What is Image to Base64?
Base64 is a way of encoding binary data (like an image) as plain text. Developers use
this to embed small images directly inside HTML, CSS or JSON — as a data:
URI — instead of linking to a separate file. This avoids an extra network request for
small icons, inline logos, or email-safe images that need to work without external
image hosting.
How to Use This Tool
- Upload the image you want to convert.
- The full Base64 data URI appears instantly in the text box.
- Click Copy to Clipboard and paste it directly into your HTML/CSS/JSON.
