About Image Base64 Encoding

Converting images to Base64 strings allows you to embed them directly in HTML, CSS, or JSON without separate image files. This is useful for small icons (under 10KB), email templates, and reducing HTTP requests. The trade-off is a ~33% increase in data size compared to the binary original.

Frequently Asked Questions

What image formats are supported?
PNG, JPG/JPEG, GIF, SVG, WebP, ICO, and BMP. Any image format your browser can display.
Is there a file size limit?
No hard limit, but Base64 encoding increases size by ~33%. Images over 10KB are generally not recommended for Base64 embedding.
Is my image uploaded to a server?
No. All conversion happens entirely in your browser. Your images never leave your device.
