What formats does this support?

Any image format a browser can render: JPG, PNG, WebP, GIF, SVG, AVIF, and more. If you paste a raw Base64 string without a data URI prefix, the tool sniffs the magic bytes to detect the format.

Is my data sent to a server?

No. Everything runs locally in your browser — no Base64 string or decoded image ever leaves your device.

Why would I have a Base64 image string?

Base64 images appear in HTML/CSS source code (as data: URIs), in JSON API responses, in email source code, and in database BLOBs. This tool lets you decode and preview them without writing any code.

What if the preview looks broken?

A broken preview usually means the Base64 string is incomplete (cut off), contains stray whitespace or line breaks in the wrong place, or has an incorrect MIME type prefix. Try pasting the full string again.
