Why use this tool?
Data URLs allow you to inline images directly within your markup or stylesheets, eliminating the need for separate image file requests. This is especially useful for icons, small UI elements, and email templates where external hosting is impractical. Upload your file and the generator produces a properly formatted data: URL with the correct content type header. Your image is processed entirely within your browser, so it is never uploaded to any server or seen by imgic. The generated URL can be used anywhere that accepts standard image references.

Frequently asked questions
What is the difference between a data URL and a Base64 string?
A data URL is a complete URI that includes the scheme (data:), MIME type, encoding declaration, and the Base64 payload. A raw Base64 string is just the encoded data without the URI wrapper. Data URLs are ready to use directly in src attributes and CSS url() functions.
Is my file private and secure?
Completely. Your file is processed 100% inside your browser using the Web APIs built into your device. Nothing is uploaded to any server — imgic never sees, stores, or transmits your images. You can even use these tools offline once the page has loaded.
Which formats work with data URL generation?
All browser-supported image formats work, including JPEG, PNG, GIF, WebP, SVG, and BMP. The generator reads the file’s MIME type and includes it in the output URL automatically.
Can I use data URLs in CSS background properties?
Absolutely. Paste the generated data URL inside a CSS url() declaration, such as background-image: url(data:image/png;base64,...). This approach is commonly used for small repeating patterns and UI sprites.
Are there browser compatibility concerns with data URLs?
Data URLs are supported by all modern browsers including Chrome, Firefox, Safari, and Edge. Some older browsers impose size limits on data URLs, so keeping the source image small ensures the widest compatibility.
