Frequently asked questions
Why convert an image to Base64?
▾
Base64-encoded images can be embedded directly in HTML (<img src="data:image/png;base64,...">) or CSS (background-image: url(...)), eliminating an HTTP request. Useful for small icons and inline email images.
Does Base64 increase file size?
▾
Yes. Base64 encoding increases size by approximately 33% because it represents 3 bytes of binary data as 4 ASCII characters. Use it for small images; for large images, serve them as separate files.
Is the image uploaded to a server?
▾
No. The conversion runs entirely in your browser using the FileReader API. Your image data never leaves your device.
