Understanding Base64 Image Encoding
Base64 encoding is a method of converting binary image data into ASCII text format. This is useful when you need to transmit or store images in text-only environments like JSON APIs, XML files, or email bodies.
A Base64 encoded image typically looks like: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA...

Frequently Asked Questions
What is Base64 image encoding?
Base64 image encoding converts binary image data into a text string using 64 ASCII characters. This allows images to be embedded in text-based formats like JSON, XML, HTML, and CSS.
How do I decode a Base64 image?
Simply paste your Base64 string (with or without the data URI prefix) into the input area. The tool will automatically decode it and display the image. You can then download or copy the result.
What image formats are supported?
Our converter supports all common image formats including PNG, JPEG/JPG, GIF, SVG, BMP, WebP, and more. The format is automatically detected from the Base64 data.
Can I decode images with data URI prefix?
Yes! The tool accepts both raw Base64 strings and complete data URIs (e.g., data:image/png;base64,iVBORw0KG...). The prefix is automatically handled.
Is my image data secure?
Absolutely! All decoding happens entirely in your browser using JavaScript. No image data is ever sent to our servers or stored anywhere. Your privacy and security are guaranteed.
Why would I need to decode Base64 images?
Base64 encoded images are commonly used in API responses, email HTML, web scraping results, database storage, and JSON data. Decoding them allows you to view and save the actual image files.
What if my Base64 string is invalid?
The tool will display an error message explaining the issue. Common problems include invalid Base64 characters, missing padding, or corrupted data. Check that your string is complete and properly formatted.
Can I use this for large images?
Yes, but very large Base64 strings may take a moment to process. The tool handles images of all sizes, though browser memory limits may apply for extremely large files.
💡 Pro Tip
When working with Base64 images in code, remember that Base64 encoding increases file size by approximately 33%. For production websites, consider using regular image files with CDN hosting for better performance, and reserve Base64 for small icons or when embedding is necessary.
