No. It's a region-targeted brightness, contrast, saturation and unsharp-mask recipe. Everything runs in your browser via the Canvas API.

Why two circles instead of one?

Eyes are always at two distinct points on the face. Two independently positioned circles target both irises in one pass, with no manual brushing.

Will it affect the eyelids or eyebrows?

The circles are feathered, so coverage falls off smoothly past the iris. Use a smaller Eye Radius if you see lids or brows lightening.

Is it safe for darker eye colors?

Yes — brown and hazel eyes gain detail from the Sharpness slider; Color Pop deepens their warm tones rather than washing them out.

Can I use it on photos of pets?

Yes. The circles work the same way on cat, dog or any animal eyes.

Are my photos uploaded?

No. All processing happens locally in the browser tab.

What output format do I get?

Full-resolution PNG. Convert to high-quality JPG afterwards for web upload.

Is there a usage limit?

No signup, no watermark, no cap.

Eye Brightener & Sharpener — Bring Portraits to Life

The eyes are the first thing a viewer looks at in any portrait, but cameras rarely capture them with the brilliance the human eye sees. PikDraw's Eye Brightener gives you two independently positioned soft circles — one per eye — and four sliders that lift brightness, add micro-detail with unsharp masking, punch the iris color and feather the result so the boundary is invisible. The entire pipeline runs in your browser, no AI, no upload.

What is the Eye Brightener & Sharpener — Two-Circle Targeting?

Eye Brightener is a region-targeted enhancement that combines a brightness/contrast/saturation pass with an unsharp-mask sharpening pass, clipped to two feathered elliptical regions positioned over each iris. The brightness lifts the eye, the unsharp-mask exposes the iris pattern, the saturation deepens the color, and the feather hides the mask edge.

Key features

Two independently positioned eye circles — both eyes in one pass
Brightness slider (0–80 %) lifts iris and whites
Sharpness slider (0–100 %) exposes iris micro-detail via unsharp masking
Color Pop (0–100 %) saturates blue, green and brown irises
Adjustable radius and feather for clean blending
Live preview at 800 px, full-resolution PNG export
Pure Canvas pipeline — no AI, no model download, no upload
Free, unlimited, no signup or watermark

How it works

Two feathered ellipses are drawn at the X/Y coordinates you choose, producing a soft per-pixel coverage map. A working copy of the canvas is generated with a CSS filter (brightness × contrast × saturate) applied. If Sharpness is above zero, a second blurred copy is subtracted from the working copy to extract a high-pass detail layer, which is then added back at strength — a classic unsharp mask. The enhanced working copy is clipped to the two-ellipse mask using destination-in compositing, then drawn back over the sharp original. Result: only the eyes change, the rest of the face is bit-for-bit identical.

Why use this tool

Brightening eyes in Lightroom requires a brush mask per eye plus several stacked sliders. AI portrait apps over-process the entire face and upload your photo. PikDraw's Eye Brightener uses two clicks (place each circle), four sliders and stays entirely on your device. Live preview means you stop sliding the moment it looks right.

Common use cases

Headshots and corporate portraits
Wedding and engagement photos
Influencer and creator selfies
Modelling, casting and acting headshots
Dating profile photos with more presence
Pet portraits — same technique works on animal eyes
Yearbook and graduation portraits

How to use this tool

Upload a Portrait — Drop a clear front-facing portrait. The closer the face fills the frame, the better the targeting.
Place the Two Eye Circles — Use Left Eye X/Y and Right Eye X/Y to position the two soft circles directly over each iris.
Size the Radius — Eye Radius 4–7 % covers the iris and a touch of the white. Bigger radius brightens the whole eye socket.
Dial Brightness — 20–40 % lifts the iris and whites without blowing them out.
Add Sharpness — 30–60 % brings back micro-detail on the iris pattern via an unsharp-mask pass.
Punch the Color — Color Pop 20–35 % saturates blue, green and brown irises without affecting the rest of the face.
Feather the Edges — 6–12 px feather hides the circle boundary against the eyelid and surrounding skin.
Export PNG — Download the full-resolution result. Effects scale to the original image size.

Who should use this

Portrait, wedding and event photographers retouching dozens of frames per shoot. Creators publishing daily selfies. Marketers preparing testimonial portraits and team pages. Anyone whose camera flattened the eyes and wants them to read at thumbnail size.

How to get started

Drop your portrait, drag the two circles over each iris, then leave the defaults: Brightness 30 %, Sharpness 45 %, Color Pop 25 %, Radius 5 %, Feather 8 px. Tweak only what feels off.

Best practices

Place circles on the iris, not the whole eye, for the most natural brighten.
Keep Brightness under 50 % unless the original eyes are very dark.
Use Sharpness 30–60 % — past 70 % can introduce halos.
Add 8–12 px feather on high-resolution photos.
Pair with Teeth Whitener and Skin Smoothing for a complete portrait pass.

Pro tips

Two circles let you target both eyes in a single pass — no need to run the tool twice.
Lower Brightness if the eye whites start to glow.
Sharpness above 70 % can introduce halos around lashes — back off if you see them.
Combine with our Red Eye Removal first if flash created red pupils.
For three-quarter angle portraits, set a slightly smaller radius on the far eye.

Expert insights

💡 Two Circles, One Pass

Don't run the tool twice. Position both circles over each iris and dial all four sliders at once.

🔍 Unsharp Mask Explained

Sharpness here is true unsharp masking — high-pass detail added back to the source. That's why iris patterns pop instead of just edges.

⚡ Stack The Pipeline

Run Red Eye Removal first (if needed), then Eye Brightener, then Teeth Whitener, then Skin Smoothing. Magazine portrait in under two minutes.

✓ Halos Are A Warning

If you see bright outlines around lashes, drop Sharpness by 20 %. That's the unsharp mask over-shooting.

⭐ No AI, No Upload

Deterministic Canvas operations only. Nothing leaves your browser tab.

Limitations to be aware of

Targeting is manual — you position the circles. There is no automatic eye detection.
Both circles share the same Radius, Brightness, Sharpness and Color Pop. For asymmetric tweaks, run the tool twice.
Very high sharpness can amplify noise and JPG artefacts.
Live preview is 800 px; the full-resolution result may look slightly different because the unsharp radius scales with pixels.
