Frequently Asked Questions
Why convert an image to Base64?+
Base64 encoding lets you embed images directly in HTML, CSS, or JSON without separate file requests. Useful for small icons, email templates, and reducing HTTP requests.
Is my image uploaded to a server?+
No. The conversion happens entirely in your browser using the FileReader API. Your image never leaves your device.
Is there a size limit?+
There's no hard limit, but Base64 increases file size by ~33%. It's best for small images (under 50KB). Large images should be served as files instead.
