What is an image to Base64 data URL?

An image Base64 data URL is a text-based representation of the image's binary data, prefixed with its MIME type and encoding method, allowing you to embed the image directly in HTML or CSS.

Is my image uploaded to a server for Base64 conversion?

No. The conversion occurs entirely within your local browser memory using the FileReader API. Your image never leaves your device and is not sent to any external server.

Which image formats can be converted to Base64?

All common image formats are supported, including PNG, JPEG, WEBP, SVG, GIF, and ICO.

How does Base64 encoding affect image file size?

Base64 encoding increases the textual representation size by roughly 33% compared to the original raw binary file size.

Can I use Base64 for very large images?

While technically possible, embedding large Base64 strings in HTML or CSS is not recommended because it increases document sizes and can degrade page rendering performance.
