Image to Base64 Encoding

Why convert images to Base64?

Base64 encoding turns your image into a text string that you can embed directly in your code. This eliminates the need for separate image files and extra HTTP requests, making your pages load faster for small images like icons, logos and UI elements.

When should I use Raw Base64 vs Data URL?

Choose based on where you'll use it:

Data URL — Use this for HTML <img> tags and CSS background-image. It includes the MIME type so browsers know how to display it.
Raw Base64 — Use this when storing in databases, sending via APIs, or when the receiving system adds its own headers.

What image formats can I convert?

This tool supports PNG, JPEG/JPG, GIF, WebP, AVIF, BMP, ICO, and SVG files.

Is there a file size limit?

Yes, files up to 5MB are supported. Keep in mind that Base64 encoding increases the data size by about 33%. For images larger than 10–20 KB, consider using regular image files instead for better performance.

Is my image data secure?

Your image never leaves your browser. All conversion happens locally on your device using JavaScript — nothing is uploaded to any server.
