🔡 Image to Base64

About this Image to Base64

The Image to Base64 tool encodes a picture as a text string that can be embedded directly in HTML, CSS or JSON. Small icons and logos are often inlined this way so a page needs no extra image request. The encoding runs in your browser; the image itself is never sent anywhere.

How to use it

1. Choose an image from your device.
2. Wait a moment while it is encoded as a data URL.
3. Click Select All to highlight the full string.
4. Copy it and paste it into your code or document.

Example

A 12 KB PNG icon becomes a data URL you can paste into a CSS background-image, so the icon loads with the stylesheet.

Frequently asked questions

How much bigger is Base64 than the file?

About 33% larger than the original binary file, because every 3 bytes become 4 text characters.

When should I use Base64 images?

For small images like icons and logos. Large photos are better kept as normal files because the text gets huge.

Is the encoding reversible?

Yes, Base64 is an encoding, not compression or encryption. Anyone can decode it back to the original image.
