Base64 Image Encoder

What is Base64 Image Encoding?

Base64 image encoding is a method of converting binary image data into a text string using the Base64 ASCII character set. This allows you to embed image data directly into text-based files like HTML, CSS, or JSON, rather than linking to an external image file.

Key Features

Client-side processing: Your images are never uploaded to a server.

Supports all common image formats (PNG, JPG, GIF, SVG, WebP).

Generates ready-to-use HTML and CSS snippets.

Displays file size and dimensions.

Instant conversion.

How to Use

Click the file input or drag and drop an image.

Wait for the conversion to process instantly.

Copy the raw Base64 string, the HTML <img> tag, or the CSS background property.

Paste the code into your project.

Common Mistakes

Encoding very large images: Base64 increases file size by ~33%, which can slow down page loads.

Not optimizing images before encoding: Always compress your images first.

Using Base64 for everything: It's best for small icons, logos, or critical UI elements.

Use Cases

Embedding small icons in CSS to avoid extra HTTP requests.

Including images in standalone HTML files (e.g., email signatures).

Storing image data in JSON or databases.

Quickly previewing image data.
