Frequently asked questions

Do I need the data:image prefix?

No. Raw Base64 works too. The tool reads the first bytes to tell whether it's a PNG, JPG, GIF, WebP, BMP, ICO, AVIF or SVG.

It says the Base64 is invalid. What's wrong?

Usually the string was cut off when copying. Make sure you copied all of it, including any = signs at the end. Line breaks and spaces are ignored.

Is the data sent anywhere?

No. Decoding happens in your browser with JavaScript, and nothing is uploaded.
