About Base64 to Image Converter

The Base64 to Image Converter turns encoded Base64 text and data URLs back into real, downloadable image files right inside your browser. Paste a string copied from HTML, CSS, JSON, or an API response and instantly preview the decoded picture before saving it.

Because the decoding is done locally with JavaScript, nothing is ever uploaded to a server. That keeps confidential graphics private while giving you a fast, install-free way to extract images from code or data.

Frequently Asked Questions

Do I need to include the data:image prefix? ▼

No. You can paste a complete data URL such as data:image/png;base64,iVBOR... or just the raw Base64 characters. The tool detects and handles both automatically.

What image format will the download be? ▼

The converter preserves the format encoded in the string, so a PNG stays a PNG and a JPG stays a JPG. The format is read from the data URL header when present.

Are my Base64 strings sent to a server? ▼

No. Decoding runs entirely in your browser with JavaScript, so your data and the resulting images never leave your device.

Can I decode very long Base64 strings? ▼

Yes. You can decode strings of any length your browser can handle, though very large images may take a moment to render on slower devices.
