What is Base64 image encoding?

Base64 encoding converts binary image data into ASCII text format that can be safely embedded directly in HTML, CSS, or other text-based formats without requiring a separate image file.

What image formats are supported?

This tool supports JPG, PNG, GIF, and WebP image formats with a maximum file size of 5MB.

How can I use the Base64 output?

You can use the Base64 output directly in your HTML img tags, CSS background-image properties, or any other application that accepts Base64 encoded images. The tool provides ready-to-use code snippets in both HTML and CSS formats.

Is there a file size limit?

Yes, the maximum file size is 5MB. While Base64 encoding is useful, it increases the file size by approximately 33%, so it's recommended for smaller images.

Frequently Asked Questions

Base64 encoding is a method of converting binary image data into ASCII text format. This conversion allows you to:

Embed images directly in HTML or CSS files
Send images in text-based formats (like JSON or XML)
Store image data in text-based databases
Avoid separate HTTP requests for small images

Note: Base64 encoding increases the file size by approximately 33%, so it's best used for smaller images.

This tool supports the following image formats:

JPEG/JPG - Best for photographs and complex images
PNG - Ideal for images with transparency
GIF - Suitable for simple animations and images
WebP - Modern format with superior compression

Maximum file size limit: 5MB

You can use the Base64 output in several ways:

HTML Image Tag:

<img src="data:image/jpeg;base64,YOUR_BASE64_STRING" alt="Image">

CSS Background:

background-image: url('data:image/jpeg;base64,YOUR_BASE64_STRING');

Raw Base64: Use the raw string for other applications or custom implementations

Our tool provides ready-to-use code in all these formats - just select your preferred format and copy!

Base64 encoding is best used in specific scenarios:

Small Images: Icons, logos, or small decorative elements
Single HTTP Request: When you want to reduce the number of server requests
Email Templates: When embedding images in HTML emails
Data URIs: For applications requiring data URI scheme

Not recommended for large images as it increases file size and isn't cacheable like regular image files.
