Frequently asked questions

      

        
Is my image uploaded?

        
No. The file is read with the browser's FileReader API and never leaves your device.

        
Why is the output so long?

        
Base64 expands binary data by roughly 33%. For that reason it suits small icons and sprites, not large photos.

        
Which formats work?

        
Anything your browser can load as an image — PNG, JPEG, GIF, WebP and SVG are all fine.
