What is Base64 Image Encoding?
Base64 encoding converts binary image data into a text string that can be embedded directly in HTML, CSS, or JSON. This eliminates separate HTTP requests for small images like icons and logos.
Common Use Cases
- Inline Images in HTML —
<img src="data:image/png;base64,..."> - CSS Backgrounds —
background: url(data:image/png;base64,...) - JSON API Responses — Embed images directly in JSON payloads
- Email Signatures — Self-contained images without external hosting
FAQ
Is this secure? Yes. All processing is done locally in your browser. No files are uploaded anywhere.
What's the size limit? Images up to 10MB work well. Base64 increases file size by ~33%, so very large images are better served as separate files.
