Frequently asked questions
What is a Base64 image?
Base64 encodes image bytes as ASCII text. Useful for embedding images directly in HTML/CSS/JSON without a separate file. Small icons and inline SVGs benefit most.
Should I always use Base64 for images?
No. Base64 images are ~33% larger than the original file and cannot be cached separately. Best for tiny icons under 5 KB. Larger images should stay as separate files.
Which output format should I pick?
Data URL for JavaScript. CSS background for stylesheets. HTML img for direct embedding. Raw Base64 if you need just the encoded string.
Is my image uploaded?
No. All conversion runs in your browser. Images never leave your device.
