Inspect the output

Frequency suppression can soften detail or introduce ringing. Suggestions are starting points, not guarantees. This is not general noise removal, AI restoration, print-color calibration or a guarantee to remove all moiré. Output uses a resized, white-flattened working image with a maximum long edge of2048 pixels. Keep original-resolution files separately.

Your records and copies

Keep external copies before deletion or uninstalling. ZIP and JSON outputs are not editable-project restore backups. Settings may contain project names and saved treatments. File destinations depend on Android document providers. Saving does not establish recipient delivery.
