# Image to Base64

> Turn images into a Base64 data URI to embed them directly in HTML, CSS, email templates or JSON. No upload.

Small icons or a logo in an HTML email can be written straight into the code as a data URI, without a separate image file. The result is a text file starting with "data:image/…".

- Open in browser: https://pockettoolbox.org/en/image-to-base64
- Tool: [All-In-One File Converter](https://pockettoolbox.org/en/file-converter)
- Runs entirely in your browser; files and input are never uploaded.

## How it works

1. Drop the image in. Base64 is set.
2. Convert and open the text file. Use its content directly as src or url().

## FAQ

### Is it worth it for large images?

No. Base64 makes the data about a third larger, and the browser cannot cache it separately. It is good for icons under a few kilobytes.
