The essentials

Image data, ready to use

Move image data between a file and the formats commonly used in web development.

01 / ENCODE

What is Base64?

Base64 is a way to represent binary data as text using a set of 64 characters. It lets image data travel in text-based formats such as HTML, CSS, and JSON.

02 / CONVERT

How does conversion work?

Your browser reads the selected image and encodes its bytes as Base64. For decoding, the tool turns valid Base64 data back into image bytes and previews them.

03 / USE

When should I use a Base64 image?

Embedding a small image can reduce separate requests, but it increases text size and can’t be cached independently. For larger images, a regular image file is often more efficient.
