Frequently Asked Questions
Why does Google Play require flat square icons?
Google Play automatically applies its own continuous corner radius mask and drop shadow. Uploading an icon that already has rounded corners causes double-rounded borders and rejection.
Does this tool leave visible lines around extrapolated corners?
No. The engine samples clean boundary colors and fills all corner coordinates with 100% solid opacity (alpha 255), completely eliminating dark arcs and seam lines.
Are interior logo pixels altered or compressed?
No. Interior pixels are preserved 100% bit-for-bit without resampling or lossy re-encoding.
