What is Image to Base64?
Encode any image as a Base64 data URI so you can embed it directly in HTML or CSS without a separate file. Upload an image to get the data URL, a complete <img> tag and a CSS background rule, each with a copy button. Best for small icons and inline assets.
How Image to Base64 works
The file is read with FileReader.readAsDataURL(), producing a string like data:image/png;base64,iVBORw0... that browsers treat as an image source.
Base64 adds about 33% size, so it's best for small images where avoiding an extra request matters.
Common uses
- Embed small icons inline in HTML or CSS
- Avoid an extra image HTTP request
- Paste images into emails or data files
- Generate a data URI for testing
Frequently asked questions
What is a Base64 image?
An image encoded as text (a data URI) that can be embedded directly in HTML or CSS instead of a separate file.
When should I use it?
For small images like icons. Large images become bloated and slow as Base64.
Is it private?
Yes — encoding happens in your browser; the image is never uploaded.
