Photos go soft for small reasons: heavy compression, a slight resize, a lens that missed perfect focus by a hair. Sharpening works by increasing contrast along edges, which is exactly what the eye reads as “sharp” — it does not invent detail, but it makes the detail you have stand out.

Drag the amount slider and watch the preview: 30–50% suits most photos, higher values start adding halos around edges and grain in flat areas. The honest limit is worth stating plainly — sharpening cannot rescue a badly blurred photo, because no tool can create detail that was never captured. For that, you need a sharper original.

For overall photo improvement rather than edge sharpness, the photo filters (brightness, contrast, clarity-style presets) are the better starting point.

Frequently asked questions

Can sharpening fix a blurry photo?
Only slightly soft photos. Sharpening boosts edge contrast; it cannot invent detail that was never captured, so badly blurred photos stay blurred.
How much sharpening should I use?
30–50% for most photos. Above that, halos appear around edges and flat areas get grainy.
Does sharpening change DPI or size?
No. Pixel dimensions and DPI metadata stay the same; only edge contrast changes.
Is my photo uploaded?
No. Everything runs in your browser; your photo never leaves your device.
