Encoding and decoding happen in your browser, which keeps your image files private.

Instant preview and download

Check decoded images visually and download them with the detected file type when available.

How to Use the Base64 Image Encoder

Copy the output format you need

Generate and copy the raw Base64 text, full Data URL, or ready-made HTML, CSS, JSON, and XML snippets.

Preview and download decoded images

Frequently Asked Questions

Which image formats work?

You can upload PNG, JPG, GIF, WebP, and SVG images for encoding.

Can I paste Base64 without the `data:image/...` prefix?

Yes. The decoder will try to render plain Base64 by assuming a PNG prefix if none is present.

Can I use the output in HTML emails or web pages?

Yes. The tool provides ready-to-copy Data URL and HTML/CSS snippets that can be used in many web and email workflows.

What happens if I paste plain Base64 text?

The decoder tries to render it by assuming a PNG image prefix when no data URI prefix is included.

Is this safe for private images?

Yes. Encoding and decoding happen locally in the browser, so files are not uploaded for processing.
