Why Convert Images to Base64?
Base64 encoding turns binary image files into ASCII text so they can be embedded directly inside HTML, CSS, JSON, or any text-based format — without needing a separate file request. This tool gives you every format you'd need in one click.
When should I use Base64 images?
Ideal for small assets: logos, icons, favicons, inline email images. Embedding cuts one HTTP request per image. For large images, it bloats payload size by ~33% — use sparingly on performance-critical pages.
What's the difference between Data URI and raw Base64?
A Data URI includes the data:image/png;base64, prefix needed by browsers. Raw Base64 is just the encoded string — useful for APIs, databases, or when you build the prefix yourself.
Is SVG supported?
Yes. SVG files are encoded and output as data:image/svg+xml;base64,.... Note: for SVG you can also use a URL-encoded version in CSS — but Base64 is universally safe and supported.
Is this tool private / does it upload files?
100% local. The FileReader API reads your image entirely in-browser. Zero network requests. Your files never leave your device.
