Convert an image to Base64 online

Generate a Base64 string or Data URI from an image and quickly copy it for HTML, CSS, JSON or development workflows.

What is Base64 image encoding?

Base64 represents binary file data as text characters. A Data URI combines the MIME type and the encoded data so it can be embedded directly into supported HTML or CSS contexts.

About Image to Base64

Read an image as Base64 text or a data URI for small embeds. Create data URI text for a small icon or a quick coding example, then copy only what you need.

How the browser tool works

The browser reads the selected image bytes and encodes them as Base64 text. That text is longer than the binary source and can make HTML or CSS unwieldy for large pictures. Files are processed in the browser workspace; compare the preview and the actual downloaded result.

How to use it

  1. Choose a supported source file in the workspace above.
  2. Adjust the available options and inspect the preview or settings.
  3. Process the image and examine the downloaded file at its intended size before publishing.

Limits and privacy

Base64 text is larger than the binary file and is poor for large images.

The workspace works locally in your browser; selected source images are not sent to this site's application server. Some features load third-party code from a CDN, and large images may run out of device memory. Keep a backup of your original.

Questions about Image to Base64

Is Base64 an image compression method?

No. It is a text representation of bytes and normally adds overhead.

Does it change my source file?

No. The browser creates a separate result for download. Keep the original if you may need another adjustment.
