What is Blemish Remover?

Blemish Remover gives you two ways to clean a portrait: Spot Heal samples a clean source near each tap for instant single-click fixes, and Clone Stamp lets you pick the source yourself and paint over blemishes with full control. A small crosshair marks the active source, so you always see where pixels are coming from. Free and private, with up to 50 undo steps.

The clone stamp is a classic retouching tool, not an AI eraser. You pick a source pixel by Alt-clicking on a clean patch of skin — or by tapping Set Source on touch devices — then paint over the blemish; each brush stroke copies pixels from the source point, offset by the same delta you started with, into the target area, blended with a hardness curve so the seam disappears. Spot Heal mode skips the source-picking step entirely: a single tap on the blemish auto-samples a smooth patch nearby and stamps it in one click. A visible source crosshair on the canvas confirms which area is being cloned. The result looks more natural than content-aware fills because nothing is hallucinated.

How to use

1. Upload a portrait photo. Pick Spot Heal for a one-tap fix, or Clone Stamp and either Alt-click (desktop) or tap Set Source then a clean area (touch) to pick the source.
2. Paint over blemishes — the tool copies texture from the source point, blending it in naturally.
3. Adjust brush size and hardness for precision, use undo for mistakes, and download the retouched image.

When to use

• Touching up a portrait headshot for a CV, LinkedIn or company directory before printing.
• Removing a stray hair or a piece of lint from a product photo without redoing the shoot.
• Cleaning up scanned old family photos where dust spots and creases have crept in.

Result

You want to clean up a headshot before printing. Upload the photo, Alt-click a smooth forehead area as source, then brush over a few spots on the cheek. The skin texture blends naturally without any airbrushed look.

FAQ

How is this different from one-click AI skin smoothing?

AI smoothers blur whole regions and tend to leave skin looking plastic. This is a clone stamp: you pick the source texture yourself and paint just the spot you want to fix. Pores and tone stay intact, so the retouch is invisible in print.

What brush size should I use for spots?

Set the brush to roughly twice the size of the blemish — enough to cover the spot in one or two clicks but not so big that you spill onto neighbouring features. For small acne or pores, 12 to 20 px usually works; for larger marks bump up.

Why does my retouch look obvious with a visible seam?

Two common causes: the hardness is too high (try lowering it to 40–60 so the brush feathers into surrounding skin) or the source point is too far away and has different lighting. Re-pick a source closer to the spot and on the same shadow side of the face.

Can I undo a stroke if I make a mistake?

Yes. The Undo button rewinds one paint stroke at a time, so you can experiment with brush size, hardness, and source position without committing. Each Undo step restores the canvas to before that brush stroke.

Does the photo get sent anywhere when I retouch?

No. The canvas, brush, and clone operations all run locally inside your device. Even when you click Download, the image is composed in memory and saved straight to your device — no uploads, no server.
