Image to Base64 FAQs
Why use Base64 for images?
Embedding images as Base64 (Data URIs) reduces the number of HTTP requests required to load a page, which can improve loading speed for small icons and assets.
Are there size limitations?
While you can encode large images, Base64 strings are typically about 33% larger than the original binary file. It is best used for small assets like icons or logos.
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.
