The subject can finally scoot over
Version 1.0.6The Rounded Corners preview now lets you zoom in and drag the image until the important part sits exactly where it should.
Added
A 100–250% zoom slider, mouse and finger dragging, double-click recentering, and arrow-key nudging.
Kept sensible
Zoom and position belong to one image, so they reset when you choose another instead of following you around like an uninvited plus-one.
Download behavior
The saved file keeps the original pixel dimensions. Zooming simply crops the outer edges you moved beyond the frame.
Still private
Framing, previewing, and downloading all happen locally in the browser. The image never leaves your device.
