AI Relight changes the light in a photo you already have. Upload a portrait, product shot or room, choose golden hour, studio softbox, neon or another lighting preset, set where the light comes from, and the AI redraws highlights, shadows and the color of the light while the subject and composition stay the same. Each AI relight costs 3 credits at 1K.
Upload one photo, choose the new light and its direction, then run AI relight. The credit cost appears on the button before you start.

SAME PHOTO, NEW LIGHT
Each AI relight example starts from one ordinary photo. Switch between lighting styles and drag the slider: the people, objects and framing stay put while the direction, softness and color of the light change.
Illustrative examples created with an AI image model (ChatGPT) from AI-generated sample photos, not outputs of this tool. Results vary by photo.
PORTRAITS
Flat overhead office light makes skin look grey and gives a face no shape. AI relight replaces it with directional light, so cheekbones, hair and fabric pick up highlights and soft shadow while the expression and pose stay the same.
PRODUCT PHOTOS
Direct phone flash leaves a hotspot on glass and a hard shadow on the wall. An AI relight with a studio softbox or a single dramatic key light gives the bottle shape and a premium look without a reshoot.
ROOMS AND INTERIORS
A grey afternoon makes a living room look flat. With AI relight you can switch the lamps on for a blue-hour evening, or add sunlight streaming through the window, with shadows that follow the light from the window.

An AI relight looks believable when the new light could really come from somewhere in the scene. To change the image light source convincingly, look for a window, lamp or open sky in the photo and point the light from that side.
| Direction | What it does | Use it when |
|---|---|---|
| Auto | Lets the AI pick a direction that suits the preset | You are unsure, or the scene has no obvious light source |
| Left / right | Side light that shapes faces and products | A window or lamp is on that side of the frame |
| Front | Even light from the camera position, fewer shadows | You want a clean, catalog-style look |
| Behind (rim) | A glowing outline that separates the subject | Backlit portraits, glass and hair, sunsets behind the subject |
| Above | Overhead light with shadows under the subject | Spotlight drama, food and table-top shots |
Add one JPG, PNG or WebP up to 10 MB. Sharp, well-exposed portraits, products and rooms relight best.
Decide how to light the photo: pick a lighting preset, a direction and a strength. Add a short description if you want something specific, such as warm sun from the left.
Click Relight photo and AI relight returns the new version, usually in under a minute. Drag the slider to compare with the original, then download. Try another light on the same photo to compare looks.
Search for an AI lighting editor, a photo lighting editor or a photo light effect and three kinds of tools show up. They solve different problems.
| AI relight | Brightness / exposure sliders | Light-effect overlays | |
|---|---|---|---|
| Changes where light comes from | Yes | No | No |
| Redraws shadows and highlights | Yes, drawn by the AI | No, brightens existing pixels | No, pastes a flare or glow on top |
| Change time of day or switch lamps on | Yes | No | Only fakes a glow |
| Keeps every original pixel | No, the image is regenerated | Yes | Yes, under the overlay |
| Best for | A different mood or light direction | A photo that is only too dark | A quick decorative flare |
If a photo is only too dark, the Image Brightener is the better fit. If one harsh shadow is the problem, use Remove Shadow from Photo. Image Brightener · Remove Shadow from Photo
A prompt relight works best when the lighting description has four parts: direction, softness, color and time or source. For example, “soft, warm late-afternoon sun from a window on the left”. Use one of these to start.
“Soft, warm late-afternoon sun from a window on the left, gentle shadows on the right side of the face.”
“Large softbox from the left, white fill from the right, soft rim light behind the product, no harsh flash.”
“One narrow hard spotlight from above, the background falling into black, a crisp reflection on the table.”
“Blue dusk outside the window, every lamp in the room switched on with warm pools of light.”
“Bright sunlight streaming through the window on the right, sharp sun patches and long shadows across the floor.”
“Magenta neon sign light from the left, cyan street light from the right, wet reflections, dark background.”
