Question 1

How do I encode an image to Base64?

Accepted Answer

Select the 'Image → Base64' mode, then drag and drop an image or click to browse. The tool instantly converts it to a Base64 data URI that you can copy and paste into HTML img tags, CSS background properties, or any code that accepts data URIs.

Question 2

How do I decode a Base64 string back to an image?

Accepted Answer

Switch to 'Base64 → Image' mode and paste your Base64 string or full data URI. Click 'Decode' and the tool will display the image with its detected format. You can then download it as a file.

Question 3

Is my image data kept private?

Accepted Answer

Yes. Both encoding and decoding happen entirely in your browser using the FileReader API. Your images and Base64 data are never uploaded to any server.
