Decode Base64 images instantly
When working with APIs, emails, or encoded assets, you often encounter Base64-encoded images that need to be inspected. This tool decodes the string and renders the image directly in your browser.
Our decoder automatically detects the image format by analyzing the binary content (magic numbers), so it works even without a data URI prefix.
Supported formats
- PNG, JPEG, GIF, WebP
- BMP, ICO, AVIF
- Any browser-supported image format

FAQs
Why isn't my image showing?
Make sure the Base64 string is complete and not truncated. Remove any line breaks or extra whitespace. If the data isn't an image, try the generic decoder.
Do I need to include the data URI prefix?
No. The tool accepts both raw Base64 and complete data URIs like data:image/png;base64,...
Can I decode very large images?
Yes. For large images, we use Web Workers to decode in the background, keeping your browser responsive.
