How to Convert Image to Base64
Encoding images allows you to embed them directly into HTML or CSS, reducing HTTP requests. Follow these steps:
- Upload: Select any image file (JPG, PNG, SVG).
- Generate: The tool instantly processes the file locally and creates the Data URI string.
- Copy: Click "Copy Code" to use it in your
<img src="...">or CSSbackground-image.
Performance & Best Practices
Base64 encoding increases file size by approximately 33%. To maintain website performance, follow these guidelines from Google Developers:
- Small Images Only: Use Base64 for icons, logos, or tiny UI elements (under 10KB).
- Reduce Size First: Before converting, use our Resize Image Tool or Crop Image Tool to minimize the payload.
- Avoid Large Photos: For large banners, standard image files (WebP/JPG) served via CDN are better.
Learn more about Base64 Encoding on Wikipedia or check the technical specs on MDN Web Docs.
Frequently Asked Questions
Is my image uploaded?
No. The conversion happens 100% in your browser using JavaScript. Your files never leave your device.
Why is the code so long?
Base64 represents binary image data as text. Complex images result in very long strings. Use the "Download .txt" button for easier handling.
