Question 1

What is Base64 image encoding?

Accepted Answer

Base64 encoding converts binary image data into an ASCII string using 64 characters. It allows images to be embedded directly in HTML, CSS, or JSON as Data URLs without separate file requests.

Question 2

Is my image uploaded to any server?

Accepted Answer

No. All conversion happens entirely in your browser using the FileReader API. Your images never leave your device.

Question 3

What image formats are supported?

Accepted Answer

PNG, JPG/JPEG, GIF, SVG, WebP, BMP, and ICO are all supported. The tool automatically detects the MIME type and generates the correct Data URL prefix.
