FAQ
Why use Base64 images?
Base64 allows embedding images directly in HTML/CSS without separate files. Useful for emails, data URIs, and APIs.
Does it increase file size?
Yes, Base64 is about 33% larger than binary. Use it only when necessary, not for large images.
What is the size limit?
Maximum 5MB images recommended. Larger images create very long strings that may slow down browsers.
Can I use this for CSS background?
Absolutely! Use format: background-image: url('data:image/png;base64,iVBORw0KGgo...');
Is it secure?
Yes! Conversion happens entirely in your browser. No image data is uploaded or stored.
