original image bytes are preserved; changing the output type does not resize or recompress the image. Reading, previewing, copying, and saving happen locally in your browser.
