About this tool
A 20KB limit is very tight. It is common for signature and small photo fields on application forms. A normal phone photo is far bigger than that, so this tool lowers the quality first and, if that is not enough, also makes the picture a little smaller in pixels. Your image never leaves your device.
Questions people ask
Why did my picture become smaller in pixels?+
At 20KB quality alone cannot shrink a large photo enough, so the tool also reduces its width and height until it fits.
Will a full face photo look good at 20KB?+
It will be small and a bit soft. If your form allows more, try 50KB for a clearer result.
