About Image to Base64

The Free Image to Base64 Converter is an easy-to-use online tool that lets you instantly convert your images into Base64 encoded strings. Whether you’re a developer, designer, or student, this converter helps you embed images directly into HTML, CSS, or JSON files without uploading them to a server — saving time, improving security, and streamlining workflow.

What is an Image to Base64 Converter?

An Image to Base64 Converter is a tool that encodes image files (like JPG, PNG, or GIF) into Base64 format — a text-based representation of binary image data. Base64 encoding allows you to store or transfer images as text, which is especially useful in web development when embedding images directly into HTML or CSS without linking external files.

For example, you can embed a Base64 string in your code instead of referencing an image file hosted elsewhere — ensuring the image always loads instantly, even offline.

How Does It Work?

Upload your image file (JPG, PNG, GIF, BMP, or SVG).
Click “Convert to Base64.”
The tool encodes your image and generates a Base64 string instantly.
Copy the string or download it as a .txt file.

No installation, sign-up, or technical setup required — it all happens online in seconds.
