Image to Base64 Converter

What is Base64?

Base64 is a binary-to-text encoding scheme that represents binary data (like an image) in an ASCII string format. It’s commonly used to embed image files directly into web pages without separate file requests.

Here’s an example:

<img src="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA..." />

Instead of linking to an image file, the data is embedded directly. This can improve performance in specific cases, especially when dealing with inline styles, emails, or small assets.

Why Use Base64 Image Encoding?

Here are some practical benefits:

  • ✅ Inline Embedding – Embed images in HTML, CSS, or JS without extra HTTP requests.
  • ✅ Useful for Emails – Ensure images are always visible in HTML emails.
  • ✅ Works Offline – Great for PWAs (Progressive Web Apps) and local demos.
  • ✅ Quick Copy/Paste – Avoid file uploads and hosting for small icons or logos.
