# **Image Base64 Encode**

Convert images to Base64 strings in bulk

**Image file (multiple)**

**Drop image here**or click to select an image

## What is Image Base64 Encode?

Image Base64 Encode is a tool for converting image files into Base64 text. The result can be viewed as raw Base64, a Data URI, an HTML `**img**` tag, or a CSS `**background-image**`, depending on how you want to use it.

It is useful when you want to embed small images directly into HTML or CSS, or when you need to handle image data as text. The tool also supports multiple files, so you can review several results in the browser at once.

## How to Use

1. Add image files by selecting them or dragging and dropping them into the tool.
2. Review the generated Base64 result.
3. Choose the output format you need.
4. Copy the result and use it where needed.

You can process up to 20 images at once, which makes the tool useful for comparing or reviewing several files together.

## Output Formats

### Base64 (Raw Data)

This is the Base64 string without a Data URI prefix. It is useful when you need only the raw encoded body for an API or custom processing.

### Base64 (with Data URI)

This includes the `**data:image/...;base64,**` prefix. It is useful when you want the result to work directly as an image source in the browser.

### HTML img Tag

This outputs the result as an `**<img src="..." />**` tag. It is convenient when you want to paste the result directly into HTML.

### CSS Background Image

This outputs the result as `**background-image: url("...");**`. It is useful when you want to paste the result into CSS.

## Details You Can Check

For each result, the tool also shows an image preview and basic file information.

- File name
- Last modified date
- Height
- Width

That makes it easier to review not only the encoded text, but also the original image details at the same time.

## Use Cases

- Embedding small images directly into HTML or CSS
- Creating image data in Data URI format
- Handling image payloads as text for APIs or JSON
- Reviewing Base64 output for multiple images at once

## Things to Keep in Mind

- Base64 output becomes much longer than the original binary data, so large images can be cumbersome to handle
- This approach works best for small embedded assets; larger images may be better kept as regular files
- Very large images can make browser-based display and copying heavier
