FAQ

When is image to Base64 actually useful?

It is most useful when you need to embed a small image directly into HTML, CSS, an email template, documentation, or a quick prototype.

Are there drawbacks compared with a normal image file?

Yes. Base64 increases string size and is often inefficient for larger images, so it is usually best for smaller assets.

Should I use plain Base64 or a Data URL?

If you need to place the image directly into `src` or CSS, a Data URL is usually more convenient. Plain Base64 is better when another system expects only the encoded string.

Is the image uploaded to a server during conversion?

No. Conversion happens locally in the browser.
