Frequently asked questions
What's the difference between sharpening, unblurring, and upscaling?
Sharpening increases local contrast at edges on an otherwise decent photo. Unblurring reconstructs structure from genuine optical blur. Upscaling rebuilds detail when resolution is too low. Pick by symptom: slightly soft → sharpener; visibly smeared → unblur; too small → upscaler. When unsure, all three are free to try.
Will sharpening create visible edge artifacts or halos?
Cheap sharpening does; ours is designed not to. Halos appear when every edge gets identical amplification regardless of strength. Magnitude-aware processing applies correction in proportion to real edges, which keeps jawlines and horizons clean.
Does this work well on text-heavy images like documents and screenshots?
Yes — text edges respond dramatically to proper sharpening. For screenshots degraded by messaging-app re-compression specifically, see our screenshot quality fixer which covers that pipeline end to end.
Can I control how much sharpening is applied?
The current version applies one calibrated automatic amount chosen to avoid artifacts across typical photos. Fine-grained manual strength control may come later; we prefer shipping one honest default over a slider most people misuse.
