Frequently Asked Questions
What is a Base64 image?
A Base64 image is an image encoded in ASCII text using the Base64 encoding scheme. It can be embedded directly in HTML, CSS, or JSON without needing a separate image file.
Is my image uploaded to your server?
No. All conversions are done entirely in your browser using JavaScript. Your images are never transmitted to any server, ensuring your privacy and security.
Does the tool preserve the original image format?
Yes. When converting Base64 to image, the downloaded file will have the same format as the original image (JPG, PNG, WEBP, or SVG). The tool extracts the MIME type from the Base64 data.
Why do I need to convert images to Base64?
Base64 encoding allows you to embed images directly into HTML/CSS/JSON, reducing HTTP requests and simplifying distribution. It's commonly used for icons, small images, and email signatures.
What is the difference between plain Base64 and Data URI?
Plain Base64 is just the encoded data. A Data URI includes the MIME type (e.g., 'data:image/png;base64,') plus the Base64 string. Our tool accepts both forms.
