Image Base64 Encode

What is Image Base64 Encode?

A simple and convenient tool for converting image files into Base64 encoded strings. Base64 encoding allows you to handle images as text format and embed them directly into HTML or CSS.

Since the conversion process is completed entirely in the browser, images are never uploaded to any server, ensuring fast processing while maintaining your privacy and security.

Main Uses of Image Base64 Encode

Base64 encoded images are particularly useful in the following scenarios:

• Reducing HTTP Requests: Embed small images directly into HTML or CSS to reduce additional server requests
• API Data Communication: Convenient for exchanging images via JSON in REST APIs instead of binary data
• Offline Usage: Create self-contained content without requiring external file references

How to Use Image Base64 Encode

Basic Usage

1. Click the "Select File" button or drag and drop the images you want to convert
2. Images are automatically encoded and results are displayed
3. Select the desired format (Raw, DataURI, HTML, CSS)
4. Use the copy button to copy the encoded data

You can convert up to 20 images at once (conversion will not be performed if more than 20 images are selected).

Processing Time

For large images, the conversion process and copy operations may take some time. Please wait until the process completes.

Output Format Options

The encoded data can be output in four different formats depending on your needs:

Base64 Data (Raw Data)

Pure Base64 encoded string without Data URI declaration (e.g., data:image/png;base64,). This format is suitable for APIs or custom implementations.

iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAA...

Base64 Data (with DataURI Declaration)

Outputs in Data URI format that browsers can directly interpret. This starts with the data: scheme and specifies the MIME type and Base64 encoding.

data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAA...

HTML img tag

Outputs as an HTML img tag that you can directly paste into a web page.

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAA..." alt="Base64 Encoded Image">

CSS Background Image

Outputs as a CSS background-image property that you can use in CSS files or style attributes.

background-image: url('data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAYAAAAf8/9hAAAA...');

Image Data Details

In the lower section of the encoding results, you can view the preview of the converted image along with the following information:

• Image Name: Original file name
• Last Modified: File's last update time
• Dimensions: Image resolution (in pixels)
• File Size: Comparison between original image size and size after Base64 conversion

This information is particularly helpful when processing multiple images at once to identify each image.

Important Notes

• Base64 encoding increases the size by approximately 33% compared to the original binary data
• Base64 encoding of large images may impact performance, making it most suitable for small to medium-sized images
• Very large Base64 strings may not be processable due to browser limitations
