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.
